Little Snitch 3.6.3
Objective Development has released Little Snitch 3.6.2, fixing a memory leak in Little Snitch Configuration and an incompatibility with the Little Snitch Installer in some older OS X versions. The update to the network monitoring and diagnostic utility also fixed an issue that could cause the Connection Alert to become unresponsive, improved the Installer to reliably terminate Little Snitch Configuration during installation, and fixed a rare issue that could cause a kernel panic. Shortly after this release, Objective Development released Little Snitch 3.6.3 to fix a bug causing the Little Snitch Uninstaller to crash. ($34.95 new, free update, 21.3 MB, release notes, 10.8+)
I just checked for updates in my copy of version 3.6.2 and it said I was up to date!
