Release / 7 Jan 2026 / with v2.2.0

mason.nvim v2.2.1

Keep managing installed tools after their packages disappear from a registry.

What changed in v2.2.1

Installed packages missing from registries remain discoverable through their receipts, with removal notices. Installation finalization recovers from a known directory-rename failure on some filesystems.

Install mason.nvim v2.2.1 with a Neovim plugin manager and call `require("mason").setup()`. Requires Neovim 0.10+ and package-specific external tools.
