v9.4 (2022/08)

Platforms

• Add Debian-10 support (#3209)
• Add Ubuntu 22.04 LTS support (#3276)
  • note: won't have .Net 3.1 support (see: dotnet/core#7038 (comment))
• Remove Ubuntu 21.10 support

Misc

• Split archive by languages and add CMake config to the C++ one (#3200)

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)
