-# Configuring Azure Pipelines with Certbot
-
-Let's begin. All pipelines are defined in `.azure-pipelines`. Currently there are two:
-* `.azure-pipelines/main.yml` is the main one, executed on PRs for master, and pushes to master,
-* `.azure-pipelines/advanced.yml` add installer testing on top of the main pipeline, and is executed for `test-*` branches, release branches, and nightly run for master.
-
-Several templates are defined in `.azure-pipelines/templates`. These YAML files aggregate common jobs configuration that can be reused in several pipelines.
-
-Unlike Travis, where CodeCov is working without any action required, CodeCov supports Azure Pipelines
-using the coverage-bash utility (not python-coverage for now) only if you provide the Codecov repo token
-using the `CODECOV_TOKEN` environment variable. So `CODECOV_TOKEN` needs to be set as a secured
-environment variable to allow the main pipeline to publish coverage reports to CodeCov.
-
-This INSTALL.md file explains how to configure Azure Pipelines with Certbot in order to execute the CI/CD logic defined in `.azure-pipelines` folder with it.
-During this installation step, warnings describing user access and legal comitments will be displayed like this:
-```
-!!! ACCESS REQUIRED !!!
-```
-
-This document suppose that the Azure DevOps organization is named _certbot_, and the Azure DevOps project is also _certbot_.

-* https://docs.microsoft.com/en-us/azure/devops/pipelines/ecosystems/python?view=azure-devops
-
-## Prerequisites
-
-### Having a GitHub account
-
-Use your GitHub user for a normal GitHub account, or a user that has administrative rights to the GitHub organization if relevant.
-
-### Having an Azure DevOps account
-- Go to https://dev.azure.com/, click "Start free with GitHub"
-- Login to GitHub
-
-```
-!!! ACCESS REQUIRED !!!
-Personal user data (email + profile info, in read-only)
-```
-
-- Microsoft will create a Live account using the email referenced for the GitHub account. This account is also linked to GitHub account (meaning you can log it using GitHub authentication)
-- Proceed with account registration (birth date, country), add details about name and email contact
-
-```
-!!! ACCESS REQUIRED !!!
-Microsoft proposes to send commercial links to this mail
-Azure DevOps terms of service need to be accepted
-```
-
-_Logged to Azure DevOps, account is ready._
-
-### Installing Azure Pipelines to GitHub
-
-- On GitHub, go to Marketplace
-- Select Azure Pipeline, and "Set up a plan"
-- Select Free, then "Install it for free"
-- Click "Complete order and begin installation"
-
-```
-!!! ACCESS !!!
-Azure Pipeline needs RW on code, RO on metadata, RW on checks, commit statuses, deployments, issues, pull requests.
-RW access here is required to allow update of the pipelines YAML files from Azure DevOps interface, and to
-update the status of builds and PRs on GitHub side when Azure Pipelines are triggered.
-Note however that no admin access is defined here: this means that Azure Pipelines cannot do anything with
-protected branches, like master, and cannot modify the security context around this on GitHub.
-Access can be defined for all or only selected repositories, which is nice.
-```
-
-- Redirected to Azure DevOps, select the account created in _Having an Azure DevOps account_ section.
-- Select the organization, and click "Create a new project" (let's name it the same than the targetted github repo)
-- The Visibility is public, to profit from 10 parallel jobs
-
-```
-!!! ACCESS !!!
-Azure Pipelines needs access to the GitHub account (in term of beeing able to check it is valid), and the Resources shared between the GitHub account and Azure Pipelines.
-```
-
-_Done. We can move to pipelines configuration._
-
-## Import an existing pipelines from `.azure-pipelines` folder
-
-- On Azure DevOps, go to your organization (eg. _certbot_) then your project (eg. _certbot_)
-- Click "Pipelines" tab
-- Click "New pipeline"
-- Where is your code?: select "__Use the classic editor__"
-
-__Warning: Do not choose the GitHub option in Where is your code? section. Indeed, this option will trigger an OAuth
-grant permissions from Azure Pipelines to GitHub in order to setup a GitHub OAuth Application. The permissions asked
-then are way too large (admin level on almost everything), while the classic approach does not add any more
-permissions, and works perfectly well.__
-
-- Select GitHub in "Select your repository section", choose certbot/certbot in Repository, master in default branch.
-- Click on YAML option for "Select a template"
-- Choose a name for the pipeline (eg. test-pipeline), and browse to the actual pipeline YAML definition in the
-  "YAML file path" input (eg. `.azure-pipelines/test-pipeline.yml`)
-- Click "Save & queue", choose the master branch to build the first pipeline, and click "Save and run" button.
-
-_Done. Pipeline is operational. Repeat to add more pipelines from existing YAML files in `.azure-pipelines`._
-
-## Add a secret variable to a pipeline (like `CODECOV_TOKEN`)
-
-__NB: Following steps suppose that you already setup the YAML pipeline file to
-consume the secret variable that these steps will create as an environment variable.
-For a variable named `CODECOV_TOKEN` consuming the variable `codecov_token`,
-in the YAML file this setup would take the form of the following:
-```
-steps:
-    - script: ./do_something_that_consumes_CODECOV_TOKEN  # Eg. `codecov -F windows`
-      env:
-        CODECOV_TOKEN: $(codecov_token)
-```
-
-To set up a variable that is shared between pipelines, follow the instructions
-at
-https://docs.microsoft.com/en-us/azure/devops/pipelines/library/variable-groups.
-When adding variables to a group, don't forget to tick "Keep this value secret"
-if it shouldn't be shared publcily.

+# Certbot change log
+
+Certbot adheres to [Semantic Versioning](http://semver.org/).
