The first release candidate for Emacs 30.1, the extensible text editor, is now available at:
https://alpha.gnu.org/gnu/emacs/pretest/emacs-30.1-rc1.tar.xz
Please give it as much testing as you can. If no problems are reported, this will become Emacs 30.1 this Sunday.
Emacs 30 is a more low-key release compared to heavy hitting features like native compilation in 28 and Tree-sitter in 29. Probably the headline change is replacing the libjansson based JSON parser with a homegrown one that is several times (~8x) faster, which will significantly benefit features like LSP. This will also mark the official release of the Android port, as well as the usual scattershot of improvements across the board. The NEWS file has the full changelog.
The most anticipated feature for me is the native support to install packages from vc repositories instead of just from package repos
