The Mozilla Organization has posted Mozilla 1.3a, the latest release of the popular open-source Web browser. Version 1.3a contains new Mail and Newsgroup features and fixes, as well as a quicksearch for bookmarks. A complete list of improvements can be found here. Mozilla 1.3a is available for Mac OS X. “We’re transitioning the Mac Classic (OS 8.x and 9.x) build to Mozilla Port status. This means that mozilla.org won’t be making official Classic builds beginning with 1.3alpha,” states the release notes. “For 1.3alpha (but probably not later releases) users of OS 9 with carbonlib can use the OS X (CFM) build.”
