We're pleased to announce the release of PennMUSH 1.7.7p14. Both a patch and the tarball are available in the usual place (see Download link above)
The most significant change in this version is the introduction of the chunk-based memory manager, and its most noticeable effect is that infrequently-used attribute texts are now swapped to disk, reducing overall memory use significantly (about 40% around here) with little performance penalty. However, swapping does currently prevent forking dumps from working (they'll be forced to nonforking) so if you've got a lot of memory and you're really attached to forking dumps, be sure you read the comment in mush.cnf about how to set the memory cache large enough that swapping never happens.
Other major changes in this release include Ancestor objects. Full list in the CHANGES file.
