Audacity Forum

And that now there are no messages on the e-mail about the release of the new version of Audacity? I didn't receive. Is it necessary to check for updates? Not always convenient.

In Audacity. "Help menu > Check for Updates".

Updates are also announced on social media:
facebook: https://www.facebook.com/AudacityTeamOfficial/
twitter: https://twitter.com/getaudacity
G+ https://plus.google.com/+audacity

and the Audacity website: https://www.audacityteam.org/

and here on the forum.

Thank you! And will there be nightly builds of alpha 2.2.2?

At present there are nightly builds for macOS https://www.fosshub.com/Audacity-Mac-Nightlies.html
Hopefully there will be nightly builds for Windows in the future, and some AppImage builds for Linux (https://github.com/probonopd/audacity/releases)
