Important Notes

Graphics performance, as measured by the graphics section of the Phoronix test suite (http://www.phoronix-test-suite.com/), is still being improved. Also, running the 3DMark®Mobile benchmark test (http://www.rightware.com/en/Benchmarking+Software) will cause a crash.
SW Video codec support in this release is for Ogg format only. Customers needing hardware acceleration for video decoding of other formats will need to license codecs from a 3rd party, such as Fluendo (https://fluendo.com/en/).
An open source SW flash decoder is included in this build. An evaluation version of a HW accelerated flash decoder is available from Intel at: https://registrationcenter.intel.com/RegCenter/ComForm.aspx?ProductID=1618.
Be sure to select the “Flash_10.2_CDT” download for the MeeGo RPM, and follow the instructions in the release notes to install it.