+
+## 0.22.2 - 2018-03-19
+
+### Fixed
+
+* A type error introduced in 0.22.1 that would occur during challenge cleanup
+  when a Certbot plugin raises an exception while trying to complete the
+  challenge was fixed.
+
+Despite us having broken lockstep, we are continuing to release new versions of
+all Certbot components during releases for the time being, however, the only
+packages with changes other than their version number were:
+
+* certbot
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/53?closed=1
+
+## 0.22.1 - 2018-03-19
+
+### Changed
+
+* The ACME server used with Certbot's --dry-run and --staging flags is now
+  Let's Encrypt's ACMEv2 staging server which allows people to also test ACMEv2
+  features with these flags.
+
+### Fixed
+
+* The HTTP Content-Type header is now set to the correct value during
+  certificate revocation with new versions of the ACME protocol.
+* When using Certbot with Let's Encrypt's ACMEv2 server, it would add a blank
+  line to the top of chain.pem and between the certificates in fullchain.pem
+  for each lineage. These blank lines have been removed.
+* Resolved a bug that caused Certbot's --allow-subset-of-names flag not to
+  work.
+* Fixed a regression in acme.client.Client that caused the class to not work
+  when it was initialized without a ClientNetwork which is done by some of the
+  other projects using our ACME library.

+
+## 0.22.0 - 2018-03-07
+
+### Added
+
+* Support for obtaining wildcard certificates and a newer version of the ACME
+  protocol such as the one implemented by Let's Encrypt's upcoming ACMEv2
+  endpoint was added to Certbot and its ACME library. Certbot still works with
+  older ACME versions and will automatically change the version of the protocol
+  used based on the version the ACME CA implements.
+* The Apache and Nginx plugins are now able to automatically install a wildcard
+  certificate to multiple virtual hosts that you select from your server
+  configuration.
+* The `certbot install` command now accepts the `--cert-name` flag for
+  selecting a certificate.
+* `acme.client.BackwardsCompatibleClientV2` was added to Certbot's ACME library
+  which automatically handles most of the differences between new and old ACME
+  versions. `acme.client.ClientV2` is also available for people who only want
+  to support one version of the protocol or want to handle the differences
+  between versions themselves.
+* certbot-auto now supports the flag --install-only which has the script
+  install Certbot and its dependencies and exit without invoking Certbot.
+* Support for issuing a single certificate for a wildcard and base domain was
+  added to our Google Cloud DNS plugin. To do this, we now require your API
+  credentials have additional permissions, however, your credentials will
+  already have these permissions unless you defined a custom role with fewer
+  permissions than the standard DNS administrator role provided by Google.
+  These permissions are also only needed for the case described above so it
+  will continue to work for existing users. For more information about the
+  permissions changes, see the documentation in the plugin.
+
+### Changed
+
+* We have broken lockstep between our ACME library, Certbot, and its plugins.
+  This means that the different components do not need to be the same version
+  to work together like they did previously. This makes packaging easier
+  because not every piece of Certbot needs to be repackaged to ship a change to
+  a subset of its components.
+* Support for Python 2.6 and Python 3.3 has been removed from ACME, Certbot,
+  Certbot's plugins, and certbot-auto. If you are using certbot-auto on a RHEL
+  6 based system, it will walk you through the process of installing Certbot
+  with Python 3 and refuse to upgrade to a newer version of Certbot until you
+  have done so.
+* Certbot's components now work with older versions of setuptools to simplify
+  packaging for EPEL 7.
+
+### Fixed
+
+* Issues caused by Certbot's Nginx plugin adding multiple ipv6only directives
+  has been resolved.
+* A problem where Certbot's Apache plugin would add redundant include
+  directives for the TLS configuration managed by Certbot has been fixed.
+* Certbot's webroot plugin now properly deletes any directories it creates.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/48?closed=1
+
+## 0.21.1 - 2018-01-25
+
+### Fixed
+
+* When creating an HTTP to HTTPS redirect in Nginx, we now ensure the Host
+  header of the request is set to an expected value before redirecting users to
+  the domain found in the header. The previous way Certbot configured Nginx
+  redirects was a potential security issue which you can read more about at
+  https://community.letsencrypt.org/t/security-issue-with-redirects-added-by-certbots-nginx-plugin/51493.
+* Fixed a problem where Certbot's Apache plugin could fail HTTP-01 challenges
+  if basic authentication is configured for the domain you request a
+  certificate for.
+* certbot-auto --no-bootstrap now properly tries to use Python 3.4 on RHEL 6
+  based systems rather than Python 2.6.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/49?closed=1
+
+## 0.21.0 - 2018-01-17
+
+### Added
+
+* Support for the HTTP-01 challenge type was added to our Apache and Nginx
+  plugins. For those not aware, Let's Encrypt disabled the TLS-SNI-01 challenge
+  type which was what was previously being used by our Apache and Nginx plugins
+  last week due to a security issue. For more information about Let's Encrypt's
+  change, click
+  [here](https://community.letsencrypt.org/t/2018-01-11-update-regarding-acme-tls-sni-and-shared-hosting-infrastructure/50188).
+  Our Apache and Nginx plugins will automatically switch to use HTTP-01 so no
+  changes need to be made to your Certbot configuration, however, you should
+  make sure your server is accessible on port 80 and isn't behind an external
+  proxy doing things like redirecting all traffic from HTTP to HTTPS. HTTP to
+  HTTPS redirects inside Apache and Nginx are fine.
+* IPv6 support was added to the Nginx plugin.
+* Support for automatically creating server blocks based on the default server
+  block was added to the Nginx plugin.
