Release Notes

Released on 2026-05-14.

Breaking changes

These are narrow cleanup breaks in behavior that was either temporary or never worked correctly. Most users should not need to change anything.

• Generated hook scripts no longer preserve -q, -v, or --no-progress passed to prek install. This only affects users who expected those global flags to be baked into installed hooks. (#1966)
• language_version no longer accepts direct executable paths. Use language_version: system for a system toolchain, or use a supported version request instead. This path form did not work reliably before, so existing working configs should be unaffected. (#1831)

Enhancements

• Expand tilde in --config, --cd, --log-file and --git-dir (#2063)
• Prevent auto-update cooldown downgrades (#2055)
• Use managed npm cache for node hooks (#2075)

Bug fixes

• Fix npm config env overrides for node hooks (#2074)

Documentation

• Add cookbook page for enabling Git 2.54 config-based global hooks (#2061)
