Aider v0.80.0 Release Notes — What's New

OpenRouter OAuth integration:
- Offer to OAuth against OpenRouter if no model and keys are provided.
- Select OpenRouter default model based on free/paid tier status if OPENROUTER_API_KEY is set and no model is specified.
Prioritize gemini/gemini-2.5-pro-exp-03-25 if GEMINI_API_KEY is set, and vertex_ai/gemini-2.5-pro-exp-03-25 if VERTEXAI_PROJECT is set, when no model is specified.
Validate user-configured color settings on startup and warn/disable invalid ones.
Warn at startup if --stream and --cache-prompts are used together, as cost estimates may be inaccurate.
Boost repomap ranking for files whose path components match identifiers mentioned in the chat.
Change web scraping timeout from an error to a warning, allowing scraping to continue with potentially incomplete content.
