GOPLS V0.23.0 SHIPS AS GO TOOLCHAIN FIXES PLAN 9 COMPATIBILITY

By RepoJournal ยท Filed ยท About Go

gopls 0.23.0 landed overnight while the Go core team fixes a Plan 9 regression in file removal that could break deployments on legacy systems.

gopls v0.23.0 is out [1], closing the gap on tooling improvements across the ecosystem. The release lands as golang/go addresses a critical Plan 9 compatibility issue where RemoveAll fails to strip trailing slashes on non-directory paths [2], a regression that breaks cleanup operations on Plan 9 systems. On the analyzer front, the tools team added a new reflecttypeassert modernizer that suggests replacing two-valued type assertions with reflect.TypeAssert from go1.25, avoiding intermediate allocations [3]. Meanwhile, the build infrastructure tightened resource allocations for the coordinator, capping it at 1 CPU and 1GB based on actual usage patterns [4], while vulndb cut test time roughly in half by switching to cached-only modproxy endpoints [5]. All three repos (go, build, tools, vulndb) updated their golang.org/x dependencies to latest tagged versions [ref:8, ref:15].
