Go 1.26 introduces significant language and runtime improvements. Key features include `new(expr)` for creating pointers from expressions, type-safe error checking with `errors.AsType`, the Green Tea garbage collector for better memory efficiency on multi-core systems, faster cgo/syscalls and memory allocation, experimental SIMD operations, secret mode for cryptographic data protection, goroutine leak profiling, and numerous standard library enhancements including reflective iterators, buffer peeking, process handles, and improved metrics.
