Skipper adds RFC 9421 HTTP Message Signatures and delivers 21% RouteGroup load time improvement
A side-by-side editorial comparison of Contour and Jackett — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Jackett in pure tracker-maintenance mode, daily domain and category updates only
Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.
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.
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.

The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.
The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