+* The flags --delete-after-revoke and --no-delete-after-revoke were added
+  allowing users to control whether the revoke subcommand also deletes the
+  certificates it is revoking.
+
+### Changed
+
+* We deprecated support for Python 2.6 and Python 3.3 in Certbot and its ACME
+  library. Support for these versions of Python will be removed in the next
+  major release of Certbot. If you are using certbot-auto on a RHEL 6 based
+  system, it will guide you through the process of installing Python 3.
+* We split our implementation of JOSE (Javascript Object Signing and
+  Encryption) out of our ACME library and into a separate package named josepy.
+  This package is available on [PyPI](https://pypi.python.org/pypi/josepy) and
+  on [GitHub](https://github.com/certbot/josepy).
+* We updated the ciphersuites used in Apache to the new [values recommended by
+  Mozilla](https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28default.29).
+  The major change here is adding ChaCha20 to the list of supported
+  ciphersuites.
+
+### Fixed
+
+* An issue with our Apache plugin on Gentoo due to differences in their
+  apache2ctl command have been resolved.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/47?closed=1
+
+## 0.20.0 - 2017-12-06
+
+### Added
+
+* Certbot's ACME library now recognizes URL fields in challenge objects in
+  preparation for Let's Encrypt's new ACME endpoint. The value is still
+  accessible in our ACME library through the name "uri".
+
+### Changed
+
+* The Apache plugin now parses some distro specific Apache configuration files
+  on non-Debian systems allowing it to get a clearer picture on the running
+  configuration. Internally, these changes were structured so that external
+  contributors can easily write patches to make the plugin work in new Apache
+  configurations.
+* Certbot better reports network failures by removing information about
+  connection retries from the error output.
+* An unnecessary question when using Certbot's webroot plugin interactively has
+  been removed.
+
+### Fixed
+
+* Certbot's NGINX plugin no longer sometimes incorrectly reports that it was
+  unable to deploy a HTTP->HTTPS redirect when requesting Certbot to enable a
+  redirect for multiple domains.
+* Problems where the Apache plugin was failing to find directives and
+  duplicating existing directives on openSUSE have been resolved.
+* An issue running the test shipped with Certbot and some our DNS plugins with
+  older versions of mock have been resolved.
+* On some systems, users reported strangely interleaved output depending on
+  when stdout and stderr were flushed. This problem was resolved by having
+  Certbot regularly flush these streams.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/44?closed=1
+
+## 0.19.0 - 2017-10-04
+
+### Added
+
+* Certbot now has renewal hook directories where executable files can be placed
+  for Certbot to run with the renew subcommand. Pre-hooks, deploy-hooks, and
+  post-hooks can be specified in the renewal-hooks/pre, renewal-hooks/deploy,
+  and renewal-hooks/post directories respectively in Certbot's configuration
+  directory (which is /etc/letsencrypt by default). Certbot will automatically
+  create these directories when it is run if they do not already exist.
+* After revoking a certificate with the revoke subcommand, Certbot will offer
+  to delete the lineage associated with the certificate. When Certbot is run
+  with --non-interactive, it will automatically try to delete the associated
+  lineage.
+* When using Certbot's Google Cloud DNS plugin on Google Compute Engine, you no
+  longer have to provide a credential file to Certbot if you have configured
+  sufficient permissions for the instance which Certbot can automatically
+  obtain using Google's metadata service.
+
+### Changed
+
+* When deleting certificates interactively using the delete subcommand, Certbot
+  will now allow you to select multiple lineages to be deleted at once.
+* Certbot's Apache plugin no longer always parses Apache's sites-available on
+  Debian based systems and instead only parses virtual hosts included in your
+  Apache configuration. You can provide an additional directory for Certbot to
+  parse using the command line flag --apache-vhost-root.
+
+### Fixed
+
+* The plugins subcommand can now be run without root access.
+* certbot-auto now includes a timeout when updating itself so it no longer
+  hangs indefinitely when it is unable to connect to the external server.
+* An issue where Certbot's Apache plugin would sometimes fail to deploy a
+  certificate on Debian based systems if mod_ssl wasn't already enabled has
+  been resolved.
+* A bug in our Docker image where the certificates subcommand could not report
+  if certificates maintained by Certbot had been revoked has been fixed.
+* Certbot's RFC 2136 DNS plugin (for use with software like BIND) now properly
+  performs DNS challenges when the domain being verified contains a CNAME
+  record.

+
+## 0.18.2 - 2017-09-20
+
+### Fixed
+
+* An issue where Certbot's ACME module would raise an AttributeError trying to
+  create self-signed certificates when used with pyOpenSSL 17.3.0 has been
+  resolved. For Certbot users with this version of pyOpenSSL, this caused
+  Certbot to crash when performing a TLS SNI challenge or when the Nginx plugin
+  tried to create an SSL server block.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/46?closed=1
+
+## 0.18.1 - 2017-09-08
+
+### Fixed
+
+* If certbot-auto was running as an unprivileged user and it upgraded from
+  0.17.0 to 0.18.0, it would crash with a permissions error and would need to
+  be run again to successfully complete the upgrade. This has been fixed and
+  certbot-auto should upgrade cleanly to 0.18.1.
+* Certbot usually uses "certbot-auto" or "letsencrypt-auto" in error messages
+  and the User-Agent string instead of "certbot" when you are using one of
+  these wrapper scripts. Proper detection of this was broken with Certbot's new
+  installation path in /opt in 0.18.0 but this problem has been resolved.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/45?closed=1
+
+## 0.18.0 - 2017-09-06
+
+### Added
+
+* The Nginx plugin now configures Nginx to use 2048-bit Diffie-Hellman
+  parameters. Java 6 clients do not support Diffie-Hellman parameters larger
+  than 1024 bits, so if you need to support these clients you will need to
+  manually modify your Nginx configuration after using the Nginx installer.
