That was speedy. After only two weeks since the release of the Emacs-27.1-RC1, the final 27.1 is available. I’m happy to say that this post is being written with it and I haven’t experienced any problems at all.
There’s a bunch of new changes—all documented in the NEWS file—but what I like the most is that Emacs Lisp finally has arbitrary precision integers. Your favorite new feature will probably differ.
As usual, thanks the Eli, John, Nico, and all the other developers who made this possible. These guys are really heroes, doing a lot of hard work for no pay. If you meet one of them IRL, be sure to buy them a beer.
