Pip supports locking, .pth files deprecated **[Bite Code](https://daily.dev/sources/bitecode)** · 4 min read · 3 upvotes · 2 comments ## Summary A roundup of Python ecosystem news for May 2026. The headline item is pip 26.1 gaining experimental lock file support via the new pylock.toml standard (PEP 751), allowing commands like `pip lock .` and `pip install -r pylock.toml`. PEP 829 introduces .start files as a safer, more structured replacement for .pth files, using entry-point syntax instead of arbitrary exec() calls. Other highlights include Python 3.15.0 beta 2 (feature-complete with lazy imports and unpacking in comprehensions), Mypy 2.0 and 2.1 releases with parallel type checking, new uv/ruff/ty tutorials from PyDevTools, Django's GSoC 2026 plans, and a significantly faster Python VS Code extension update. ## Full article daily.dev links to this article rather than hosting it.
