-------------------------------------------------------------------
Thu May 11 00:30:26 UTC 2023 - Stefan Brüns <stefan.bruens@rwth-aachen.de>

- Update to version 9.6:
  * Dependencies
    + SCIP v801 -> v803 (note: now uses an OSI compatible license)
    + abseil 20220623.1 -> 20230105.0
    + Protobuf v21.5 -> v21.12
    + SWIG 4.1.1
  * PDLP
    + Add python wrapper.
  * CP-SAT
    + Performance improvements.
  * GLOP
    + Tweak presolve.
  * ModelBuilder
    + Python: Improve numpy support.
  * Bazel
    + Add pybind11 support.
    + Add java wrapper support.
  * Routing
    + Few improvements (local search)
  * Known Issues:
    + CP-SAT: Ignoring pseudo_costs subsolver returns Invalid
      parameters. (#3706)
- Update to version 9.5:
  * CP-SAT
    + Presolve improvements: max(array), Boolean constraints,
      linear constraints.
    + Interleaved search should be deterministic in parallel.
    + Linear cuts: cleanup square and int_prod cuts; rewrite
      cut pipeline.
    + Fingerprint input model and solution (visible in the log).
    + Scheduling improvements
    + The usual bunch of bugfixes (crash during presolve, crash in
      cuts, infeasible solutions, model infeasible in LNS).
  * GLOP
    + Speedup by rewriting the linear algebra, as well as the
      pivot selection rule
  * Linear Solver
    + add knapsack_interface.cc.
    + Move model_builder API under the linear_solver directory
      (headers and samples).
    + Add support for Gurobi 10.
  * Routing
    + Liberate few parser for various routing challenge.
- Drop obsolete patches:
  * do_not_call_pdlp_solve_test.patch
  * 0003-Reuse-common-add_cxx_example-function-for-Sat-Runner.patch
- Update patches:
  * 0001-Only-add-relevant-directories-to-sample-RUNPATHs.patch
  * 0002-Only-add-relevant-directories-to-flatzinc-library-ex.patch
  * 0003-Only-add-relevant-directories-to-sat_solver-RUNPATHs.patch
- Use PIP_NO_INDEX instead of
  0001-Do-not-try-to-download-ortools-wheel.patch

Fri Nov 25 12:12:32 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de>

- Fix build with SWIG 4.1

-------------------------------------------------------------------
Sat Sep 17 16:21:13 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de>

- Update to version 9.4:
  * Graph
    + Split ortools.graph.pywrapgraph into:
      - ortools.graph.python.linear_sum_assignment
      - ortools.graph.python.max_flow
      - ortools.graph.python.min_cost_flow
      This allows using numpy to speed up the setup of the problems.
  * CP-SAT
    + Some improvement on:
      - scheduling (propagation, cuts, lower bounds)
      - MaxSAT (presolve, core based heuristics)
      - MIP performance (presolve, cuts)
- Drop upstream patches:
  * fix_re2_string_view.patch
  * 0001-Build-Python-modules-as-CMake-MODULEs.patch
  * fix_malformed_Cpp.patch
  * 0001-Set-SWIGWORDSIZE-dependent-on-architecture-bitness.patch
- Add patches:
  * do_not_call_pdlp_solve_test.patch
  * 0003-Reuse-common-add_cxx_example-function-for-Sat-Runner.patch

-------------------------------------------------------------------
Fri Jul 15 12:31:32 UTC 2022 - Stefan Brüns <stefan.bruens@rwth-aachen.de>

- Fix failing builds due to stricter RUNPATH checks, add
  * 0001-Only-add-relevant-directories-to-sample-RUNPATHs.patch
  * 0002-Only-add-relevant-directories-to-flatzinc-library-ex.patch
