What is piecepackr?

A board game graphics package runs one of the most disciplined deprecation cycles in R.

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

What is qtl2convert?

A conversion utility in pure maintenance mode, tracking R-devel breakage release by release

qtl2convert is the format-shim of the R/qtl2 ecosystem: it moves genotype probabilities and genetic maps between DOQTL, R/qtl and R/qtl2 representations. The last three releases contain no new conversion functions at all — 0.32 fixed a C string comparison flagged by CRAN, 0.34 restored attribute-clearing that R-devel 4.7 changed underneath the package, and 0.36 adjusted parallel core defaults plus a test tweak. The functional surface has been stable since 0.26 added cross2_ril_to_genril().

A board game graphics package runs one of the most disciplined deprecation cycles in R.

◆ Current state

piecepackr renders game pieces — piecepack, chess, dominoes and related systems — as 2D grid graphics, 3D meshes, animations, and print-and-play PDFs. Its interface is mature enough that most releases are about managing change rather than adding capability: features get deprecated with a named replacement, live through a release or two, then get removed on schedule. The current release completes the cycle opened a year earlier, retiring the new_device and style arguments in favour of open_device and the composable font, border, background_color and edge_color set.

◆ Where it's heading

Two things dominate the log. The first is that deprecation discipline, unusually explicit for a package this size — every removal names its successor, and deprecations announced in one release are removed in a predictable later one. The second is defensive dependency management: version bumps pinned around bugs introduced upstream in rayrender and rayvertex, a warning class for known-buggy cairo versions with an option to suppress it, and suggested packages required for metadata embedding with clear messages when they are absent. Functionality still arrives — vectorised 3D object export that finally handles composite pieces, new crosshair grobs, a reworked colour palette — but it arrives inside that maintenance rhythm rather than driving it.

◆ Prediction

The features deprecated in this release — the preview_layout component and the 4x6 print-and-play size — are on the established path toward removal in a future version, with the documented ppdf-based replacement already in place.

◆ Current state

qtl2convert is the format-shim of the R/qtl2 ecosystem: it moves genotype probabilities and genetic maps between DOQTL, R/qtl and R/qtl2 representations. The last three releases contain no new conversion functions at all — 0.32 fixed a C string comparison flagged by CRAN, 0.34 restored attribute-clearing that R-devel 4.7 changed underneath the package, and 0.36 adjusted parallel core defaults plus a test tweak. The functional surface has been stable since 0.26 added cross2_ril_to_genril().

◆ Where it's heading

This is a package whose release cadence is driven by its dependencies, not its roadmap. Two of the last three releases exist purely because upstream R or CRAN's check suite moved; the maintainer responds within weeks and ships. The cores=0 change in 0.36 is the only user-visible behavior shift in over a year, and it landed simultaneously in sibling package qtl2fst — this is a maintainer-wide convention change, not a qtl2convert decision.

◆ Prediction

Expect the next release to be triggered by another R-devel or CRAN check change rather than a feature request, following the same pattern as 0.32 and 0.34.
