Jackett vs PowerTOST: 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 PowerTOST?
A bioequivalence sample-size workhorse whose news is which regulator it now covers
PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.

Jackett

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.
PowerTOST
0.0INFRA · APIS
A bioequivalence sample-size workhorse whose news is which regulator it now covers
◆ Current state
PowerTOST computes power and sample size for bioequivalence and its changelog reads as a record of regulatory divergence more than statistical development. Version 1.5-3 added the Gulf Co-operation Council as a regulator setting; 1.5-4 and 1.5-6 stripped 'FDA' out of the narrow-therapeutic-index function names once China's CDE began requiring the same evaluation. The most recent release, 1.5-7, is a single fix to how nvec() splits a total sample size across sequences.
◆ Where it's heading
The package is in long maintenance with a widening regulatory surface: the statistical methods are settled, and releases arrive when an agency publishes a framework that can be expressed as a settings variant of an existing method. Function naming has been deliberately decoupled from any single agency, with the deprecated FDA-suffixed aliases carried for years before removal. Cadence has slowed to roughly one release every eighteen months.
◆ Prediction
The next release is most likely another regulator setting or a small fix; on the deprecation notice already given, the power.NTIDFDA()-style aliases are the obvious removal candidate.
