The messy-date parser rewrote its core in Rust and came out 300x faster.
A side-by-side editorial comparison of beautier and fellingdater — release velocity, themes, recent moves, and the top alternatives to consider.
A BEAST2 XML generator shipping releases CRAN can't accept because the CRAN team is on holiday.
beautier turns R code into BEAST2 phylogenetics XML input files. The three most recent releases landed over four days in August 2025 and are all explicitly marked pre-CRAN, held back because the CRAN team was on summer holiday. The substance sits in 2.6.13, which added tip-date file handling; the two after it are lint and bug fixes.
Went from estimating felling dates to doing the crossdating that produces them.
fellingdater estimates when a tree was felled from sapwood measurements, the core inference in dendrochronological dating of timber. Version 1.0.0 passed rOpenSci review with that scope, and the 2024 releases were mostly about the accompanying JOSS paper and user-supplied sapwood datasets. Version 1.2.0 changed the package's remit substantially, adding an entire trs_* family for tree-ring series handling: crossdating with multiple statistical measures, the Hollstein and Baillie-Pilcher t-value transformations, parallel variation percentages, synthetic series generation, and dated-series plotting.

Development is fine-grained and test-driven — releases are small, numbered in tight sequence, and reported against a fixed NEW FEATURES / MINOR IMPROVEMENTS / BUG FIXES / DEPRECATED template with 100% code coverage tracked as a line item. The recent work concentrates on validating user-supplied input files rather than expanding BEAST2 model coverage, which suggests the model surface is considered largely done and the remaining friction is in what users feed it.
The pre-CRAN backlog should be squashed into a single CRAN submission once the release window reopens; further work is most likely more input-file validation in the same check_/read_ family.

The package has expanded backwards along the workflow. It began at the last step — given dated series, estimate the felling date — and 1.2.0 added the step before it, establishing those dates by crossdating in the first place. Version 1.2.1 is early polish on that new surface: axis control, non-syntactic column names, encoding safety in read_fh(). The direction is a single package covering the chain from raw ring widths to a felling-date estimate.
Expect the trs_* family to keep accumulating polish and additional crossdating statistics, since it is barely a year old and 1.2.1 was already fixing its plotting and top_n behaviour. Whether the two halves of the package get unified into one workflow interface is the open question the entries do not answer.
