What is BayLum?

Bayesian luminescence dating that finally replaced its folder-structure input format.

BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.

What is Retool?

Retool is fencing in its app-building agent — plan mode above, row-level data policies below.

Releases arrive several times a week and split cleanly. One line extends the app-building agent: standing building context, multiple threads per branch, and now a plan mode that shows intended changes before they land. The other tightens administration: PostgreSQL access policies in public beta, BYOK token accounting, an admin onboarding hub, plus self-hosted release and migration notices.

0.0

Bayesian luminescence dating that finally replaced its folder-structure input format.

◆ Current state

BayLum runs Bayesian age models for luminescence and combined OSL/C-14 dating on top of JAGS. The 2024 release rebuilt the front end: a single create_DataFile() replaces the separate single-grain and multi-grain generators, reads BIN/BINX and XSYG directly, and takes a YAML config in place of the old prescribed folder layout. Since then the work has been CRAN compliance and documentation.

◆ Where it's heading

Two long-running threads have converged: making JAGS runs survivable (parallel methods, halved MCMC memory, injectable custom models) and making the inputs survivable (YAML config, consistency checks, auto-detected sample names). With the deprecated generators on their way out, the next phase is removal rather than addition. Release cadence is roughly annual and slowing.

◆ Prediction

The deprecated Generate_DataFile(), Generate_DataFile_MG() and LT_RegenDose() are the obvious next casualties; a release that drops them would be the first breaking change since the YAML rework.

5.0

Retool is fencing in its app-building agent — plan mode above, row-level data policies below.

◆ Current state

Releases arrive several times a week and split cleanly. One line extends the app-building agent: standing building context, multiple threads per branch, and now a plan mode that shows intended changes before they land. The other tightens administration: PostgreSQL access policies in public beta, BYOK token accounting, an admin onboarding hub, plus self-hosted release and migration notices.

◆ Where it's heading

The two lines are the same bet. Retool is making agent-built apps acceptable to organizations that cannot let a generated app decide what data it reads, so every agent capability is paired with a constraint — instructions the agent must follow, a plan the reviewer sees, and access policies enforced at the resource rather than in app code. The self-hosted channel keeps pace, which matters for exactly the buyers those controls target.

◆ Prediction

Expect access policies to extend past PostgreSQL to other resource types as they leave beta, and further review or approval steps around the app-building agent.
