 Certbot adheres to [Semantic Versioning](http://semver.org/).
 
-## 0.25.1 - 2018-06-13
-
-### Fixed
-
-* TLS-ALPN-01 support has been removed from our acme library. Using our current
-  dependencies, we are unable to provide a correct implementation of this
-  challenge so we decided to remove it from the library until we can provide
-  proper support.
-* Issues causing test failures when running the tests in the acme package with
-  pytest<3.0 has been resolved.
-* certbot-nginx now correctly depends on acme>=0.25.0.
-
-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:
-
-* acme
-* certbot-nginx
-
-More details about these changes can be found on our GitHub repo:
-https://github.com/certbot/certbot/milestone/56?closed=1
-
-## 0.25.0 - 2018-06-06
-
-### Added
-
-* Support for the ready status type was added to acme. Without this change,
-  Certbot and acme users will begin encountering errors when using Let's
-  Encrypt's ACMEv2 API starting on June 19th for the staging environment and
-  July 5th for production. See
-  https://community.letsencrypt.org/t/acmev2-order-ready-status/62866 for more
-  information.
-* Certbot now accepts the flag --reuse-key which will cause the same key to be
-  used in the certificate when the lineage is renewed rather than generating a
-  new key.
-* You can now add multiple email addresses to your ACME account with Certbot by
-  providing a comma separated list of emails to the --email flag.
-* Support for Let's Encrypt's upcoming TLS-ALPN-01 challenge was added to acme.
-  For more information, see
-  https://community.letsencrypt.org/t/tls-alpn-validation-method/63814/1.
-* acme now supports specifying the source address to bind to when sending
-  outgoing connections. You still cannot specify this address using Certbot.
-* If you run Certbot against Let's Encrypt's ACMEv2 staging server but don't
-  already have an account registered at that server URL, Certbot will
-  automatically reuse your staging account from Let's Encrypt's ACMEv1 endpoint
-  if it exists.
-* Interfaces were added to Certbot allowing plugins to be called at additional
-  points. The `GenericUpdater` interface allows plugins to perform actions
-  every time `certbot renew` is run, regardless of whether any certificates are
-  due for renewal, and the `RenewDeployer` interface allows plugins to perform
-  actions when a certificate is renewed. See `certbot.interfaces` for more
-  information.
-
-### Changed
-
-* When running Certbot with --dry-run and you don't already have a staging
-  account, the created account does not contain an email address even if one
-  was provided to avoid expiration emails from Let's Encrypt's staging server.
-* certbot-nginx does a better job of automatically detecting the location of
-  Nginx's configuration files when run on BSD based systems.
-* acme now requires and uses pytest when running tests with setuptools with
-  `python setup.py test`.
-* `certbot config_changes` no longer waits for user input before exiting.
-
-### Fixed
-
-* Misleading log output that caused users to think that Certbot's standalone
-  plugin failed to bind to a port when performing a challenge has been
-  corrected.
-* An issue where certbot-nginx would fail to enable HSTS if the server block
-  already had an `add_header` directive has been resolved.
-* certbot-nginx now does a better job detecting the server block to base the
-  configuration for TLS-SNI challenges on.
-
-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 functional changes were:
-
-* acme
-* certbot
-* certbot-apache
-* certbot-nginx

-
-## 0.24.0 - 2018-05-02
-
-### Added
-
-* certbot now has an enhance subcommand which allows you to configure security
-  enhancements like HTTP to HTTPS redirects, OCSP stapling, and HSTS without
-  reinstalling a certificate.
-* certbot-dns-rfc2136 now allows the user to specify the port to use to reach
-  the DNS server in its credentials file.
-* acme now parses the wildcard field included in authorizations so it can be
-  used by users of the library.
-
-### Changed
-
-* certbot-dns-route53 used to wait for each DNS update to propagate before
-  sending the next one, but now it sends all updates before waiting which
-  speeds up issuance for multiple domains dramatically.
-* Certbot's official Docker images are now based on Alpine Linux 3.7 rather
-  than 3.4 because 3.4 has reached its end-of-life.
-* We've doubled the time Certbot will spend polling authorizations before
-  timing out.
-* The level of the message logged when Certbot is being used with
-  non-standard paths warning that crontabs for renewal included in Certbot
-  packages from OS package managers may not work has been reduced. This stops
-  the message from being written to stderr every time `certbot renew` runs.
-
-### Fixed
-
-* certbot-auto now works with Python 3.6.
-
-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:
-
-* acme
-* certbot
-* certbot-apache
-* certbot-dns-digitalocean (only style improvements to tests)

