Nicolas Petton writes that the emacs-26.1.91, the second pretest for emacs 26.2, is out. I compiled and installed it last night and am using it as my working Emacs. I have less than a day’s experience with it so far but I haven’t run across any problems.
If you’re running macOS 10.14 (Mojave) you’re probably already using the first pretest because of the display problems that Mojave introduced. There’s no reason not to upgrade to 26.1.91—I renamed my old version so I can drop back to it if disaster strikes. If you’re not a Mac user, you should still try it out if you can. Your experience with it and any problems you find will help the developers in getting 26.2 out the door.
As usual, thanks to Nico, Eli, John, and all the others for all the hard work they do on our behalf.
