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 WPML?

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

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.

WPML made machine translation the default, and its point releases keep chasing WordPress and page builders.

◆ Current state

The shipping 4.9 line is compatibility work: WordPress 7.1 support with a security hardening pass in the newest release, PHP 8.5 compatibility and a smoother site-migration flow before that, and WordPress 7.0's iframe-based block editor before that. The 5.0 beta running in parallel is the larger move — a redesigned interface, a simplified translation engine, and automatic translation switched on by default for new sites.

◆ Where it's heading

Two clocks again. The maintenance clock is dictated entirely by other people's releases: WordPress majors, PHP versions, Divi 5, Elementor. Enough of this feed is compatibility that it reads as the real cost of being a translation layer inside someone else's ecosystem. The product clock points one direction, toward automation — cost and time estimates before sending content, one-click recovery for stuck jobs, automatic detection of custom Elementor widgets, and now automatic translation as the starting state rather than an option. The 4.9.7 security hardening is worth noting alongside a beta in flight: the stable line still gets real attention.

◆ Prediction

Expect the 5.0 line to move from beta to production with the automatic-first defaults intact, followed by continued compatibility maintenance as WordPress core and major builders evolve.
