GOPLS 0.22.0 SHIPS WITH INTERACTIVE REFACTORING, CRYPTO DROPS LEGACY ASSEMBLY

By RepoJournal · Filed · About Go · Composed from the cited sources · methodology

Go's language server reached a major milestone overnight with v0.22.0, unlocking interactive refactoring across the ecosystem while the crypto package aggressively modernizes its CPU instruction set.

Gopls v0.22.0 [1] landed with interactive refactoring support, the feature teams have been waiting for since it was proposed in golang/go#76331. VSCode-Go already updated to track the release [2], and the infrastructure is moving beyond LSP customization toward native language client capabilities [3]. On the crypto front, the team removed pre-AVX assembly implementations from chacha20poly1305 [4] and cleaned up legacy BYTE instruction usage [5], pushing minimum CPU requirements up to AVX-era hardware. This is a hard break from pre-2013 processors, but it simplifies the codebase and unlocks better performance on modern systems. Inside the runtime, Go's allocator is getting refactored for clarity [6] while math/big optimization work continues [7]. The pkg.go.dev API fixed a critical scheme detection bug that was breaking documentation fetches [8], and the tools team patched an interpreter panic in ssadump [9]. Quiet refactoring week overall, but two solid wins that ship real capability.
