- The SaveBlob method now checks for duplicates. - Moves handling of pending blobs to MasterIndex. -> also cleans up pending index entries when they are saved in the index -> when using SaveBlob no need to care about index any longer - Always check for full index and save it when storing packs. -> removes the need of an index uploader -> also removes the verbose "uploaded intermediate index" messages - The Flush method now also saves the index - Fix race condition when checking and saving full/non-finalized indexes