+
+### Changed
+
+* certbot-auto now installs Certbot in directories under `/opt/eff.org`. If you
+  had an existing installation from certbot-auto, a symlink is created to the
+  new directory. You can configure certbot-auto to use a different path by
+  setting the environment variable VENV_PATH.
+* The Nginx plugin can now be selected in Certbot's interactive output.
+* Output verbosity of renewal failures when running with `--quiet` has been
+  reduced.
+* The default revocation reason shown in Certbot help output now is a human
+  readable string instead of a numerical code.
+* Plugin selection is now included in normal terminal output.
+
+### Fixed
+
+* A newer version of ConfigArgParse is now installed when using certbot-auto
+  causing values set to false in a Certbot INI configuration file to be handled
+  intuitively. Setting a boolean command line flag to false is equivalent to
+  not including it in the configuration file at all.
+* New naming conventions preventing certbot-auto from installing OS
+  dependencies on Fedora 26 have been resolved.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/42?closed=1
+
+## 0.17.0 - 2017-08-02
+
+### Added
+
+* Support in our nginx plugin for modifying SSL server blocks that do
+  not contain certificate or key directives.
+* A `--max-log-backups` flag to allow users to configure or even completely
+  disable Certbot's built in log rotation.
+* A `--user-agent-comment` flag to allow people who build tools around Certbot
+  to differentiate their user agent string by adding a comment to its default
+  value.
+
+### Changed
+
+* Due to some awesome work by
+  [cryptography project](https://github.com/pyca/cryptography), compilation can
+  now be avoided on most systems when using certbot-auto. This eliminates many
+  problems people have had in the past such as running out of memory, having
+  invalid headers/libraries, and changes to the OS packages on their system
+  after compilation breaking Certbot.
+* The `--renew-hook` flag has been hidden in favor of `--deploy-hook`. This new
+  flag works exactly the same way except it is always run when a certificate is
+  issued rather than just when it is renewed.
+* We have started printing deprecation warnings in certbot-auto for
+  experimentally supported systems with OS packages available.
+* A certificate lineage's name is included in error messages during renewal.
+
+### Fixed
+
+* Encoding errors that could occur when parsing error messages from the ACME
+  server containing Unicode have been resolved.
+* certbot-auto no longer prints misleading messages about there being a newer
+  pip version available when installation fails.
+* Certbot's ACME library now properly extracts domains from critical SAN
+  extensions.
+
+More details about these changes can be found on our GitHub repo:

+
+## 0.16.0 - 2017-07-05
+
+### Added
+
+* A plugin for performing DNS challenges using dynamic DNS updates as defined
+  in RFC 2316. This plugin is packaged separately from Certbot and is available
+  at https://pypi.python.org/pypi/certbot-dns-rfc2136. It supports Python 2.6,
+  2.7, and 3.3+. At this time, there isn't a good way to install this plugin
+  when using certbot-auto, but this should change in the near future.
+* Plugins for performing DNS challenges for the providers
+  [DNS Made Easy](https://pypi.python.org/pypi/certbot-dns-dnsmadeeasy) and
+  [LuaDNS](https://pypi.python.org/pypi/certbot-dns-luadns). These plugins are
+  packaged separately from Certbot and support Python 2.7 and 3.3+. Currently,
+  there isn't a good way to install these plugins when using certbot-auto,
+  but that should change soon.
+* Support for performing TLS-SNI-01 challenges when using the manual plugin.
+* Automatic detection of Arch Linux in the Apache plugin providing better
+  default settings for the plugin.
+
+### Changed
+
+* The text of the interactive question about whether a redirect from HTTP to
+  HTTPS should be added by Certbot has been rewritten to better explain the
+  choices to the user.
+* Simplified HTTP challenge instructions in the manual plugin.
+
+### Fixed
+
+* Problems performing a dry run when using the Nginx plugin have been fixed.
+* Resolved an issue where certbot-dns-digitalocean's test suite would sometimes
+  fail when ran using Python 3.
+* On some systems, previous versions of certbot-auto would error out with a
+  message about a missing hash for setuptools. This has been fixed.
+* A bug where Certbot would sometimes not print a space at the end of an
+  interactive prompt has been resolved.
+* Nonfatal tracebacks are no longer shown in rare cases where Certbot
+  encounters an exception trying to close its TCP connection with the ACME
+  server.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.16.0+is%3Aclosed
+
+## 0.15.0 - 2017-06-08
+
+### Added
+
+* Plugins for performing DNS challenges for popular providers. Like the Apache
+  and Nginx plugins, these plugins are packaged separately and not included in
+  Certbot by default. So far, we have plugins for
+  [Amazon Route 53](https://pypi.python.org/pypi/certbot-dns-route53),
+  [Cloudflare](https://pypi.python.org/pypi/certbot-dns-cloudflare),
+  [DigitalOcean](https://pypi.python.org/pypi/certbot-dns-digitalocean), and
+  [Google Cloud](https://pypi.python.org/pypi/certbot-dns-google) which all
+  work on Python 2.6, 2.7, and 3.3+. Additionally, we have plugins for
+  [CloudXNS](https://pypi.python.org/pypi/certbot-dns-cloudxns),
+  [DNSimple](https://pypi.python.org/pypi/certbot-dns-dnsimple),
+  [NS1](https://pypi.python.org/pypi/certbot-dns-nsone) which work on Python
+  2.7 and 3.3+ (and not 2.6). Currently, there isn't a good way to install
+  these plugins when using `certbot-auto`, but that should change soon.
