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 massProps?

A mass-properties rollup spends a year on documentation and follows its sibling's API

massProps computes mass, centre of mass and inertia tensors — and their uncertainties — over tree-structured assemblies, the calculation systems engineers run on a spacecraft or vehicle breakdown. It sits on top of rollupTree, the same author's generic recursive-computation engine, and its most recent release exists only to adopt accessor functions that sibling added two weeks earlier.

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.

A mass-properties rollup spends a year on documentation and follows its sibling's API

◆ Current state

massProps computes mass, centre of mass and inertia tensors — and their uncertainties — over tree-structured assemblies, the calculation systems engineers run on a spacecraft or vehicle breakdown. It sits on top of rollupTree, the same author's generic recursive-computation engine, and its most recent release exists only to adopt accessor functions that sibling added two weeks earlier.

◆ Where it's heading

Every release in the window is documentation, benchmarks, or keeping in step with rollupTree. The inertia tensor and radius-of-gyration uncertainty equations have been reformatted and re-explained three separate times, which suggests the hard part of this package is not the computation but making the covariance treatment legible to the engineers meant to trust it. Development effort clearly sits in the engine underneath, not here.

◆ Prediction

The pattern is unambiguous: rollupTree ships an API change and massProps follows within a fortnight. Whatever the engine does next is what appears here next, and on this evidence it will arrive as a one-line release note.
