The protist reference database keeps widening past the rRNA gene it was built on.
A side-by-side editorial comparison of Jackett and PINstimation — release velocity, themes, recent moves, and the top alternatives to consider.
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.
A market-microstructure toolkit that keeps adding estimators as the papers land.
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.

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.
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.
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.
Each release tracks the literature: a Bayesian PIN estimator from Griffin et al., an improved VPIN from Ke and Lin, initial-parameter generation realigned to Ersan and Ghachem. The other steady thread is data handling — matrix inputs so the estimators compose with rolling windows, user-specified aggregation frequencies, and now quote leads as well as lags. The three-year gap between 0.1.2 and 0.2.0 makes this a slow, publication-paced package rather than an actively developed one.
On this pattern the next release adds whatever estimator the authors publish next, since two of the three feature releases here implement a specific paper. Nothing in the entries points to a change in the package's structure.
