Bump version to v12.5

* First take on 4.6 support

* improved docs

* Minor doc formattings

* added poll and poll_answer to filters

* added tests, fixed mentioned issues

* added poll_answer + poll filter tests

* Update docs according to official API docs

* introducing pollhandler and pollanswerhandler

* First take on 4.6 support

* improved docs

* Minor doc formattings

* added poll and poll_answer to filters

* added tests, fixed mentioned issues

* added poll_answer + poll filter tests

* Update docs according to official API docs

* introducing pollhandler and pollanswerhandler

* correct_option_id validated with None

when trying to send a poll with correct option id 0 it was failing. Now None check is done so that even when 0 is passed it is assigned.

* improving example

* improving code

* adding poll filter example to the pollbot.py

* Update Readme

* simplify pollbot.py and add some comments

* add tests for Poll(Answer)Handler

* We just want Filters.poll, not Filters.update.poll

* Make test_official fail again

* Handle ME.language in M._parse_*

 Another great way to start contributing is by writing tests. Tests are really important because they help prevent developers from accidentally breaking existing code, allowing them to build cool things faster. If you're interested in helping out, let the development team know by posting to the `developers' mailing list`_, and we'll help you get started.
 
+That being said, we want to mention that we are very hesistant about adding new requirements to our projects. If you intend to do this, please state this in an issue and get a verification from one of the maintainers.

+==============

+Version 12.4.1
+==============
+*Released 2020-02-08*
+
+This is a quick release for `#1744`_ which was accidently left out of v12.4.0 though mentioned in the
+release notes.
+
+
+Version 12.4.0
+==============
+*Released 2020-02-08*
+
+**New features:**
+
+- Set default values for arguments appearing repeatedly. We also have a `wiki page for the new defaults`_. (`#1490`_)
+- Store data in ``CallbackContext.bot_data`` to access it in every callback. Also persists. (`#1325`_)
+- ``Filters.poll`` allows only messages containing a poll (`#1673`_)
+
+**Major changes:**
+
+- ``Filters.text`` now accepts messages that start with a slash, because ``CommandHandler`` checks for ``MessageEntity.BOT_COMMAND`` since v12. This might lead to your MessageHandlers receiving more updates than before (`#1680`_).
+- ``Filters.command`` new checks for ``MessageEntity.BOT_COMMAND`` instead of just a leading slash. Also by ``Filters.command(False)`` you can now filters for messages containing a command `anywhere` in the text (`#1744`_).
+
+**Minor changes, CI improvements or bug fixes:**
+
+- Add ``disptacher`` argument to ``Updater`` to allow passing a customized ``Dispatcher`` (`#1484`_)
+- Add missing names for ``Filters`` (`#1632`_)
+- Documentation fixes (`#1624`_, `#1647`_, `#1669`_, `#1703`_, `#1718`_, `#1734`_, `#1740`_, `#1642`_, `#1739`_, `#1746`_)
+- CI improvements (`#1716`_, `#1731`_, `#1738`_, `#1748`_, `#1749`_, `#1750`_, `#1752`_)
+- Fix spelling issue for ``encode_conversations_to_json`` (`#1661`_)
+- Remove double assignement of ``Dispatcher.job_queue`` (`#1698`_)
+- Expose dispatcher as property for ``CallbackContext`` (`#1684`_)
+- Fix ``None`` check in ``JobQueue._put()`` (`#1707`_)
+- Log datetimes correctly in ``JobQueue`` (`#1714`_)
+- Fix false ``Message.link`` creation for private groups (`#1741`_)
+- Add option ``--with-upstream-urllib3`` to `setup.py` to allow using non-vendored version (`#1725`_)
+- Fix persistence for nested ``ConversationHandlers`` (`#1679`_)
+- Improve handling of non-decodable server responses (`#1623`_)
+- Fix download for files without ``file_path`` (`#1591`_)
+- test_webhook_invalid_posts is now considered flaky and retried on failure (`#1758`_)
