charliermarsh · x · 2026-10-21

uv 0.13.4 updates its bundled CA certificates in response to the eMudhra incident. According to the author, this is a huge deal and not unique to uv: bundled CAs in certifi, webpki-root-certs and similar libraries mean much of open source is affected. Anything that bundles CA certs should be upgraded.
