Changelog Telegraf 4.0

General

• Port to TypeScript
• Update to Bot API 5.0
• Scenes now live in their own namespace called Scenes
• Allow cancelling requests via AbortController
• Add attachmentAgent option to provide an agent that is used for fetching files from the web before they are sent to Telegram (previously done through the same agent as used to connect to Telegram itself)

Apart from updating Telegraf to full Telegram Bot API 5.0 support, the most significant improvement is that we now have a code base that is written 100 % in TypeScript, which more or less required a rewrite of the complete library. Previously, the library was written in JavaScript and had a few type annotations to the side, but they were often incorrect or missing.

In working on the 4.0 release, we created type coverage of the complete Telegram Bot API. The benefit is that your editor can now autocomplete accross every single field in every single method or entity. Those who ever tried it out can confirm that this improves the development experience by an order of magnitude.

Note that this update brings 9 months worth of improvements, so while we did our best to summarise all important changes, it's possible that we forgot some!

Composer

• Add Composer.guard
• Deprecate static Composer.mount, prefer static Composer.on
• Make Composer.entity and Composer.match private
• Remove Composer.catchAll and Composer.safePassThru
• Catch errors of both branches of Composer.fork
• Listen to forwards using on('forward_date'), no longer on('forward')

Context

• Make ctx.botInfo required, i.e. is is always available
• Make ctx.state readonly
• Add ctx.senderChat, ctx.unpinAllChatMessages, and ctx.copyMessage
• ctx.deleteMessage no longer works for edited messages, channel posts, or edited channel posts
• Remove ctx.updateSubTypes

Extra

Extra is removed entirely, see #1076.