+* IPv6 support in the standalone plugin. When performing a challenge, the
+  standalone plugin automatically handles listening for IPv4/IPv6 traffic based
+  on the configuration of your system.
+* A mechanism for keeping your Apache and Nginx SSL/TLS configuration up to
+  date. When the Apache or Nginx plugins are used, they place SSL/TLS
+  configuration options in the root of Certbot's config directory
+  (`/etc/letsencrypt` by default). Now when a new version of these plugins run
+  on your system, they will automatically update the file to the newest
+  version if it is unmodified. If you manually modified the file, Certbot will
+  display a warning giving you a path to the updated file which you can use as
+  a reference to manually update your modified copy.
+* `--http-01-address` and `--tls-sni-01-address` flags for controlling the
+  address Certbot listens on when using the standalone plugin.
+* The command `certbot certificates` that lists certificates managed by Certbot
+  now performs additional validity checks to notify you if your files have
+  become corrupted.
+
+### Changed
+
+* Messages custom hooks print to `stdout` are now displayed by Certbot when not
+  running in `--quiet` mode.
+* `jwk` and `alg` fields in JWS objects have been moved into the protected
+  header causing Certbot to more closely follow the latest version of the ACME
+  spec.
+
+### Fixed
+
+* Permissions on renewal configuration files are now properly preserved when
+  they are updated.
+* A bug causing Certbot to display strange defaults in its help output when
+  using Python <= 2.7.4 has been fixed.
+* Certbot now properly handles mixed case domain names found in custom CSRs.
+* A number of poorly worded prompts and error messages.
+
+### Removed
+
+* Support for OpenSSL 1.0.0 in `certbot-auto` has been removed as we now pin a
+  newer version of `cryptography` which dropped support for this version.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.15.0+is%3Aclosed
+
+## 0.14.2 - 2017-05-25
+
+### Fixed
+
+* Certbot 0.14.0 included a bug where Certbot would create a temporary log file
+(usually in /tmp) if the program exited during argument parsing. If a user
+provided -h/--help/help, --version, or an invalid command line argument,
+Certbot would create this temporary log file. This was especially bothersome to
+certbot-auto users as certbot-auto runs `certbot --version` internally to see
+if the script needs to upgrade causing it to create at least one of these files
+on every run. This problem has been resolved.
+
+More details about this change can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.14.2+is%3Aclosed
+
+## 0.14.1 - 2017-05-16
+
+### Fixed
+
+* Certbot now works with configargparse 0.12.0.
+* Issues with the Apache plugin and Augeas 1.7+ have been resolved.
+* A problem where the Nginx plugin would fail to install certificates on
+systems that had the plugin's SSL/TLS options file from 7+ months ago has been
+fixed.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.14.1+is%3Aclosed
+
+## 0.14.0 - 2017-05-04
+
+### Added
+
+* Python 3.3+ support for all Certbot packages. `certbot-auto` still currently
+only supports Python 2, but the `acme`, `certbot`, `certbot-apache`, and
+`certbot-nginx` packages on PyPI now fully support Python 2.6, 2.7, and 3.3+.
+* Certbot's Apache plugin now handles multiple virtual hosts per file.
+* Lockfiles to prevent multiple versions of Certbot running simultaneously.
+
+### Changed
+
+* When converting an HTTP virtual host to HTTPS in Apache, Certbot only copies
+the virtual host rather than the entire contents of the file it's contained
+in.
+* The Nginx plugin now includes SSL/TLS directives in a separate file located
+in Certbot's configuration directory rather than copying the contents of the
+file into every modified `server` block.
+
+### Fixed
+
+* Ensure logging is configured before parts of Certbot attempt to log any
+messages.
+* Support for the `--quiet` flag in `certbot-auto`.
+* Reverted a change made in a previous release to make the `acme` and `certbot`
+packages always depend on `argparse`. This dependency is conditional again on
+the user's Python version.
+* Small bugs in the Nginx plugin such as properly handling empty `server`
+blocks and setting `server_names_hash_bucket_size` during challenges.
+
+As always, a more complete list of changes can be found on GitHub:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.14.0+is%3Aclosed
+
+## 0.13.0 - 2017-04-06
+
+### Added
+
+* `--debug-challenges` now pauses Certbot after setting up challenges for debugging.
+* The Nginx parser can now handle all valid directives in configuration files.
+* Nginx ciphersuites have changed to Mozilla Intermediate.
+* `certbot-auto --no-bootstrap` provides the option to not install OS dependencies.
+
+### Fixed
+
+* `--register-unsafely-without-email` now respects `--quiet`.
+* Hyphenated renewal parameters are now saved in renewal config files.
+* `--dry-run` no longer persists keys and csrs.
+* Certbot no longer hangs when trying to start Nginx in Arch Linux.
+* Apache rewrite rules no longer double-encode characters.
+
+A full list of changes is available on GitHub:
+https://github.com/certbot/certbot/issues?q=is%3Aissue%20milestone%3A0.13.0%20is%3Aclosed%20
+
+## 0.12.0 - 2017-03-02
+
+### Added
+
+* Certbot now allows non-camelcase Apache VirtualHost names.
+* Certbot now allows more log messages to be silenced.
+
+### Fixed
+
+* Fixed a regression around using `--cert-name` when getting new certificates
+
+More information about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue%20milestone%3A0.12.0
+
+## 0.11.1 - 2017-02-01
+
+### Fixed
+
+* Resolved a problem where Certbot would crash while parsing command line
+arguments in some cases.
