 - 2022-xx-yy: 2.8.0-beta.1
   - UNMERGED PR #271: Small pkgconfig and cmake detection improvements. Enable unity build.
-  - UNMERGED PR #270: For Windows, basis sets with a star have been renamed to "s" on the filesystem,
+    Testing of solid harmonics runtime switchable from #269.
+  - PR #270: For Windows, basis sets with a star have been renamed to "s" on the filesystem,
     so 6-31g**.g94 -> 6-31gss.g94. In code, the basis can be accessed through "6-31g**" (longstanding)
     or "6-31gss" (new) for all operating systems.

+  - PR #270: Adapt build system and header imports so that library and Python bindings can build on
     Windows (at least with clang-cl compiler atop MSVC). Note that a Linux- or Mac-generated export
     builds on Windows; one cannot generate an export on Windows. Note also that only a static library
     build, not a shared one, works on Windows (see #237).
