Version 12.0.0
================
*Released 2019-08-29*

Well... This felt like decades. But here we are with a new release.

Expect minor releases soon (mainly complete Bot API 4.4 support)

**Major and/or breaking changes:**

- Context based callbacks
- Persistence
- PrefixHandler added (Handler overhaul)
- Deprecation of RegexHandler and edited_messages, channel_post, etc. arguments (Filter overhaul)
- Various ConversationHandler changes and fixes
- Bot API 4.1, 4.2, 4.3 support
- Python 3.4 is no longer supported
- Error Handler now handles all types of exceptions (`#1485`_)
- Return UTC from from_timestamp() (`#1485`_)

**See the wiki page at https://github.com/python-telegram-bot/python-telegram-bot/wiki/Transition-guide-to-Version-12.0 for a detailed guide on how to migrate from version 11 to version 12.**

Context based callbacks (`#1100`_)
----------------------------------

- Use of ``pass_`` in handlers is deprecated.
- Instead use ``use_context=True`` on ``Updater`` or ``Dispatcher`` and change callback from (bot, update, others...) to (update, context).
- This also applies to error handlers ``Dispatcher.add_error_handler`` and JobQueue jobs (change (bot, job) to (context) here).
- For users with custom handlers subclassing Handler, this is mostly backwards compatible, but to use the new context based callbacks you need to implement the new collect_additional_context method.
- Passing bot to ``JobQueue.__init__`` is deprecated. Use JobQueue.set_dispatcher with a dispatcher instead.
- Dispatcher makes sure to use a single `CallbackContext` for a entire update. This means that if an update is handled by multiple handlers (by using the group argument), you can add custom arguments to the `CallbackContext` in a lower group handler and use it in higher group handler. NOTE: Never use with @run_async, see docs for more info. (`#1283`_)
- If you have custom handlers they will need to be updated to support the changes in this release.
- Update all examples to use context based callbacks.

Persistence (`#1017`_)
----------------------

- Added PicklePersistence and DictPersistence for adding persistence to your bots.
- BasePersistence can be subclassed for all your persistence needs.
- Add a new example that shows a persistent ConversationHandler bot

Handler overhaul (`#1114`_)
---------------------------

- CommandHandler now only triggers on actual commands as defined by telegram servers (everything that the clients mark as a tabable link).
- PrefixHandler can be used if you need to trigger on prefixes (like all messages starting with a "/" (old CommandHandler behaviour) or even custom prefixes like "#" or "!").

Filter overhaul (`#1221`_)
--------------------------

- RegexHandler is deprecated and should be replaced with a MessageHandler with a regex filter.
- Use update filters to filter update types instead of arguments (message_updates, channel_post_updates and edited_updates) on the handlers.
- Completely remove allow_edited argument - it has been deprecated for a while.
- data_filters now exist which allows filters that return data into the callback function. This is how the regex filter is implemented.
- All this means that it no longer possible to use a list of filters in a handler. Use bitwise operators instead!

ConversationHandler
-------------------

- Remove ``run_async_timeout`` and ``timed_out_behavior`` arguments (`#1344`_)
- Replace with ``WAITING`` constant and behavior from states (`#1344`_)
- Only emit one warning for multiple CallbackQueryHandlers in a ConversationHandler (`#1319`_)
- Use warnings.warn for ConversationHandler warnings (`#1343`_)
- Fix unresolvable promises (`#1270`_)


Bug fixes & improvements
------------------------

- Handlers should be faster due to deduped logic.
- Avoid compiling compiled regex in regex filter. (`#1314`_)
- Add missing ``left_chat_member`` to Message.MESSAGE_TYPES (`#1336`_)
- Make custom timeouts actually work properly (`#1330`_)
- Add convenience classmethods (from_button, from_row and from_column) to InlineKeyboardMarkup
- Small typo fix in setup.py (`#1306`_)
- Add Conflict error (HTTP error code 409) (`#1154`_)

- Fix send_location() - latitude may be 0 (`#1437`_)

Fully support Bot API version 4.0!
(also some bugfixes :))

Telegram Passport (`#1174`_):

- Add full support for telegram passport.
    - New types: PassportData, PassportFile, EncryptedPassportElement, EncryptedCredentials, PassportElementError, PassportElementErrorDataField, PassportElementErrorFrontSide, PassportElementErrorReverseSide, PassportElementErrorSelfie, PassportElementErrorFile and PassportElementErrorFiles.