+* Fixed a typo.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/pulls?q=is%3Apr%20milestone%3A0.11.1%20is%3Aclosed
+
+## 0.11.0 - 2017-02-01
+
+### Added
+
+* When using the standalone plugin while running Certbot interactively 
+and a required port is bound by another process, Certbot will give you
+the option to retry to grab the port rather than immediately exiting.
+* You are now able to deactivate your account with the Let's Encrypt
+server using the `unregister` subcommand.
+* When revoking a certificate using the `revoke` subcommand, you now
+have the option to provide the reason the certificate is being revoked
+to Let's Encrypt with `--reason`.
+
+### Changed
+
+* Providing `--quiet` to `certbot-auto` now silences package manager output.
+
+### Removed
+
+* Removed the optional `dnspython` dependency in our `acme` package.
+Now the library does not support client side verification of the DNS
+challenge.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.11.0+is%3Aclosed
+
+## 0.10.2 - 2017-01-25
+
+### Added
+
+* If Certbot receives a request with a `badNonce` error, it now
+automatically retries the request. Since nonces from Let's Encrypt expire,
+this helps people performing the DNS challenge with the `manual` plugin
+who may have to wait an extended period of time for their DNS changes to
+propagate.
+
+### Fixed
+
+* Certbot now saves the `--preferred-challenges` values for renewal. Previously
+these values were discarded causing a different challenge type to be used when
+renewing certs in some cases.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.10.2+is%3Aclosed
+
+## 0.10.1 - 2017-01-13
+
+### Fixed
+
+* Resolve problems where when asking Certbot to update a certificate at
+an existing path to include different domain names, the old names would
+continue to be used.
+* Fix issues successfully running our unit test suite on some systems.
+
+More details about these changes can be found on our GitHub repo:

+
+## 0.10.0 - 2017-01-11
+
+## Added
+
+* Added the ability to customize and automatically complete DNS and HTTP
+domain validation challenges with the manual plugin. The flags
+`--manual-auth-hook` and `--manual-cleanup-hook` can now be provided
+when using the manual plugin to execute commands provided by the user to
+perform and clean up challenges provided by the CA. This is best used in
+complicated setups where the DNS challenge must be used or Certbot's
+existing plugins cannot be used to perform HTTP challenges. For more
+information on how this works, see `certbot --help manual`.
+* Added a `--cert-name` flag for specifying the name to use for the
+certificate in Certbot's configuration directory. Using this flag in
+combination with `-d/--domains`, a user can easily request a new
+certificate with different domains and save it with the name provided by
+`--cert-name`. Additionally, `--cert-name` can be used to select a
+certificate with the `certonly` and `run` subcommands so a full list of
+domains in the certificate does not have to be provided.
+* Added subcommand `certificates` for listing the certificates managed by
+Certbot and their properties.
+* Added the `delete` subcommand for removing certificates managed by Certbot
+from the configuration directory.
+* Certbot now supports requesting internationalized domain names (IDNs).
+* Hooks provided to Certbot are now saved to be reused during renewal.
+If you run Certbot with `--pre-hook`, `--renew-hook`, or `--post-hook`
+flags when obtaining a certificate, the provided commands will
+automatically be saved and executed again when renewing the certificate.
+A pre-hook and/or post-hook can also be given to the `certbot renew`
+command either on the command line or in a [configuration
+file](https://certbot.eff.org/docs/using.html#configuration-file) to run
+an additional command before/after any certificate is renewed. Hooks
+will only be run if a certificate is renewed.
+* Support Busybox in certbot-auto.
+
+### Changed
+
+* Recategorized `-h/--help` output to improve documentation and
+discoverability.
+
+### Removed
+
+* Removed the ncurses interface. This change solves problems people
+were having on many systems, reduces the number of Certbot
+dependencies, and simplifies our code. Certbot's only interface now is
+the text interface which was available by providing `-t/--text` to
+earlier versions of Certbot.
+
+### Fixed
+
+* Many small bug fixes.
+
+More details about these changes can be found on our GitHub repo:

+
+## 0.9.3 - 2016-10-13
+
+### Added
+
+* The Apache plugin uses information about your OS to help determine the
+layout of your Apache configuration directory. We added a patch to
+ensure this code behaves the same way when testing on different systems
+as the tests were failing in some cases.
+
+### Changed
+
+* Certbot adopted more conservative behavior about reporting a needed port as
+unavailable when using the standalone plugin.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/27?closed=1
+
+## 0.9.2 - 2016-10-12
+
+### Added
+
+* Certbot stopped requiring that all possibly required ports are available when
+using the standalone plugin. It now only verifies that the ports are available
+when they are necessary.
+
+### Fixed
+
+* Certbot now verifies that our optional dependencies version matches what is
+required by Certbot.
+* Certnot now properly copies the `ssl on;` directives as necessary when
+performing domain validation in the Nginx plugin.
+* Fixed problem where symlinks were becoming files when they were
+packaged, causing errors during testing and OS packaging.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/26?closed=1
+
+## 0.9.1 - 2016-10-06
+
+### Fixed
+
+* Fixed a bug that was introduced in version 0.9.0 where the command
+line flag -q/--quiet wasn't respected in some cases.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/milestone/25?closed=1
+
+## 0.9.0 - 2016-10-05
+
+### Added
+
+* Added an alpha version of the Nginx plugin. This plugin fully automates the
+process of obtaining and installing certificates with Nginx.
+Additionally, it is able to automatically configure security
+enhancements such as an HTTP to HTTPS redirect and OCSP stapling. To use
+this plugin, you must have the `certbot-nginx` package installed (which
+is installed automatically when using `certbot-auto`) and provide
+`--nginx` on the command line. This plugin is still in its early stages
+so we recommend you use it with some caution and make sure you have a
+backup of your Nginx configuration.
