Emacs 28.2 is a bug-fix release, with no new features with respect to Emacs 28.1.

Must be a slow news day on HN, huh...

I don’t use Emacs these days but I still enjoy keeping up with it.

The performance issues with elisp keep it from “conquering” more of the world.

I expect to wake up one morning and read on HN that they’ve finally fixed it.

Then the Ultimate Editor Construction Kit will win over another generation.

I'm not an emacs user, but it's interesting to look at the sort of changes going into a program that was originally written in 1981 (Gosling Emacs, the basis for Stallman's Emacs).

There's not many other programs that are in a similar place of very old + still in widespread use + still seeing regular feature development.

The impacts of what sort of design decisions linger on, and for how long? What change is born out of the program itself vs. having to adapt to changes in the environment? What's more likely to result in defect counts going up again? All sorts of interesting data points re lifecycle ...

One recent change I cannot value high enough is optimizations which went into dealing with long lines. If you remember Emacs as being unusable as an editor for long lines, this is no more. I don't know if this went into 28.2 as I am happily using 29.0.50

Are we talking about real optimizations? I remember some years ago (with v27.1?) there were some solution for long lines introduced which basically came down to just deactivating certain features like fontlock, etc.

Are we talking about real optimizations?

Yes. The new fixes don't work by turning off features like so-long-mode does. And they remove the long lines penalty almost completely.

No, this will be part of Emacs 29.1, the changes part of 28.2 are relativly minor: https://git.savannah.gnu.org/cgit/emacs.git/tree/etc/NEWS?h=...
