> I would like to propose the following plan for the 22.1 release.
>
> I will roll the 22.0.98 pretest tarball on Monday, April 16 (8 days

> problem arises.

> If no major problems with the April 16 pretest come to light, we
> should cut the Emacs 22 CVS branch on Friday, April 20, and release
> Emacs 22.1 on Monday, April 23.

22.1がstableリリースのことだとすると
何も問題なければ23日に出るみたい？
