Brian #1: pip 25.1 has dependency groups, pylock.toml, plus more
- post What's new in pip 25.1 - Dependency groups!
- Richard Si
- Discovered this through Hugo van Kemenade
Dependency groups, PEP 735, supported
# pyproject.toml
[dependency-groups]
test = ["pytest", "pytest-xdist"]
lint = ["mypy", "isort"]
# Dependency Groups can include other groups! ✨
dev = [ {include-group = "test"}, {include-group = "lint"} ]
Package installation progress bar
- Resumable downloads
- Experimental lockfile generation, PEP 751, with pip lock
- pip index versions is stable, no longer experimental
- use this to get a list of available versions
- ex: python3 -m pip index versions pytest-check
- combine with --json to get a nice script readable output
Michael #2: aiohttp goes free threaded
- Thanks to months of consistent contributions by Lysandros Nikolaou, all of the mandatory dependencies of #aiohttp now ship free-threaded variants of #wheels!
- This unlocks the same in aiohttp!
Brian #3: uv 0.6.15 supports pylock.toml
- Discovered through Brett Cannon
- So far, these projects support pylock.toml
- With uv
- To export a uv.lock to the pylock.toml format,
- run: uv export -o pylock.toml
- To generate a pylock.toml file from a set of requirements,
- run: uv pip compile -o pylock.toml -r requirements.in
- To install from a pylock.toml file,
- run: uv pip sync pylock.toml or uv pip install -r pylock.toml
Michael #4: Whenever
- via Pat Decker
- Typed and DST-safe datetimes for Python, available in Rust or pure Python.
- Whenever helps you write correct and type checked datetime code.
- It's also way faster than other third-party libraries—and usually the standard library as well.
