Pip 25.2: Resumable Downloads By Default

This week pip 25.2 has been released, it’s a small release but the biggest change is resumable downloads, introduced in 25.1, have been enabled by default.

Resumable downloads will retry the download at the point a connection was disconnected within the same install or download command (though not across multiple commands). This has been a long standing feature request for users which have slow and/or unreliable internet, especially now some packages are multi-GB in size.

Richard, one of the pip maintainers, has again done an excellent write up: https://ichard26.github.io/blog/2025/07/whats-new-in-pip-25.2/

The full changelog is here: https://github.com/pypa/pip/blob/main/NEWS.rst#252-2025-07-30

One thing not obvious from either is the upgrade to resolvelib 1.2.0 improves most pathological resolutions significantly, speeding up the time for pip to find a valid resolution for the requirements. There is more work to do here, I will continue to try and find improvements in my spare time.
