Jackett vs Skipper: at a glance
What is Jackett?
Daily tags chasing tracker domain moves, login changes and freeleech detection
Jackett continues to ship a tag most mornings, each one a short auto-generated commit list of indexer definition edits. The newest adds a cookie login variant for HD-Space and captcha-aware login for funfile; the day before was a sweep of domain bumps and download-volume-factor detection corrections across torrenttip, magnetcat, 52bt, torrenteros, tocashare and seedcore. No release in this window touches the application itself.
What is Skipper?
Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

Daily tags chasing tracker domain moves, login changes and freeleech detection
◆ Current state
Jackett continues to ship a tag most mornings, each one a short auto-generated commit list of indexer definition edits. The newest adds a cookie login variant for HD-Space and captcha-aware login for funfile; the day before was a sweep of domain bumps and download-volume-factor detection corrections across torrenttip, magnetcat, 52bt, torrenteros, tocashare and seedcore. No release in this window touches the application itself.
◆ Where it's heading
This is maintenance as a product, and the cadence is the feature. Trackers rotate domains, add captchas, switch to cookie auth or vary their freeleech percentages, and Jackett absorbs each change within a day — Scenetime was added and dropped within days, 720pier removed and then restored by revert. The recurring shift from form login to cookie and captcha handling across sites is the one visible pattern: the definitions are steadily taking on more anti-bot handling.
◆ Prediction
Expect the same daily cadence of definition edits, with more cookie and captcha login variants as trackers tighten access. The entries show no application-level work planned or in progress.

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
◆ Current state
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.
◆ Where it's heading
Two threads run through the recent tags. The data path keeps getting real work - leastRequests balancing, then h2c end to end in v0.27.57, now the memory cost of zone-aware routing being paid back. The auth filters, by contrast, are only being maintained: token introspection, grant auth, and now the OIDC Referer handling are fixes rather than new capability, and several are follow-ups to each other rather than independent bugs.
◆ Prediction
Zone-aware routing looks like the source of the recent memory attention, so expect further tuning around route storage and the hash computation done on every pull, which the release's second benchmark already isolates. The OIDC cookie change is the second link in an auth chain that started with the grant-auth fix, and is likely to draw another follow-up.
