LIMB 2.3.1(candle) Release

Hi folks, we're glad to announce the release of LIMB 2.3.1(candle) version!

This is primarily a bugfix, mess cleanup and speed optimization release.

As for optimization, we tried to cache tree calls maximally, thus reducing total SQL overhead (in some cases it may result in about 30% overall perfomance speedup). This lead to total refactoring of tree subsystem and we hope there are enough tests to make sure everything works fine.

However some more thorough testing is still required since we had to add some dirty hacks into access policy subsystem due to tree changes(we hope to refactor access policy stuff in 2.4).

See CHANGELOG ( http://svn.berlios.de/viewcvs/limb/php4/tags/2.3.1/CHANGELOG?rev=1313&view=markup ) for further details.
