v9.12

Platforms

  • This will be the last release to support Python3.8.
  • Add Python 3.13 support.
  • Add muslinux wheel package.
  • This will be the last release to support Java 1.8

Builds

  • dependencies (protobuf, abseil, re2, highs) are now seperated shared libraries
  • Windows libraries are now dll

Dependencies

C++

  • Protobuf 29.3
  • CoinUtils: 2.11.12
  • Osi: 0.108.11
  • Clp: 1.17.10
  • Cgl: 0.60.9
  • Cbc: 2.10.12
  • HiGHS: 1.9.0

Graph

  • Old graph classes (EbertGraph, StarGraph, ForwardEbertGraph, ForwardStarGraph) have been removed. Use ReverseArcListGraph<> and ListGraph<> instead. Those are conceptually similar, but typically perform better. APIs are mostly compatible.

CP-SAT

  • Improve the no_overlap_2d layer (propagation, presolve, cuts)
  • Add RandomHalfBranching search heuristics
  • Improve Cumulative propagation and cuts
  • Rewrote the hint transformation during presolve. Feasible and complete hints should now be preserved after presolve
  • Rewrite and optimize the linear expression part of the python layer
  • Improve shared tree workers, implement job affinity with workers
  • Add scheduling samples
  • Support 1-var affine expressions in the Automaton constraint
  • Support 1-var affine expressions in the Element constraint
  • Speed up LNS
  • Tens of fixes for bugs found by fuzzer

Linear Solver

  • Add WriteModelToMpsFile to MPSolver in Java, Python and .NET
