A new stable firmware version (100413_1555) has been released for all Dune player models - both the current models (Dune BD Prime 3.0, Dune HD Base 3.0), and all previous models (Dune HD Base 2.0, Dune HD Base, Dune HD Center, Dune BD Prime, Dune HD Mini, Dune HD Ultra).
This version has very few differences (mostly bugfixes) from the previously released 100307_2100_beta version. This firmware version is considered to be the most stable and bug free version in comparison with any previously released firmware versions, and thus is recommended to everyone. New big features and further improvements will be included into future beta versions.
