RSA vs ToolJet

RSA vs ToolJet: at a glance
What is RSA?
Four years quiet, then two releases ninety seconds apart, both about drawing better plots
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.
What is ToolJet?
Observability lands on OpenTelemetry semconv in the LTS train
ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.

◆ Current state
RSA implements response surface analysis for congruence questions in psychology, built on lavaan. After four and a half years of silence the maintainer pushed 0.10.6 and 0.10.8 within ninety seconds of each other on 2 October 2025, so the feed's version sequence is a backfill of accumulated work rather than two separate release events. Both are plotting releases: user-defined lines and points on the surface, stilts for selected data points, and separate control of point fill and border colour.
◆ Where it's heading
The statistical core has been stable since 0.10.0 in 2020, which added control variables, pooled centering and a corrected AICc. Everything since is either plot customisation or a reaction to a dependency — lavaan model comparison, rgl deprecations, tkrplot on Apple Silicon, the ggplot2 fill aesthetic. This is a mature method implementation in maintenance, where the visible work is making its surface plots publishable.
◆ Prediction
Further releases are most likely dependency reactions, with rgl and ggplot2 the two that have repeatedly forced changes, and plot customisation arriving in batches whenever the maintainer returns to the package.

Observability lands on OpenTelemetry semconv in the LTS train
◆ Current state
ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.
◆ Where it's heading
Most releases are small and corrective, with feature work collecting into occasional larger LTS drops. The recurring themes are component sizing, which appears in nearly every release, and enterprise-operations work — global data source certificates, automated RDS SSL setup, CVE patching, and now standards-based observability. It reads as a platform hardening for self-hosted enterprise deployments.
◆ Prediction
Expect the dynamic-height and sizing pass to continue across the remaining widgets, and the beta line's AI datasource integrations to graduate into the LTS train. Standardizing on OTel semconv suggests exported traces and metrics for customer-run dashboards next.
