v2.21.1

Compare Source

What's Changed

• Improved performance of the disable-sudo feature.
• Fixed an issue in the Community tier where new endpoints required by the GitHub Actions runner were not being implicitly allowed in block mode.
• Fixed the Harden-Runner post step failing on Linux distributions that do not have a merged /usr filesystem layout (for example Debian 11), where /usr/bin/echo does not exist. This mainly affected self-hosted runners.
• Documentation updates: clarified which features are in the Community (free) vs Enterprise tier.
