Good morning, it's June 11th, 2026. Yesterday brought significant compiler stability improvements and continued API evolution across the Go codebase.
The most critical theme was compiler correctness, with two important fixes from Jorropo addressing code generation issues. Commit f2f369d fixed a miscompilation bug in right-shift operations on ARM64, where a copy-paste error caused incorrect 64-bit comparisons for 32-bit shift amounts. A related fix in commit…
Security and networking saw meaningful enhancements. Roland Shoemaker's commit efbecbb added a LocalCertificate field to TLS ConnectionState, addressing a long-standing gap in certificate introspection capabilities that developers have requested since 2018. Meanwhile, commit 4093d5e from p4p3r fixed a subtle but…
API modernization continued with pull request 79943 updating OS package examples to use the modern errors.Is pattern instead of deprecated os.IsExist and os.IsNotExist functions. This reflects Go's ongoing shift toward more consistent error handling patterns. Joe Tsai contributed documentation improvements to the…
Runtime efficiency got attention through Keith Randall's optimization changing lock rank from int to int64,…
