Per Dan's post on the LOR forum:

The firmware is stable with no know issues. If you would like to try it out before general release please do so and let us know at if you have any issues.


Previously, an individual sequence could only last for up to ten minutes. It can now last up to 44 hours.
Previously, only certain manufacturer's SD cards were supported. A much larger variety is now supported (list to be compiled - although it will more likely be a list of unsupported cards rather than a list of supported cards)
Support for SD cards with the FAT32 file system was added.
Support for SDHC (high capacity) SD cards was added.
When a sequence started playing, in some rare cases the music and the lights would start off significantly out of sync with each other. (fixed)
