https://www.nuget.org/packages/Telegram.Bot/#versions-body-tab! Big release! 😲

https://telegrambots.github.io/book/migrate/Version-22.x.html#whats-new-in-version-225:
- Support for https://t.me/BotNews (lots of new stuff)
- Removed the *Async-suffixed versions of the methods that were https://telegrambots.github.io/book/migrate/Version-22.x.html#-how-to-adapt-your-code-for-these-changes.
- Services. ConfigureTelegramBot* is no longer necessary to make your Webhook bot compatible with Telegram updates!
In some rare cases (like https://learn.microsoft.com/en-us/dotnet/core/deploying/native-aot / https://learn.microsoft.com/en-us/aspnet/core/blazor/webassembly-build-tools-and-aot / https://learn.microsoft.com/en-us/dotnet/core/deploying/trimming/trim-self-contained), this call might still be necessary.
- Removed dependency on http://ASP.NET/ Core (Microsoft. AspNetCore. App) from the main library, by moving the ConfigureTelegramBotMvc() method to a separate package https://www.nuget.org/packages/Telegram.Bot.AspNetCore
→ That dependency caused some issues for users deploying to Docker / Android / WebAssembly
- Merged (and updated) the Telegram. Bot. Extensions. Passport package into the main library
- New HtmlText helpers method: ToPlain, PlainLength and Truncate to get the plain text only from HTML text (remove the ), the number of plain text characters, or truncate the HTML to a number of plain text characters (useful to comply with the 4096/1024 message limit)
- Added constructor ChatAdministratorRights(bool) to set all fields to true or false (except IsAnonymous)
- Added helper property message. IsServiceMessage to detect service messages vs content messages
- Added helper property ChatMemberRestricted. IsMuted to detect if restriction is muting the user (v22.5.1)

Builds & Releases:
- Dropped Azure DevOps builds in favor of GitHub Actions
→ Our https://dev.azure.com/tgbots/Telegram.Bot/_artifacts/feed/release will no longer be updated since we are https://www.nuget.org/packages/Telegram.Bot/#versions-body-tab
- "Prerelease" versions are now pushed to https://www.nuget.org/packages/Telegram.Bot/absoluteLatest#versions-body-tab as the library is developed. Useful for people who want to test upcoming features early
→ You can provide feedback on these versions and help us detect problems before the next stable release
- Now including Release Notes as part of Nuget packages
→ You can see them on https://www.nuget.org/packages/Telegram.Bot/#releasenotes-body-tab, or in your IDE's Package Manager, on the Package Detail pane where you select a version.

2 small breaking changes:
- Merged AnswerShippingQuery method overloads. You'll need to add errorMessage: in your code to pass that argument and indicate failure.
- The Poll. Type is now an enum PollType instead of string

- Added constructor ChatPermissions(bool) to set all fields to true or false
- Fix a potential issue in . ToHtml() escaping & in URLs

- InlineKeyboardButton can be implicitly constructed from a (text, callbackOrUrl) tuple for Callback or Url buttons (v22.4.1)

https://www.nuget.org/packages/Telegram.Bot/#versions-body-tab on Nuget!

What's new:
- Support for https://core.telegram.org/bots/api#january-1-2025
- Renamed class Telegram. Bot. Types. File as TGFile
(the name File was annoyingly conflicting with the often-used System. IO. File class)
- Added property Token to TelegramBotClient
(you can use it to ParseValidateData MiniApp requests, authenticate WebHook updates, ...)

Note: we didn't add it to ITelegramBotClient to limit this "secret" from being leaked when sharing bot as interface.

🎉 Telegram. Bot https://www.nuget.org/packages/Telegram.Bot/#versions-body-tab ON NUGET․ORG !

https://telegrambots.github.io/book/migrate/Version-22.x.html#whats-new-in-version-2200:
- Support for https://core.telegram.org/bots/api-changelog#october-31-2024
- Implicit conversions for single-field structures
- Implicit conversion from FileBase classes to InputFile
- Helper method GetFileIdType
- Huge rewrite of our serialization code to make it more performant and straightforward.
- Updated STJ due to vulnerability https://github.com/advisories/GHSA-8g4q-xg66-9fp4
- Fix: allowPaidBroadcast support (v22.0.1)

https://telegrambots.github.io/book/migrate/Version-22.x.html#-breaking-changes:
As previously announced, we renamed most methods by removing the Async suffix and reordered a few arguments to place useful ones near the start of parameters list.
👉 For the moment, we still support the old methods, they will produce "Obsolete method" compiler warnings but your existing code should work fine.

https://telegrambots.github.io/book/migrate/Version-22.x.html#-how-to-adapt-your-code-for-these-changes:
With just 4 Find & Replace operations, you should be able to modify your code for v22.* and make these warnings go away.

ℹ️ Announcement ℹ️

As you know, since I took the development lead of this library, I'm particularly attached to making developers' life simpler by adding helpers class, implicit conversions, ensuring better compatibility for legacy code, avoiding breaking code, providing smooth migration paths, better documentation and fast upgrades for new Bot API...

However, when comes the time for the next Bot API version, we will be switching from v21.* to v22 because there will be two major breaking changes:

1) We will be removing the "Async" suffix at the end of all our method names
Our library is fully asynchronous, so it is obvious our API methods should be awaited. There is no mix with non-async methods here. The suffix just makes the names longer unnecessarily and mismatch with the method names from official https://core.telegram.org/bots/api#available-methods.

2) We will do a limited reordering of a few optional parameters (with no change to argument names)
The aim is to move the lesser used method arguments later down the argument list (typically: message_thread_id/entities)
and move the more useful arguments up closer to the beginning (typically: replyParameters/replyMarkup)
For new code, this should make your life simpler as you won't need to resort to https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/named-and-optional-arguments#named-arguments for the most commonly used method parameters.

Of course, in order to mitigate the burden of adapting your code, the old method names & their parameter order will still be included for several months, marked as [Obsolete] and routing to the new methods.
Our documentation page for migrating to v22 will also include tips to help you port existing code to the new methods.

As much as I hated all the breaking changes that kept happening with this library prior to v21, I will make sure this kind of major breaking change stays a one-time thing and won't happen anymore.

— Your friend in time, Wizou

https://t.me/WTelegramBot Introducing https://t.me/WTelegramBot (the bot, not the library)

This https://core.telegram.org/bots/inline has a lot of answers to bot programming questions, with link to documentation and examples.
It also contains description/parameters for every Bot API method.
(it will be continuously improved as I see new articles or information to add)

Just type @WTelegramBot followed by a small number of keywords/topics related to your question.
For example, try: @WTelegramBot chat

The bot will show you a list of possible articles matching your topic, and you can click on one to post the full article in the current chat.

You may use it:
- in private chat with the bot
- in https://t.me/joinchat (to help answer other people)
- or in any chat you want
