rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild
A side-by-side editorial comparison of saperlipopette and ToolJet — release velocity, themes, recent moves, and the top alternatives to consider.
saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
ToolJet's LTS line is where the features land now, while beta collects single-line fixes.
ToolJet runs two release trains in parallel and this window makes the split obvious: the 3.20.x LTS branch carries the actual feature work — dynamic number formatting on Currency Input, dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, camera flip on mobile, and AI build notifications — while the 3.21.x beta branch contributes two entries totaling three cherry-picked fixes. Security and connectivity plumbing also sits on LTS: global certificates across data source connections, automated RDS SSL setup, and a container-scan CVE sweep.

The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.

The component-level work is converging on one complaint — layout that does not adapt — with dynamic height now applied to six widget types across three releases. The AI thread is quieter here than in the recent beta history but has not stopped: AI build notifications ship in 3.20.212-LTS, and 3.20.209 lists a batch of AI feature fixes, which suggests the AI builder is now in the maintenance phase that follows a launch rather than the expansion phase.
Expect dynamic height to keep spreading to the remaining widgets, since it has arrived in three consecutive LTS releases. The beta branch looks likely to stay a staging area for LTS cherry-picks until the next minor opens.
