The next major release of Emacs is going to be awesome, because among other things the so-called PureGTK work was also merged, which means that it will support HiDPI screens properly on Wayland.
Emacs 29 also aims to introduce experimental support for tree-sitter[1], although it will probably be hidden behind a configure-flag.
This should enable us to create better, faster parsers for popular languages where the Emacs-support so far has not been that great.
So yeah I second that. Emacs 29 is going to be a great release!
