Go 1.26 Release Party Scheduled for February 19

Go 1.26 was released February 10, 2026, bringing language improvements including new expression support for the built-in new() function, post-quantum cryptography support, and performance gains from the Green Tea garbage collector.

The Go programming language released version 1.26 on February 10, 2026, six months after Go 1.25. JetBrains is hosting a livestream release party on February 19 to celebrate and explore the new features with the Go community.

Language and Standard Library Enhancements

Go 1.26 introduces two significant language refinements. The most notable change allows developers to pass expressions directly to the built-in new() function, simplifying memory allocation patterns. The standard library gained three new packages, including crypto/hpke for Hybrid Public Key Encryption as specified in RFC 9180, with support for post-quantum hybrid KEMs. An experimental runtime/secret package provides facilities for securely erasing temporaries used in cryptographic code.

Performance Improvements

The experimental Green Tea garbage collector that debuted in Go 1.25 is now enabled by default, delivering dramatically faster memory allocation for small objects. This change should improve performance for many Go applications without requiring code changes. An experimental simd/archsimd package, enabled via GOEXPERIMENT=simd at build time, provides access to architecture-specific SIMD operations for performance-critical code.

Platform Support Changes

Go 1.26 is the final release supporting macOS 12 Monterey. Go 1.27 and later versions will require macOS 13 Ventura or newer. This follows Go's policy of supporting the three most recent major macOS releases. Developers still using Monterey should plan their migration before upgrading to Go 1.27.
