FastAPI 0.136.0 landed on April 16, 2026 with incremental fixes and dependency bumps on top of the 0.135 line. The release inherits the Python 3.10 minimum introduced in 0.130.0, so apps still on 3.9 will not pick it up on auto-update. No API surface break is noted in the changelog — this is a maintenance train in a popular version. Adoption context: FastAPI's share of Python web frameworks has climbed from 29% to 38% over the past year, riding async patterns and Rust-backed components. Teams upgrading should double-check async middleware and OpenAPI generation paths, where most regressions surface.
