What happened
Emacs 31.1 is released with quality-of-life improvements rather than a single headline feature. Notable changes include retiring the legacy unexec dumper in favor of pdumper, a tree-sitter grammar auto-installer, and general refinements; the planned new garbage collector was postponed to Emacs 32.
Why it matters
If you use Emacs as your daily editor, the tree-sitter grammar auto-installer removes a manual setup step, and the full retirement of unexec means you should verify your config still works with pdumper. For everyone else, this is a routine release with no actionable impact.
Discussion angle
Whether tree-sitter's auto-installer makes Emacs a more viable option for developers who left it due to configuration friction.
