Release v0.5.2 · ChuYanLon/telegram.nvim

[0.5.2] - 2026-06-03

Message window capped at 200 — state.messages no longer grows unbounded; trimmed on scroll and new message arrival to prevent long-session lag
CursorMoved handler debounced — O(n) message scan and pagination trigger deferred to 50ms after last cursor movement, eliminating jank on rapid scrolling
curl_with_retry timeouts reduced — retries 4→2, max-time 15s→5s, connect-timeout 5s→2s for faster failure recovery
Chat title update debounced — VimResized/WinScrolled no longer share the same augroup (VimResized was silently dropped)
close_chat non-blocking — replaced synchronous vim.fn.system("curl") with fire-and-forget request_async, preventing exit freeze
Timer leaks fixed — refresh_timer, _scroll_timer, _typing_timer, _title_update_timer now properly stopped in destroy_chat, logout, and VimLeavePre
_edit_ts stale entries cleaned — expired edit debounce timestamps removed on each new edit

_users cache — capped at 5,000 entries with gentle FIFO eviction; updated in real-time via updateUser events
_chats cache — capped at 500 entries; new chats from updateNewChat evict oldest when full; individual chat inserts use _cacheChat
_pinnedMessageIds cache — capped at 200 entries; pin/unpin events update cache; unpin removes entry

Exit freeze on Neovim close — server now exits immediately on SIGTERM (without awaiting TDLib close), Neovim doesn't wait for the job
First-exit lag — TDLib's first-time database finalization no longer blocks Neovim's shutdown
Remote session termination — updateAuthorizationState (closed/logging-out) clears all caches and notifies Lua UI
Stale typing indicators — typing_users entries for the previous chat are cleaned up on open_chat switch

SIGTERM exits immediately — closes HTTP/WS servers and calls process.exit(0) without tgClient.shutdown(); SIGINT (Ctrl+C) still does graceful shutdown
getGroups() always fetches fresh — reverted to getChats(true) to avoid stale chat list when chats are removed
