i have build 2 new version of SliceOS today
Slice-Slice.arm-6.0-devel-20150820143804-r21151-gc1509d7 which is only updated to Kodi 15 but based on the Bloody build
Slice-Slice.arm-6.0-devel-20150820145132-r21259-g5402e1c is based on Kodi 15.1 plus bring it inline with the latest master of OpenELEC, so even more Bloody than the Bloody build
i have tested that they both install just by extracting the files from the target directory and copying to the update folder via samba
USE AT YOUR OWN RISK!!
