LifeType Team have just released a new maintenance release of the 1.1 branch :
LifeType 1.1.2. Issues addressed in LifeType 1.1.2 but the development team decided that there was not need to hold this release back any longer, and maked the 1.1.2 release available for public. Issues fixed in this release are the post preview feature, which now works with any character encoding, improved memory usage when listing the contents of resource albums, and several improvements to TinyMCE and the 'inservideo' plugin in order to make it easier to embed Flash videos in posts.
You can download LifeType 1.1.2 or download the upgrade from 1.1.1 to 1.1.2. LifeType is one of the very popular and powerful muti-blogs and multi-users platform, built with speed in mind. Performance have been improved since the development cycle of the software and I think today it's becoming much more stable and powerful blogging software.