-
-## 0.23.0 - 2018-04-04
-
-### Added
-
-* Support for OpenResty was added to the Nginx plugin.
-
-### Changed
-
-* The timestamps in Certbot's logfiles now use the system's local time zone
-  rather than UTC.
-* Certbot's DNS plugins that use Lexicon now rely on Lexicon>=2.2.1 to be able
-  to create and delete multiple TXT records on a single domain.
-* certbot-dns-google's test suite now works without an internet connection.
-
-### Fixed
-
-* Removed a small window that if during which an error occurred, Certbot
-  wouldn't clean up performed challenges.
-* The parameters `default` and `ipv6only` are now removed from `listen`
-  directives when creating a new server block in the Nginx plugin.
-* `server_name` directives enclosed in quotation marks in Nginx are now properly
-  supported.
-* Resolved an issue preventing the Apache plugin from starting Apache when it's
-  not currently running on RHEL and Gentoo based systems.
-
-Despite us having broken lockstep, we are continuing to release new versions of

-
-## 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.
-
-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:
-
-* acme
-* certbot
-
-More details about these changes can be found on our GitHub repo:
-https://github.com/certbot/certbot/milestone/51?closed=1
-
-## 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.

+
+    Please recall, that standard Python library implements
+    :class:`json.JSONEncoder` and :class:`json.JSONDecoder` that perform
+    translations based on respective :ref:`conversion tables
+    <conversion-table>` that look pretty much like the one below (for
+    complete tables see relevant Python documentation):
+
+    .. _conversion-table:
+
+    ======  ======
+     JSON   Python
+    ======  ======
+    object  dict
+    ...     ...
+    ======  ======
+
+    While the above **conversion table** is about translation of JSON
+    documents to/from the basic Python types only,
+    :class:`JSONDeSerializable` introduces the following two concepts:
+
+      serialization
+        Turning an arbitrary Python object into Python object that can
+        be encoded into a JSON document. **Full serialization** produces
+        a Python object composed of only basic types as required by the
+        :ref:`conversion table <conversion-table>`. **Partial
+        serialization** (accomplished by :meth:`to_partial_json`)
+        produces a Python object that might also be built from other
+        :class:`JSONDeSerializable` objects.
+
+      deserialization
+        Turning a decoded Python object (necessarily one of the basic
+        types as required by the :ref:`conversion table
+        <conversion-table>`) into an arbitrary Python object.
+
+    Serialization produces **serialized object** ("partially serialized
+    object" or "fully serialized object" for partial and full
+    serialization respectively) and deserialization produces
+    **deserialized object**, both usually denoted in the source code as
+    ``jobj``.
+
+    Wording in the official Python documentation might be confusing
+    after reading the above, but in the light of those definitions, one
+    can view :meth:`json.JSONDecoder.decode` as decoder and
+    deserializer of basic types, :meth:`json.JSONEncoder.default` as
+    serializer of basic types, :meth:`json.JSONEncoder.encode`  as
+    serializer and encoder of basic types.
+
+    One could extend :mod:`json` to support arbitrary object
+    (de)serialization either by:
+
+      - overriding :meth:`json.JSONDecoder.decode` and
+        :meth:`json.JSONEncoder.default` in subclasses
+
+      - or passing ``object_hook`` argument (or ``object_hook_pairs``)
+        to :func:`json.load`/:func:`json.loads` or ``default`` argument
+        for :func:`json.dump`/:func:`json.dumps`.
+
+    Interestingly, ``default`` is required to perform only partial
+    serialization, as :func:`json.dumps` applies ``default``
+    recursively. This is the idea behind making :meth:`to_partial_json`
+    produce only partial serialization, while providing custom
+    :meth:`json_dumps` that dumps with ``default`` set to
+    :meth:`json_dump_default`.
+
+    To make further documentation a bit more concrete, please, consider
+    the following imaginatory implementation example::
+
+      class Foo(JSONDeSerializable):
+          def to_partial_json(self):
+              return 'foo'
+
+          @classmethod

+          def to_partial_json(self):
+              return [Foo(), Foo()]
+
+          @classmethod
+          def from_json(cls, jobj):

+    def to_partial_json(self):  # pragma: no cover
+        """Partially serialize.
