My July has gotten a lot more crowded than I expected, and it’s become clear that Boxer 1.4 will not be ready in time for the impending release of OS X 10.8 Mountain Lion. So, I released Boxer 1.3.2 as a stopgap: this has a few minor bugfixes and is Developer-ID signed to be trusted by Mountain Lion's new Gatekeeper system.
I'll be very busy over the next couple of months with Real Life commitments, so Boxer’s development will be quiet for a wee while and Boxer 1.4 may not arrive until later this year. Fear not though, exciting things are on the way!
