v1.3

• Fix problem where available space calculation inadvertently missed off a dimension

v1.2

• Expose remaining space information on a packed box
• Fix bug that preferred less-optimal solutions in some cases

v1.1

• Supports HHVM
• Tweaked algorithm to allow limited lookahead when dealing with identical objects to better optimise placement
• Misc internal refactoring and optimisations

v1.0.1

Bugfix release, fixes issue with vertical depth calculation where last item in a box could be judged not to fit even though it would

v1.0

• Generated solutions now have a second pass where multiple boxes are involved, in order to redistribute weight more evenly

v0.4

• Minor calculation speedups

v0.3

• Now packs items side by side, not just on top of each other
• Generated solutions should now be reasonably optimal

v0.2

• Supports solutions using multiple boxes
• API should be stable now - no plans to change it
• Generated solutions may not be optimal, but should be correct

v0.1

• Basic prototype
• Experimental code to get a feel for how calculations can best be implemented
• Only works if all items fit into a single box (so not production ready at all)
