Artman21 (http://www.artman21.com/en/jedit_x/) has updated Jedit X, the Cocoa-based text editor for Mac OS X, to version 2.29. The upgrade is compatible with OS X Lion.
Jedit X is an Universal Binary app so runs natively on both PowerPC and Intel Macs. It requires Mac OS X 10.4 or higher. The cost is US$28 for a single-user license, though version 2.21 is a free update for registered users.
