The release contains many great new features and fixes but it is an
_alpha_ release; Expect bugs.
Mozilla 1.3a marks the transition for Mac Classic builds (those created
explicitly for Mac OS 8 and 9) to "port" status. This means that
mozilla.org won't be making official builds for Mac Classic starting
with the 1.3 cycle. We think that we have a maintainer for the Mac
Classic port and if so there will be builds available for future
releases, like the dozen or so other ports that will depend on a
committed maintainer.
You can find builds at the releases page.
