FastAPI shipped a memory optimization that simplifies how dependencies are processed, backed by months of community analysis and benchmarking.

Version 0.140.0 landed with a core refactor that reduces memory usage in the dependency system [1], the result of deep work by the team to address inefficiencies identified across multiple discussions and previous attempts [2]. The release also updated docs to use uv projects by default and added new Library Skills documentation [1], moving the framework closer to modern Python tooling standards. Separately, CI now includes memory benchmarks [4] to catch future regressions automatically. Docs cleanup work fixed 404 links and redirects [3], small but necessary housekeeping as the ecosystem stabilizes.
