Filters are no longer callable, if you're using a custom filter and are calling an existing filter, then switch to the new syntax: ``filters.{filter}.check_update(update)``. #. Removed the ``Filters`` class. The filters are now directly attributes/classes of the :mod:`~telegram.ext.filters` module. #. The names of all filters has been updated: * Filter classes which are ready for use, e.g ``Filters.all`` are now capitalized, e.g ``filters.ALL``. * Filters which need to be initialized are now in CamelCase. E.g. ``filters.User(...)``. * Filters which do both (like ``Filters.text``) are now split as ready-to-use version ``filters.TEXT`` and class version ``filters.Text(...)``.
