compositional.mle
An MLE package rebuilt around composable solvers, then renamed to match.
A side-by-side editorial comparison of kwb.geosalz and libr — release velocity, themes, recent moves, and the top alternatives to consider.
A research-project workflow package where the interesting work is in the plumbing.
kwb.geosalz documents the data workflows for GeoSalz, a groundwater salinisation project run by Kompetenzzentrum Wasser Berlin, packaging retrieval, checking and plotting steps as reproducible R code. The current release replaces an SFTP dependency with curl and reports listing files on the SFTP server running 50 to 100 times faster. Earlier releases added data-availability workflows against Berlin's open water portal and functions for well-field abstraction figures.
The SAS datastep clone for R just got roughly nineteen times faster.
libr gives R users SAS-style data libraries and a datastep() construct, sitting alongside logr, reporter and procs in the r-sassy suite for analysts moving clinical workflows off SAS. Most of its release history is narrow bug-fixing in the libname() readers, particularly the sas7bdat engine. The exception dominates the window: a single 2026 release that rewrote datastep() performance and cut the installed package to a quarter of its former size.

Releases track the project's own data-collection reality rather than a software roadmap: new data source appears, a workflow is added; a transfer library becomes a liability, it is swapped out. The measurement-chain pipeline is the recurring subject, appearing in plotting fixes at 0.7.1 and the transport rewrite at 0.7.2. Cadence is roughly annual and the changelog is written for project members, which makes external readability secondary by design.
Expect the next release to follow the measurement-chain data as it accumulates, most likely more plotting or availability-checking work rather than new infrastructure.

The exception dominates the window: a single 2026 release that rewrote datastep() performance and cut the installed package to a quarter of its former size.
Two threads run through these entries — steady correctness work on SAS file import, and a much less frequent but far more consequential push on making datastep() viable at real data volumes. The recent fix to empty-variable typing suggests the sas7bdat reader is still where edge cases surface. Having addressed both speed and package size in one release, the obvious remaining pressure is correctness and coverage of SAS semantics rather than throughput.
Expect the next releases to continue narrowing sas7bdat import edge cases, with any further datastep() work aimed at supporting more SAS syntax rather than at speed.
