*Released 2020-02-08*

This is a quick release for :pr:`1744` which was accidently left out of v12.4.0 though mentioned in the
release notes.

==============
*Released 2020-02-08*

**New features:**

- Set default values for arguments appearing repeatedly. We also have a `wiki page for the new defaults`_. (:pr:`1490`)
- Store data in ``CallbackContext.bot_data`` to access it in every callback. Also persists. (:pr:`1325`)
- ``Filters.poll`` allows only messages containing a poll (:pr:`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 (:pr:`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 (:pr:`1744`).

- Add option ``--with-upstream-urllib3`` to `setup.py` to allow using non-vendored version (:pr:`1725`)
- Fix persistence for nested ``ConversationHandlers`` (:pr:`1679`)
- Improve handling of non-decodable server responses (:pr:`1623`)
- Fix download for files without ``file_path`` (:pr:`1591`)