+* Added support for the `DNS` challenge in the `acme` library and `DNS` in
+Certbot's `manual` plugin. This allows you to create DNS records to
+prove to Let's Encrypt you control the requested domain name. To use
+this feature, include `--manual --preferred-challenges dns` on the
+command line.
+* Certbot now helps with enabling Extra Packages for Enterprise Linux (EPEL) on
+CentOS 6 when using `certbot-auto`. To use `certbot-auto` on CentOS 6,
+the EPEL repository has to be enabled. `certbot-auto` will now prompt
+users asking them if they would like the script to enable this for them
+automatically. This is done without prompting users when using
+`letsencrypt-auto` or if `-n/--non-interactive/--noninteractive` is
+included on the command line.

+
+## 0.8.1 - 2016-06-14
+
+### Added
+
+* Certbot now preserves a certificate's common name when using `renew`.
+* Certbot now saves webroot values for renewal when they are entered interactively.
+* Certbot now gracefully reports that the Apache plugin isn't usable when Augeas is not installed.
+* Added experimental support for Mageia has been added to `certbot-auto`.
+
+### Fixed
+
+* Fixed problems with an invalid user-agent string on OS X.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.8.1+
+
+## 0.8.0 - 2016-06-02
+
+### Added
+
+* Added the `register` subcommand which can be used to register an account
+with the Let's Encrypt CA.
+* You can now run `certbot register --update-registration` to
+change the e-mail address associated with your registration.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue+milestone%3A0.8.0+
+
+## 0.7.0 - 2016-05-27
+
+### Added
+
+* Added `--must-staple` to request certificates from Let's Encrypt
+with the OCSP must staple extension.
+* Certbot now automatically configures OSCP stapling for Apache.
+* Certbot now allows requesting certificates for domains found in the common name
+of a custom CSR.
+
+### Fixed
+
+* Fixed a number of miscellaneous bugs
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=milestone%3A0.7.0+is%3Aissue
+
+## 0.6.0 - 2016-05-12
+
+### Added
+
+* Versioned the datetime dependency in setup.py.
+
+### Changed
+
+* Renamed the client from `letsencrypt` to `certbot`.
+
+### Fixed
+
+* Fixed a small json deserialization error.
+* Certbot now preserves domain order in generated CSRs.
+* Fixed some minor bugs.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/certbot/certbot/issues?q=is%3Aissue%20milestone%3A0.6.0%20is%3Aclosed%20
+
+## 0.5.0 - 2016-04-05
+
+### Added
+
+* Added the ability to use the webroot plugin interactively.
+* Added the flags --pre-hook, --post-hook, and --renew-hook which can be used with
+the renew subcommand to register shell commands to run in response to
+renewal events. Pre-hook commands will be run before any certs are
+renewed, post-hook commands will be run after any certs are renewed,
+and renew-hook commands will be run after each cert is renewed. If no
+certs are due for renewal, no command is run.
+* Added a -q/--quiet flag which silences all output except errors.
+* Added an --allow-subset-of-domains flag which can be used with the renew
+command to prevent renewal failures for a subset of the requested
+domains from causing the client to exit.
+
+### Changed
+
+* Certbot now uses renewal configuration files. In /etc/letsencrypt/renewal
+by default, these files can be used to control what parameters are
+used when renewing a specific certificate.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/letsencrypt/letsencrypt/issues?q=milestone%3A0.5.0+is%3Aissue
+
+## 0.4.2 - 2016-03-03
+
+### Fixed
+
+* Resolved problems encountered when compiling letsencrypt
+against the new OpenSSL release.
+* Fixed problems encountered when using `letsencrypt renew` with configuration files
+from the private beta.

+
+## 0.4.1 - 2016-02-29
+
+### Fixed
+
+* Fixed Apache parsing errors encountered with some configurations.
+* Fixed Werkzeug dependency problems encountered on some Red Hat systems.
+* Fixed bootstrapping failures when using letsencrypt-auto with --no-self-upgrade.
+* Fixed problems with parsing renewal config files from private beta.
+

+https://github.com/letsencrypt/letsencrypt/issues?q=is:issue+milestone:0.4.1
+
+## 0.4.0 - 2016-02-10
+
+### Added
+
+* Added the verb/subcommand `renew` which can be used to renew your existing
+certificates as they approach expiration. Running `letsencrypt renew`
+will examine all existing certificate lineages and determine if any are
+less than 30 days from expiration. If so, the client will use the
+settings provided when you previously obtained the certificate to renew
+it. The subcommand finishes by printing a summary of which renewals were
+successful, failed, or not yet due.
+* Added a `--dry-run` flag to help with testing configuration
+without affecting production rate limits. Currently supported by the
+`renew` and `certonly` subcommands, providing `--dry-run` on the command
+line will obtain certificates from the staging server without saving the
+resulting certificates to disk.
+* Added major improvements to letsencrypt-auto. This script
+has been rewritten to include full support for Python 2.6, the ability
+for letsencrypt-auto to update itself, and improvements to the
+stability, security, and performance of the script.
+* Added support for Apache 2.2 to the Apache plugin.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/letsencrypt/letsencrypt/issues?q=is%3Aissue+milestone%3A0.4.0
+
+## 0.3.0 - 2016-01-27
+
+### Added
+
+* Added a non-interactive mode which can be enabled by including `-n` or
+`--non-interactive` on the command line. This can be used to guarantee
+the client will not prompt when run automatically using cron/systemd.
