Two new releases. 1.8.0p12 is just bugfixes, and some small improvements in networking and logging.
1.8.1p7 includes many new features. Important changes: The FIXED flag's restriction on home no longer happens in the hardcode -- you must add it to restrict.cnf! Also, the LIGHT flag now overrides DARK consistently; as a consequence, DARK wizards appear in LIGHT rooms.
Some of the new stuff includes @lock/take (who may get something from a container, replaces @lock/enter for this purpose), improved @chan/recall and crecall(), speak(), ulambda(), unique(), nextdbref(), namelist().
There are also a slew of new minor improvements and tweaks.
