Changes in version 2.21.2 (2026-06-17)
+ The bundled MC-UPGMA clustering suite (external C++/Perl/GNU-make tool) has
  been replaced by a portable in-package C++ reimplementation. netboost no
  longer requires GNU make, Bash, Perl or Gzip and now builds on Windows in
  addition to unix/macOS. Sparse-clustering output is byte-identical to
  previous versions for the supported single-round regime (edge count up to the
  former 1e7 heap size); very large inputs that previously triggered the
  external tool's multi-round mode may yield identically-structured trees with
  differently-numbered cluster IDs.
+ SIMD (AVX) acceleration of the boosting step is now selected at runtime via
  the executing CPU's capabilities instead of being baked in at build time. The
  same binary runs correctly across heterogeneous CPU clusters (AVX and
  non-AVX nodes) and on non-x86 architectures; CPU-feature autodetection
  (autoconf) was removed.
+ Removed the exported helper mcupgma_exec(), which only operated on the
  now-removed external clustering binaries.

Changes in version 2.21.1 (2026-06-17)
+ Improved computational efficiency.

Changes in version 2.19.3 (2026-02-12)
+ Consensus network calling.

Changes in version 2.19.2 (2026-02-11)
+ Speed up of filter calculation.

Changes in version 1.99.4 (2021-04-15)
+ Removal of MCUPGMA-dependencies for smaller networks.

Changes in version 1.99.0 (2021-03-08)
+ Fully rank based extension (netboost(...,robust_PCs=TRUE,filter_method="spearman",method="spearman")).
+ Full support of the non-parametric version.

Changes in version 1.1.1 (2019-05-06)
+ Introduction of Pearson-, Spearman- and Kendall-based filtering.

Changes in version 1.0.0 (2019-04-02)
+ Final submission changes for Bioconductor.
