# Uno 2.7.3

* Updated the bundled Uno C++ solver to upstream release 2.7.3. The R-packaging
  patch set was rebased onto v2.7.3; the C API is backward-compatible (the
  binding is unchanged). One internal fix: Uno 2.7.3 relocated
  `Options::dump_default_options()`, so its console output is re-routed through
  the R-output mechanism (`UNO_COUT`) to keep the compiled library free of raw
  `std::cout` for the CRAN compiled-code check.

* Added `inst/COPYRIGHTS` documenting the copyright holders and licenses of the
  bundled third-party libraries: the Uno C++ solver and HiGHS, including the
  components HiGHS itself bundles (AMD, METIS, pdqsort, zstr, rcm, filereaderlp,
  Catch2, and CLI11). All are permissive and MIT-compatible
  (MIT / BSD-3-Clause / Apache-2.0 / zlib / Boost Software License 1.0); none is
  copyleft. A `Copyright: file inst/COPYRIGHTS` field and a `cph` entry for the
  HiGHS development team record this in the package metadata. Because the file
  lives under `inst/`, the attribution survives installation. MUMPS (reached at
  run time through the GPL-licensed `rmumps` package) and BQPD are not bundled.
