# Aider 0.85.0: Gemini 2.5 and o3-pro support, alias repointing, gitignore-file flag

> Adds Gemini 2.5 Pro/Flash with thinking-token support and Responses-API models such as o1-pro and o3-pro, and repoints the `flash` and `gemini` aliases to the 2.5 models — so existing configs using those aliases will silently target a different model. Also adds several CLI flags (`--add-gitignore-files`, `--commit-language`, PostHog analytics options), MATLAB and Clojure repo-map support, and turns Co-authored-by commit attribution on by default.
