After a number of slipped release dates (and the most extensive testing of any release), Media Browser 2.3.0 went RTM on the 14th - this is a significant release which addresses a number of performance issues, most notably issues centred around updating the library which caused quite a pain for users with large media collections. The library update process has now been moved to a service (no more high CPU utilization for the ehexthost process!).
Some highlights for this release:
Fixes for broken podcast handling
A number of fixes to the default theme
Prep work for Custom Intros prior to movies playing
Better Media Info Icons and fixes
Startup is significantly faster, no more artificial lag when playing HD content
