Good morning, this is your Go weekly recap for April 13th through 20th, 2026.
Zero pull requests were merged this week, with 30 additional commits landing across the main repository.
Starting with networking infrastructure, Damien Neil made substantial changes to HTTP/2 handling. The net/http package now supports x/net/http2 Transport wrapping, allowing the HTTP/2 transport to be implemented in terms of a standard HTTP transport. This includes new methods for configuration queries and connection…
In compiler improvements, Rob Findley fixed a critical issue in the type system where instantiated generic types weren't properly substituting receiver type arguments into method type parameter bounds. This resolves errors where method calls on generic types were incorrectly rejected due to unresolved type references.
SIMD and assembly optimizations received significant attention from Junyang Shao. Multiple commits improved AVX instruction selection, including fixes for VPEXTR operations on 8 and 16-bit elements and proper AVX variant selection for VPSHUF operations on 128-bit vectors. ARM64 assembly support was also enhanced…
Platform-specific updates include Meng Zhuo's addition of vector…
