Invoke Emacs with the '-seccomp=FILE' command-line option. This is supported only on capable GNU/Linux systems. Emacs now supports loading a Secure Computing filter. I don’t know if I’ve ever been a victim of this issue, but my kill-emacs-hook variable has about a dozen different hooked functions, many of them complex (tramp, lsp, etc.) - so I can imagine this is likely to silently benefit people who’d otherwise wonder why their Emacs won’t exit properly. If the user doesn'tĪnswer within five seconds, Emacs will continue shutting down anyway. The user will be prompted on whether to continue. If a function in that hook signals an error in an interactive Emacs, Errors in 'kill-emacs-hook' no longer prevent Emacs from shutting down. I’ve never noticed that problem with Emacs myself, but I can definitely think of lots of other applications that do do that, and it’s very annoying. (when started via the Desktop) if the user is typing into another This means that Emacs won't steal keyboard focus upon startup Onwards with the NEWS commentary! Startup Changes in Emacs 28.1 In GTK builds, Emacs now supports startup notification. Notable features include the formal inclusion of native compilation, a technique that will greatly speed up your Emacs experience.Ī critical issue surrounding the use of ligatures also fixed without it, you couldn’t use ligatures in Emacs 27 without crashes. It’s that time again: there’s a new major version of Emacs and, with it, a treasure trove of new features and changes.
