What's new in Emacs 29.1
I&#x27;m not really happy with the number of times I have recently had to resort to sending it SIGUSR2 to force it to stop whatever it&#x27;s doing when I re-indent some code in a file of Typescript.  It happens about once a day.  When it does I quickly save all my work and restart.  I haven&#x27;t looked too closely at it yet but from what I&#x27;ve seen in backtraces I suspect there&#x27;s a bad pattern match situation in there somewhere, like what you might get from the exponential behavior of a poorly written regex.<p>I&#x27;m also not happy about the fact that I can no longer open large C++ files like <a href="https:&#x2F;&#x2F;github.com&#x2F;ASDAlexander77&#x2F;TypeScriptCompiler&#x2F;blob&#x2F;main&#x2F;tsc&#x2F;lib&#x2F;TypeScript&#x2F;MLIRGen.cpp">https:&#x2F;&#x2F;github.com&#x2F;ASDAlexander77&#x2F;TypeScriptCompiler&#x2F;blob&#x2F;ma...</a> in C++ mode without scrolling becoming so sluggish as to be unusable.  I either have to disable C++ mode or open them in an older version.<p>It&#x27;s good that emacs is getting some long needed attention, but I&#x27;m sad the latest version isn&#x27;t as usable for me.
