# 08 — Current release register (https://jackin.tailrocks.com/research/context/tools/08-current-release-register/) ## Summary [#summary] The release register fixes every comparison to a 2026-08-12 snapshot so superseded versions and stale benchmark claims cannot silently enter current verdicts. Authoritative dossier snapshot: **2026-08-12 UTC**. “Latest” means the newest stable GitHub release visible at the cutoff, or newest tag when a project does not publish release objects. Adoption and activity fields come from GitHub's repository API. Stars are not an outcome metric. ## Question and scope [#question-and-scope] Which exact stable releases and maintenance signals define the dossier’s current comparison set? ## Method [#method] The register queries release or tag metadata at the stated UTC cutoff, records the newest stable artifact and maintenance signals, and excludes stars from outcome judgments. ## Findings [#findings] ### Core tools [#core-tools] | Tool | Current release | Published | Current adoption | Last repository push at cutoff | License today | | ------------------------------------------------------- | --------------------------------------------------------------------------: | ---------: | --------------------------------------: | -----------------------------: | --------------------------------------------------------------------------------------------------------------------------------------------- | | [Caveman](https://github.com/JuliusBrussee/caveman) | [v2.0.0](https://github.com/JuliusBrussee/caveman/releases/tag/v2.0.0) | 2026-08-11 | 97,512★ / 240 subscribers / 5,622 forks | 2026-08-11 | MIT interfaces;

they do not append a release history. A changed stable version requires re-reading the release, current architecture, license, install/telemetry behavior, and evidence before carrying any verdict forward. ## Implications for jackin❯ [#implications-for-jackin] For jackin❯, the current release register evidence determines whether the mechanism is suitable for reuse, comparison, or rejection. ## Limitations and unknowns [#limitations-and-unknowns] ### Freshness defects found in current upstream docs [#freshness-defects-found-in-current-upstream-docs] * RTK's current README verification example names an older version than v0.45.0. * RTK's current privacy and disclaimer documents disagree about telemetry default. * Headroom's current `SECURITY.md` labels an older release as latest. * lean-ctx v3.9.18 release notes contain a self-comparison changelog link. * Paritok publishes current tags but no GitHub release objects. These defects do not change the release metadata above. They lower confidence in unaudited prose and justify linking exact release artifacts. ## Sources [#sources] Evidence and repository references are cited inline beside the claims they support. ## Related work [#related-work] * [Token-optimization tools dossier](/research/context/tools/) * [Token-optimization techniques](/research/context/techniques/) * [Context engine](/research/context/engine/)
