WordPress 6.1 Beta 1 was originally scheduled to be released today (Tuesday, September 20th) starting at 16:00 UTC. However, during the release party in #core those assembled identified an NPM test failure and three Gutenberg PRs (#3221, #3254, #3255) that were included in the 6.1 Walkthrough and were all deemed ideally resolved and properly part of the 6.1 Beta 1 release.
The decision was made to delay the 6.1 Beta 1 release party to tomorrow, Wednesday, September 21st at 16:00 UTC to allow time to resolve the NPM test failure and wrap up reviews and commits on the Gutenberg PRs.
The rest of the 6.1 release cycle schedule is unchanged.
