The next claudecode.nvim release. Merging this PR creates the release tag and GitHub Release, then starts Communique GitHub Release note generation.

[0.5.0] - 2026-11-14

Added

• Set the claudecode filetype on the Claude terminal buffer (native and snacks), so autocmds can target it (#202, @ehaynes99)
• <C-z> in the Claude terminal now suspends Neovim instead of suspending Claude Code, matching Ctrl-Z in any other window (#448)

Changed

• The unified diff layout now officially runs on Neovim 0.8.0 (it only needs vim.diff); the "requires Neovim >= 0.9.0" note has been dropped (#564)
• @mentions are now sent as absolute paths, matching the official VS Code extension and resolving correctly when Claude's working directory differs from Neovim's (#460)
• An invalid terminal.provider value now keeps the previously configured provider and the warning names it accurately (Keeping 'auto'.) instead of falsely claiming it defaulted to native (#530)

Fixed

• :ClaudeCodeAdd % now works for buffers whose path contains spaces (#304, @joshmedeski)
• Queued @mentions are now delivered once, in order, or report an error; a mention queued while Claude is launching is delivered once Claude connects even if startup is slow (#454)
• A send with disable_broadcast_debouncing = true now waits for the connection readiness window instead of reaching Claude mid-startup (#541)
• Terminal lifecycle hardening: keep a single live Claude, never run a second one, never close the wrong window, and no longer error with E444 when Claude's window is the only one (#451)
• Reuse the :tabnew window for the unified new-tab diff, removing the stray empty pane and fixing new-tab cleanup (#303, @zakissimo)
• Diff accept now returns the exact proposed bytes: keep trailing blank lines in a unified diff (#535), accept proposals without a final line break in the split layouts (#542), save an emptied buffer as an empty string (#551), and save CRLF proposals with CRLF line endings (#577)
• getCurrentSelection answers from the live editor when no selection is tracked, and from the previous window when the Claude terminal is current (#457, #463)
• Held selections end correctly when their text or cursor changes, and are no longer leaked across file changes or the Claude terminal (#452, #471, #481, #493, #524, #540, #562)
• Malformed tools/call and close_tab requests now get proper JSON-RPC -32602 "Invalid params" errors instead of internal error text or leaked file paths (#497, #500)
• saveDocument reports only the Vim error (e.g. E45: 'readonly' option is set) instead of a full Lua stack trace with install paths (#453)
• openFile finishes reloading a file even when a user's BufReadPre/FileChangedShell autocmd errors, so the buffer holds the new content and a later :w doesn't silently overwrite Claude's file (#461, #468)
• WebSocket server reliability: never time out a live Claude, drop dead or silent clients promptly, and hold disconnect cleanup until window changes are allowed (#455, #467, #479, #488, #499)
• The Claude terminal working directory is found and used correctly for folders whose names contain spaces, commas, $, \, brackets, or other path characters (#561, #569)
• Lock file handling reports failed removals and cleans up on token mismatch, so a stale auth token is never silently left on disk (#459, #557)
• Extensive diff lifecycle hardening: clean teardown after :wq, :q, :qa, :edit, and a second :w; preserve the sign column and diff mode in windows a closed diff leaves; hide a floating Claude terminal only while a diff is open in its tab; answer every open diff when Neovim exits; and keep Neovim alive when a user handler raises during diff setup (#469, #473, #478, #483, #491, #494, #504, #511, #516, #538, #558, #574)
