Greenbone's scanner daemon is growing a web-application scanning class beside its network roots.
gvmd releases every week or two, and the changelog splits cleanly in three: a sustained build-out of web application scanning, a rewrite of how reports are modeled and exported, and a long tail of memory-management fixes in the C core. Recent versions added web application scanner preferences, scanner verification, and a Web Application VT subtype with a database migration. The report work moved from ad-hoc XML toward a structured report model addressable through new GMP commands.
Three supported branches, patched in lockstep within the same minute.
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.

Greenbone is widening what gvmd can orchestrate. Network and container scanning were the existing surface; web application scanning is being brought to parity, with its own VT class, preferences, validation, and verification path. In parallel the GMP protocol is gaining first-class report retrieval commands, which makes report data consumable by tooling rather than only renderable. The bug-fix stream is dominated by frees and cleanup in long-lived report paths, the signature of a codebase under memory pressure at scale.
Web Application VTs now have a subtype, a migration, and scanner verification, but the audit and scan report commands were added separately; expect the report model work to fold web application results into the same structured retrieval path rather than leaving a parallel one.

The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.
This is a proxy whose release cadence is governed by its data plane rather than its own feature work. Envoy security releases set the schedule, and Contour's job is to bump, verify compatibility and ship across every supported branch simultaneously. The changes that do originate in Contour are operational sharp edges found in production: an HTTPProxy CRD schema wrongly marking a status error field as required, which broke load balancer status updates, and shutdown-manager being CPU-throttled at a 50m limit.
The next release will almost certainly be another simultaneous three-branch batch triggered by an Envoy security bump, since both batches in this window followed exactly that pattern.
