As mentioned in the prior status, the channel limit was raised from 100 to 200.
In the near future a retention limit will be set so you can still go back and reinstate a channel you had deleted. Once the retention period has expired then the channel will get a hard delete which will free up the space and no longer count toward the 200 channel limit.
This will help with some of the issues you have voiced in the comments below.
But I understand many of you wish the limit to be further increased. I will continue to provide your votes and comments to the feature team.
This item is still on the backlog. I’ve received no further updates yet about this topic. I will continue to bring your feedback to the feature team.

MS Teams recently stopped automatically appending the bot's @mention when replying the bot's messages. This just became a major block, since now the user has to manually mention the bot on every reply to its messages. This feature is being specified on this document and it's not working anymore:
"Note: For convenience when replying to bot messages in a channel, the bot name is prepended in the compose message box automatically."
