Added
- Support for PHP 8.0
Changed
- Optimisation when packing a large number of items
- Improved efficiency in packing and weight distribution
- The ItemList passed to VolumePacker's constructor is now cloned before usage, leaving the passed-in object unaffected. Previously this was used as a working dataset. The new behaviour aligns with the existing behaviour of Packer
Fixed
- Fixed issue where internal sort consistency wasn't always correct
- Fixed situation where internal WorkingVolume could be passed into a constraint callback, rather than the calling application's own Box
- Fixed issue where the list of previously packed items passed into a constraint callback was not correct
Removed
- Making the test suite compatible with PHP 8.0 has necessitated the removal of support for PHP 5.4 - 7.0 (see note below)
v1 of BoxPacker is in maintenance mode only, all users are encouraged to update to v3. This release has been made primarily to certify PHP 8 compatibility, unless an egregious bug is discovered (e.g. a physically impossible packing) this will be the last v1 release that includes any changes to core packing logic. (Any) further releases will be limited to compatibility with future PHP versions.
