I just released a new version (1.5.4) which can be found in the Downloads page.

Here is a list of changes:

– Removed OneManga

– Added Manga-Haven, Manga Fox and Manga Stream

– Fixed problem opening CBR archives on a 64 bit machine.

– Images with uppercase extensions inside a CBR or CBZ should now work. Let me know if they don’t.

– MGA and WMGA thumbnails should now work on 64-bit versions of Windows Vista and 7.
