What is Gatekeeper?

Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.

3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.

What is NetBird?

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

Gatekeeper grew a package manager for policies — and a benchmark to prove they are not too slow.

◆ Current state

3.22.0-rc.0 in February introduced two CLI subcommands that change how policies are handled rather than what they express: gator policy, a brew-inspired tool for discovering, installing, upgrading and uninstalling policies from the gatekeeper-library, and gator bench, which benchmarks Rego and CEL engines with latency percentiles, throughput, memory profiling and baseline comparison for CI regression detection. The same release enabled sync-vap-enforcement-scope by default and gave both CEL and Rego access to namespace context during admission and audit. Since then, 3.23.0-rc.1 added status resource routing for remote cluster mode, and 3.24.0-beta.0 made generated ValidatingAdmissionPolicy output deterministic to stop a reconcile loop.

◆ Where it's heading

The centre of gravity is moving from the admission controller to the tooling around it. Policies are becoming artefacts you install from a library at a version, benchmark against a baseline in CI, and test before they reach a cluster — which is the lifecycle application code already has and policy generally has not. Underneath, the ValidatingAdmissionPolicy path keeps maturing as Gatekeeper hands more enforcement to the Kubernetes-native mechanism it now generates.

◆ Prediction

Remote cluster mode gained status routing but the entries describe only that piece, so how far multi-cluster enforcement extends is unclear from these notes. The releases in this window are all beta and release candidates, so a 3.24.0 stable is the near-term milestone.

5.0

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

◆ Current state

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

◆ Where it's heading

After v0.81 focused on device trust through certificate posture checks, v0.82 is about the management plane's storage and on hardening the built-in SSH server. Deprecating Rosenpass signals a change in how NetBird approaches post-quantum key exchange, though the entries do not name the replacement.

◆ Prediction

Expect v0.82.0 final with the MySQL removal intact, and a later release introducing the Rosenpass replacement.
