Aider v0.83.0: Gemini 2.5 & OpenRouter Support

TL;DR

• Gemini 2.5 Pro preview and Qwen 3 235B model support added
• OpenRouter now auto-fetches model parameters and pricing directly
• New --attribute-co-authored-by flag for commit attribution control
• Python 3.9 support dropped; Aider wrote 55% of this release

New

• Gemini 2.5 Pro preview support — Added gemini-2.5-pro-preview-05-06 with updated aliases pointing to latest preview versions.
• Qwen 3 235B models — Full support for Qwen's latest large language model.
• OCaml repo-map support — Aider now understands OCaml and OCaml interface files for better code context.
• Commit attribution flags — --attribute-co-authored-by, --attribute-author, and --attribute-committer for fine-grained control over commit messages.
• OpenRouter auto-configuration — Model parameters and pricing now fetched directly from OpenRouter's website; added support for thinking_tokens and reasoning_effort.
• Shell completions — New --shell-completions argument generates bash/zsh completion scripts.
• Playwright control — --disable-playwright flag prevents installation prompts; aider scrape now uses Playwright when available.
• Spinner animations — Knight Rider-style spinner now shows during LLM streaming and non-streaming responses with better console handling.
• Token tracking — Total tokens sent/received now included in benchmark statistics.
• /ask mode improvements — LLM now elides unchanging code in responses for cleaner output.

Fixed

• Windows linter execution — Fixed argument quoting issues on Windows using oslex.
• Read-only file handling — Fixed issue where read-only status wasn't preserved after commands like /drop.
• Gemini model settings — Corrected gemini-2.5-pro-exp-03-25 to reflect lack of thinking_budget support.
• System prompt formatting — Model-specific prefixes now placed on new line before main prompt.

Breaking Changes

• Python 3.9 support dropped — Aider now requires Python 3.10 or later.
• Gemini model aliases updated — gemini and gemini-2.5-pro now point to 05-06 preview versions; marked as overeager by default.
