The folks at IM+ have just pinged us to let us know that version 4.0 of their application is now available. They’re calling it a major upgrade, and judging from this changelog alone I wouldn’t be inclined to disagree. Here’s the full list of changes:
Completely new user interface with new features
Various screen DPIs support for equal precise app look on all devices
Push messages support for longer battery life
Custom statuses and message templates
Skype topics
LED notification and customizable sounds for incoming messages
Chinese and South Korean localizations
Major bugfixes and performance improvements
All that sounds pretty major to me. You can get a free ad-supported version of IM+ or pay for an ad-less version for $4.95 in the Android market.
