Version 1.1.1

This release fixes a compilation error with newer versions of GCC.

Version 1.1.0

This release fixes a compilation error when installing the gecoder-with-gecode gem using GCC 4.4+ .

Version 1.0.0

This release represents a commitment to the current syntax.

Version 0.9.1

This release changes the preferred way of defining a model to including Gecode::Mixin (a mixin) rather than inheriting from Gecode::Model. The backend has also been updated to fix some rare bugs.

Version 0.9.0

This release adds a generous amount of sugar designed to cut down on often repeated code. It also adds the ability to freely combine constraints without needing temporary variables.

Version 0.8.3

This release adds regular expression constraints, the last channel constraint and various minor convenience improvements. It also fixes a rather serious bug that occurs when using the latest patchlevels of Ruby 1.8.6.

Version 0.8.2

This release adds search statistics along with some new arithmetic constraints and channel constraints between boolean and integer variables.

Version 0.8.1

This release adds tuple constraints along with a couple of minor features. It also fixes a bug introduced in the previous version.

Version 0.8.0

This release makes the jump from using Gecode 1.3.1 to using Gecode 2.1.1 . The following changes have been made to the interface as a result of the jump.

Version 0.7.1

This release adds boolean linear constraints.

Version 0.7.0

This release adds the set selection and operation constraints.

Version 0.6.1

This release fixes various bugs introduced in 0.6.0 and changes the way that int variable domains are specified (breaking backward-compatibility).

Version 0.6.0

This release adds most of the remaining set constraints. It also makes backward-compatibility breaking changes to the way that properties of variables are accessed.

Version 0.5.0

This release adds set variables and some of their constraints, along with the last of the boolean constraints.

Version 0.4.0

This release adds most of the integer variable constraints supported by Gecode.

Version 0.3.0

This release fleshes out the existing constraints with things such as reification and adds boolean variables and their basic constraints.

Version 0.2.0

This is the first release of Gecode/R, a Ruby interface to Gecode.
