Full Summary
Gecode, a constraint programming library, has launched two new versions: 6.3.0 and 6.4.0, after a seven-year gap since the last release. Version 6.3.0 consolidates changes from the previous version, while 6.4.0 marks a shift to a main development branch using CMake as the primary build system.
This version simplifies the installation process and enhances MiniZinc integration, including support for new constraints and improved error handling. Notably, Gecode 6.4.0 introduces an experimental black-box propagator interface, allowing custom value propagation without modifying the core solver.
