Go: Network Edge Cases and a Compiler Reorganization
Three networking fixes tighten up connection lifecycle handling in HTTP and HTTP/2, while a long chain of compiler commits methodically splits the SSA package apart to enable parallel builds. Both threads share a common goal: closing gaps that only show up at the edges of connection teardown and package boundaries.

This is Go, your developer briefing for August 18th, 2026.
Today's activity has a clear throughline: careful cleanup of connection edge cases in the networking stack, alongside a major structural overhaul of the compiler's SSA package.
On the networking side, three separate fixes converge on the same theme: what happens at the boundaries of a connection's life. PR 80923 fixes HTTP/2 ping accounting, stopping the health-check timer when the read loop exits so a closed connection doesn't get falsely blamed for a lost ping, and doesn't get…
The second big theme is entirely internal: Michael Matloob's ongoing project, tracked under issue 80409, to break the compiler's SSA package into smaller pieces. Across roughly a dozen commits, code is being carved into an op package, a core package, and eventually a dedicated ssacompile package, all so…
Smaller but notable: PR 80932 enables ARM64 crypto feature detection on iOS, unlocking hardware-accelerated AES-GCM. And FIPS test infrastructure adopted a new ACVP key format for ML-DSA and ML-KEM testing.
What to remember: networking connection-close paths got real bug fixes this cycle, and the compiler internals are mid-refactor, so expect…
