- Use markdown in media captions
(**bold**, __italic__, `tag` and ```code```).
- Use emoji replacement in media captions,
group and channel titles and descriptions (:like: etc.)
- Markdown replacement now happens immediately
after typing (instead of after sending) and can be
rolled back using Backspace or Ctrl/Cmd + Z.
Replacement no longer happens when pasting text.
