This release fixes major abusable bugs. Player visible changes include usable group, fleet, wing and army conditionals.
Deities are urged to use this release for new games. Upgrading mid-game is not supported and expected to result in total disaster.
There are no client binaries for this release, as changes are limited to configuration. Client binaries did not change since 4.3.0.
Our pthreads code has known problems with shutdown. In particular, the shutdown command may fail to terminate the server process. So far, this has been observed only with LinuxThreads under Linux 2.4 and earlier. Note that configure prefers LWP over pthreads when both are available, as they are on most platforms.
Solaris /bin/sh has a broken test builtin. Try passing SHELL=/usr/xpg4/bin/sh PATH=/usr/xpg4/bin:$PATH to make.
Attention, client writers: xdump changed, please peruse the change log.
