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 Verdaccio?

Verdaccio's 7.0 line is subtraction — forks dropped, toolchain swapped, tags mostly empty

The next-7 prerelease line is short and almost entirely maintenance. Its one substantive release adopted @verdaccio/server and deleted the local api, web, and storage forks, leaving a thin Storage wrapper behind only to keep callback-based storage plugins working. Everything since has been dependency retargeting, a lint and format toolchain swap, and a tag whose body reads 'chore: trigger release'.

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.

Verdaccio's 7.0 line is subtraction — forks dropped, toolchain swapped, tags mostly empty

◆ Current state

The next-7 prerelease line is short and almost entirely maintenance. Its one substantive release adopted @verdaccio/server and deleted the local api, web, and storage forks, leaving a thin Storage wrapper behind only to keep callback-based storage plugins working. Everything since has been dependency retargeting, a lint and format toolchain swap, and a tag whose body reads 'chore: trigger release'.

◆ Where it's heading

This is consolidation ahead of a major: the project is collapsing code it had been carrying in-tree back onto shared packages and standardising tooling around oxlint and oxfmt. The remaining compatibility shim is the visible unfinished business — it exists purely for legacy plugins, and it is the last thing standing between this line and a clean server dependency.

◆ Prediction

Removing the legacy storage wrapper is the decision this line is heading toward, and it breaks callback-based storage plugins when it lands, so expect it to arrive with the 7.0.0 final rather than in another next tag. Until then the prerelease stream will keep producing tags with no user-visible content.
