Gecode 6.3.0 and 6.4.0 released

[Mikael Zayenz Lagerkvist]

Dear all,

We would like to announce the release of Gecode 6.3.0 and Gecode 6.4.0.

These releases mark a new start for Gecode. Active development has moved to the main branch, replacing the previous master and develop split. From now on, Gecode releases will be source-only.

Gecode 6.3.0 records the changes accumulated on the release/6.3.0 branch since Gecode 6.2.0. Much of this work concerns the MiniZinc and FlatZinc interfaces, together with fixes in the integer, support, and search modules.

The main change in Gecode 6.4.0 is the build and installation flow. CMake is now the intended build system. Gecode now installs a CMake package that downstream projects can use with `find_package(Gecode CONFIG)`.

The traditional configure-and-make build remains supported for this release. We plan to discontinue it in a future release.

Gecode 6.4.0 also adds new propagation functionality and contains a broad set of correctness and stability fixes. The old contrib modules are no longer included.

The full changelog and source packages are available from

Cheers,
The Gecode team
