Go just got faster..

Go 1.25, expected in August 2025, introduces several performance improvements including the experimental Green Tea garbage collector promising 10-40% reduction in GC overhead, a new JSON v2 package that's 2.7-21x faster than the current implementation, DWARF version 5 debug information for faster compilation, and enhanced address sanitizer with leak detection. These features are currently experimental and require build-time flags to enable.
