# Aider v0.77.0: 130 new linter languages via tree-sitter-language-pack

> Aider switches to tree-sitter-language-pack, adding linter support for 130 more languages and repo-map support for 20 more. Adds `/think-tokens` and `/reasoning-effort` commands for runtime control of reasoning budget, and turns on `--auto-accept-architect` by default so architect-format changes apply without confirmation.

## What changed


- Adopted tree-sitter-language-pack: 130 new languages with linter support, 20 new with repo-map support
- New `/think-tokens` command — sets thinking token budget, accepts human-readable values (8k, 10.5k, 0.5M); shows current setting when called bare
- New `/reasoning-effort` command to control model reasoning level; shows current setting when called bare
- `--thinking-tokens` now accepts string values in human-readable formats
- Thinking token budget and reasoning effort shown in model information
- New `--auto-accept-architect` flag (default: true) — architect-format changes are accepted without confirmation
- Added `cohere_chat/command-a-03-2025` and `gemini/gemma-3-27b-it`
- Bare `/drop` now preserves original read-only files passed via `args.read`
- Autocomplete now requires 3 characters
- Fixes: deprecated `--shortcut` switches overriding an explicit command-line model; JSONDecodeError on model cache load; GitCommandError on git user config; file watcher `ignore_permission_denied` option
