paleobuddy
paleobuddy can now simulate trait-dependent diversification, not just birth-death.
A side-by-side editorial comparison of bittermelon and treespace — release velocity, themes, recent moves, and the top alternatives to consider.
bittermelon is growing from binary bitmaps toward greyscale and color glyphs
The package manipulates bitmap fonts and bitmaps in R, and the recent direction is widening what a glyph can be. v2.3.1 adds greyscale font support by reading the experimental yaff levels property into pixmap glyphs with alpha derived from the level fraction, and makes writing a multi-colored glyph an error rather than silently clamping it. Earlier releases built out the same surface: bm_extract(), an interactive pixel picker, data frame coercion, and format support for other packages' bitmap types.
treespace ships once every year or two, and only when CRAN or a user forces it.
treespace explores and compares sets of phylogenetic and transmission trees, including the tree-distance measures used in outbreak reconstruction. Its release history is entirely reactive: five updates across five years, each triggered by a CRAN policy change, an upstream package removal, or a bug someone reported. The most recent is an Rd cross-reference format patch plus a maintainer email change.

Two things are converging. The representation is moving beyond one-bit glyphs — pixmaps, color, and now greyscale levels with transparency — while the API gets stricter about the boundary between them, refusing to quietly downcast a color glyph on write. Separately, the package has been shedding weight: the embedded monobit copy was removed once it outgrew CRAN size limits, pushing format breadth onto a user-installed dependency.
Expect further greyscale and color work now that levels parsing exists — most likely writing that format rather than only reading it, since the write path is where the current release chose to draw a hard error instead.

The package is stable and lightly staffed rather than abandoned — bugs that affect correctness do get fixed, and CRAN deadlines are met. But the 2023 update is the telling one: rather than vendor or replace adephylo when it faced removal, the maintainers disabled two tree-vector methods and marked the loss as hopefully temporary. Two years on, nothing in the feed indicates they came back.
The next entry will most likely be another CRAN-compliance patch, on the pattern of four of the last five releases. Whether the Abouheif and sumDD methods ever return is not something these entries give any signal on.
