I've noticed that we are missing metastore schema and upgrade files for version 0.11. I know that the metastore structure has not been changed between 0.10 and 0.11, thus they are not strictly necessary.
However in the same situation in the past (for example when going 0.2 -> 0.3 or 0.8 -> 0.9) we've always copied the metastore files from previous release. I believe that this is more user friendly approach as user can simply use the metastore schema file for his version without thinking which file to use.
I know that 0.11 is out and that we are currently working on 0.12, but I believe that we should add those files retrospectively anyway.
