Neovim 0.12.0 (released March 29, 2026) brings major built-in improvements that reduce reliance on third-party plugins. Key additions include: vim.pack, a built-in experimental plugin manager with lockfile support; native insert-mode auto-completion via the new 'autocomplete' option; expanded LSP capabilities (selectionRange, inlineCompletion, linkedEditingRange, viewport-only semantic tokens); a redesigned experimental UI (ui2); built-in plugins like :Undotree and :DiffTool; new Lua APIs including vim.net.request() and vim.fs.ext(); and new editor commands like :restart and :connect. Breaking changes include diagnostic signs now requiring vim.diagnostic.config(), removal of vim.diagnostic.disable(), changed behavior of vim.treesitter.get_parser(), and Insert-mode Ctrl-R now inserting register contents literally. A migration checklist and practical config examples are provided.
