Beta Beat: Simple sync with Changes

This one is ostensibly for developers, but if you ever rock a revision control system or get excited about a little late-night diff-and-merge for whatever reason, your life may have just gotten easier. Changes is an app designed to simplify project synchronization and differencing for groups or individuals working locally or remotely. It provides a GUI and an impressive list of features for an initial release, including MacFuse support, Subversion and other SCM integration, a TextMate bundle and a command line utility.

Yes, it bears a resemblance to FileMerge, but Changes offers features and options well beyond Apple's aging utility. Because it uses existing systems (chdiff) and provides a plugin SDK, it's both easy to implement and extensible. The command line utility and F-Script support provide additional options for incorporating Changes into your existing workflow. I appreciated the familiar interface and was impressed by how simple it was to integrate Changes into my existing TextMate/Subversion workflow with a few keystrokes.

Changes, which is a Leopard-only release, is currently in beta and is available for immediate download. As of today, the download requires registering for a beta key but the developer has let us know that an upcoming build will switch to a simple time-locked beta. If you dig the software you can get a pre-release discount on a full license, receiving $10 off the $39.95 release price, but the offer is only good until the end of the beta period. And, less importantly, I made it through the whole post without a Bowie reference. Phew.

Update: The new build mentioned above has been released and no longer requires registering for a beta key. An email address is still required for download, but it's less hassle now.
