Risks

Compatibility Risk with Updated Cache Action [Medium]

Updating actions/cache to v4 may introduce breaking changes not compatible with the current workflow configuration. Reviewing the release notes of the new version and testing in a non-production environment could mitigate this risk.

Cache Key Handling Changes [Low]

The new version of actions/cache could alter the way hashFiles or cache keys are interpreted, leading to cache inefficiencies. Since the current configuration is working with v3, any new hashing mechanism or key parsing in v4 could pose a risk to the current caching strategy.

Cache Path Compatibility [Low]

If actions/cache@v4 changes how paths are processed, this might disrupt caching operations for existing workflows. Verification of path handling in the new version is necessary to ensure no disruption occurs.