+* Added preparation for the new letsencrypt-auto script. Over the past
+couple months, we've been working on increasing the reliability and
+security of letsencrypt-auto. A number of changes landed in this
+release to prepare for the new version of this script.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/letsencrypt/letsencrypt/issues?q=is%3Aissue+milestone%3A0.3.0
+
+## 0.2.0 - 2016-01-14
+
+### Added
+
+* Added Apache plugin support for non-Debian based systems. Support has been
+added for modern Red Hat based systems such as Fedora 23, Red Hat 7,
+and CentOS 7 running Apache 2.4. In theory, this plugin should be
+able to be configured to run on any Unix-like OS running Apache 2.4.
+* Relaxed PyOpenSSL version requirements. This adds support for systems
+with PyOpenSSL versions 0.13 or 0.14.
+* Improved error messages from the client.
+
+### Fixed
+
+* Resolved issues with the Apache plugin enabling an HTTP to HTTPS
+redirect on some systems.
+
+More details about these changes can be found on our GitHub repo:
+https://github.com/letsencrypt/letsencrypt/issues?q=is%3Aissue+milestone%3A0.2.0
+
+## 0.1.1 - 2015-12-15
+
+### Added
+
+* Added a check that avoids attempting to issue for unqualified domain names like
+"localhost".
+
+### Fixed
+
+* Fixed a confusing UI path that caused some users to repeatedly renew
+their certs while experimenting with the client, in some cases hitting
+issuance rate limits.
+* Fixed numerous Apache configuration parser problems
+* Fixed --webroot permission handling for non-root users

+
+Certbot is part of EFF’s effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identity of web servers (e.g., is that really google.com?). Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Let’s Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.
+
+Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate is. Certbot and Let’s Encrypt can automate away the pain and let you turn on and manage HTTPS with simple commands. Using Certbot and Let's Encrypt is free, so there’s no need to arrange payment.
+
+How you use Certbot depends on the configuration of your web server. The best way to get started is to use our `interactive guide <https://certbot.eff.org>`_. It generates instructions based on your configuration settings. In most cases, you’ll need `root or administrator access <https://certbot.eff.org/faq/#does-certbot-require-root-administrator-privileges>`_ to your web server to run Certbot.
+
+If you’re using a hosted service and don’t have direct access to your web server, you might not be able to use Certbot. Check with your hosting provider for documentation about uploading certificates or using certificates issued by Let’s Encrypt.
+
+Certbot is a fully-featured, extensible client for the Let's
+Encrypt CA (or any other CA that speaks the `ACME
+<https://github.com/ietf-wg-acme/acme/blob/master/draft-ietf-acme-acme.md>`_
+protocol) that can automate the tasks of obtaining certificates and
+configuring webservers to use them. This client runs on Unix-based operating
+systems.
+
+To see the changes made to Certbot between versions please refer to our
+`changelog <https://github.com/certbot/certbot/blob/master/CHANGELOG.md>`_.
+
+Until May 2016, Certbot was named simply ``letsencrypt`` or ``letsencrypt-auto``,
+depending on install method. Instructions on the Internet, and some pieces of the
+software, may still refer to this older name.

+
+Installation
+------------
+
+The easiest way to install Certbot is by visiting `certbot.eff.org`_, where you can
+find the correct installation instructions for many web server and OS combinations.
+For more information, see `Get Certbot <https://certbot.eff.org/docs/install.html>`_.
+
+.. _certbot.eff.org: https://certbot.eff.org/
+
+How to run the client
+---------------------
+
+In many cases, you can just run ``certbot-auto`` or ``certbot``, and the
+client will guide you through the process of obtaining and installing certs
+interactively.
+
+For full command line help, you can type::
+
+  ./certbot-auto --help all
+
+
+You can also tell it exactly what you want it to do from the command line.
+For instance, if you want to obtain a cert for ``example.com``,
+``www.example.com``, and ``other.example.net``, using the Apache plugin to both
+obtain and install the certs, you could do this::
+
+  ./certbot-auto --apache -d example.com -d www.example.com -d other.example.net
+
+(The first time you run the command, it will make an account, and ask for an
+email and agreement to the Let's Encrypt Subscriber Agreement; you can
+automate those with ``--email`` and ``--agree-tos``)
+
+If you want to use a webserver that doesn't have full plugin support yet, you
+can still use "standalone" or "webroot" plugins to obtain a certificate::
+
+  ./certbot-auto certonly --standalone --email admin@example.com -d example.com -d www.example.com -d other.example.net
+
+
+Understanding the client in more depth
+--------------------------------------
+
+To understand what the client is doing in detail, it's important to
+understand the way it uses plugins.  Please see the `explanation of
+plugins <https://certbot.eff.org/docs/using.html#plugins>`_ in
+the User Guide.

+Current Features
+=====================
+
+* Supports multiple web servers:
+
+  - apache/2.x
+  - nginx/0.8.48+
+  - webroot (adds files to webroot directories in order to prove control of
+    domains and obtain certs)
+  - standalone (runs its own simple webserver to prove you control a domain)
+  - other server software via `third party plugins <https://certbot.eff.org/docs/using.html#third-party-plugins>`_
+
+* The private key is generated locally on your system.
+* Can talk to the Let's Encrypt CA or optionally to other ACME
+  compliant services.
+* Can get domain-validated (DV) certificates.
+* Can revoke certificates.
+* Adjustable RSA key bit-length (2048 (default), 4096, ...).
+* Can optionally install a http -> https redirect, so your site effectively
+  runs https only (Apache only)
+* Fully automated.
+* Configuration changes are logged and can be reverted.
+* Supports an interactive text UI, or can be driven entirely from the
+  command line.
+* Free and Open Source Software, made with Python.
+
