Go accepts runtime/mainthread package for main-thread work
🐿️ GoDaily - October 16, 2026
The Go team has accepted the long-running proposal for a new runtime/mainthread package, giving GUI and other platform code a sanctioned way to pin work to the main OS thread instead of hand-rolling it on top of LockOSThread.
