tidyr
tidyr replaced separate() with a family that says what it does.
A side-by-side editorial comparison of ggplot2 and PySCF — release velocity, themes, recent moves, and the top alternatives to consider.
ggplot2 swapped its object system out from under a decade of downstream code
The 4.0.0 release replaced ggplot2's S3 internals with S7 and made every geom's defaults settable from the theme, both breaking changes. The three releases since have been hotfixes cleaning up the fallout - regressions in geom_area(), position_stack() and the scale and guide systems - plus rlang interoperability repairs. The one genuinely new feature in that window is a quantile.type argument on boxplots.
Quantum chemistry package adding whole method families every release.
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.

This is the tail of a long-telegraphed migration: 3.5.2 existed largely to give downstream packages the is_*() predicates and accessor functions they would need before 4.0 landed. With theme(geom) and from_theme(), styling is consolidating into the theme rather than being repeated per layer, which is the direction the extension ecosystem now has to follow.
Expect further 4.0.x patches as S7-related regressions surface in extension packages, and more of the per-geom default surface to migrate into element_geom(). The entries give no indication of a 4.1 feature line yet.

Two arcs are visible. The methods arc is pushing toward periodic (PBC) parity with molecular calculations — PBC GW, PBC RPA, SOC-ECP for PBC DFT, QM/MM for periodic systems all landed in this window. The infrastructure arc is about getting PySCF to run where it previously did not: Windows, GPUs, alternative tensor-contraction backends.
The PBC catch-up should continue, since each release closes another gap between molecular and periodic implementations of the same method; the entries do not indicate which gap is next.
