Name change may hint at imminent release, changes currently unknown
Apple on Thursday released an updated beta of OS X Mavericks, the forthcoming major system upgrade for OS X users. The new version, the ninth, drops the "Developer Preview" part of the name and simply refers to it as "OS X Mavericks," suggesting that pre-release work on it is drawing to a close. Mavericks (otherwise known as OS X 10.9) is widely expected to be released sometime later this month, though Apple hasn't set a formal date as of yet.
The new build, 13A598, is just a few digits up from the previous build, 13A584 -- also hinting that work on the beta is winding down. There are no listed major changes, but later investigation by testers usually turns up some minor tweaking.
The public release of Mavericks will feature Maps for OS X, iBooks for OS X, Finder Tabs and other efficiency features such as Compressed Memory and App Nap, which should enhance power savings in the company's MacBook line in addition to savings coming from the updated Intel Haswell chip. To that end, conventional wisdom has it that Apple will hold back updated MacBook Pro models (and possibly other Mac models) until Mavericks is publicly released.
