natcpp 0.3.1 (2026-07-20)

• fix package loading on CRAN's Debian clang r-devel check by conditionally linking libatomic when the C++ atomic compare/exchange runtime helper is required.
• add src/Makevars.win, since configure is not run on Windows, and a cleanup script to remove the src/Makevars generated by configure. The generated src/Makevars is no longer shipped in the package sources.

natcpp 0.3.0 (2026-07-08)

• add weighted Jaccard similarity functions for sparse data
  • c_weighted_jaccard_sparse() returns a sparse similarity (or distance) matrix
  • c_weighted_jaccard_dense() returns a dense matrix or a dist-layout vector
  • both run in parallel via RcppThread, with an optional progress bar (RcppProgress)
  • triangle= switches between symmetric upper-triangle output and a full matrix
  • distance= returns 1 - similarity
• portable src/Makevars using $(SHLIB_OPENMP_CXXFLAGS) in place of a GNU make $(shell ...) callout to RcppThread::LdFlags()
