The deadline is no longer theoretical: browsers, Git HTTPS backends and API clients that still depend on SHA-1-era TLS algorithms can now lose connectivity to GitHub.com.
The corrected rollout matters for supply-chain configuration: teams can still remove PATs for qualifying GitHub Packages, but GitHub changed the precedence model after some npm update jobs were mistakenly routed through GitHub Packages.
Teams with pinned, custom-image or auto-update-disabled GitHub Actions runners can now see registration or job execution fail before the September 25 cutoff. The migration is not just a one-time jump to v2.329.0: already-registered runners must also stay within 30 days of the latest runner release.
This is a compiler-correctness fix rather than a routine patch. Code built with Rust 1.98.0 can be wrong even when the source is valid, so teams that adopted that stable release should update and rebuild affected artifacts.
The CLI itself is not being deprecated. The risk is narrower and operational: stale Linux repository keyrings can stop package installs or updates from verifying after the old signing key expires.
Node.js shipped v22.23.2, v24.18.1 and v26.5.1 to close a set of runtime vulnerabilities including an HTTP/2 use-after-free and a Permission Model path-matching bug that can over-grant filesystem access.
