- Pyrogram core is now fully asynchronous - Ditched Python 3.5, welcome 3.6 as minimum version. - Moved all types to pyrogram.types - Turned the Filters class into a module (filters) - Moved all filters to pyrogram.filters - Moved all handlers to pyrogram.handlers - Moved all emoji to pyrogram.emoji - Renamed pyrogram.api to pyrogram.raw - Clock is now synced with server's time - Telegram schema updated to Layer 117 - Greatly improved the TL compiler (proper type-constructor hierarchy) - Added "do not edit" warning in generated files - Crypto parts are executed in a thread pool to avoid blocking the event loop - idle() is now a separate function (it doesn't deal with Client instances) - Async storage, async filters and async progress callback (optional, can be sync too) - Added getpass back, for hidden password inputs
