- Changed streams from UCHAR to ULONG as Dmitry wanted - Got rid of some redundant flags to indicate BLR level - Misc changes (for example, converted to test for DBB_read_only in Database to a function) - BLR v6 is left commented (waiting for a better solution to appear, if any exists) - This change is not going to raise the engine limits until a solution is found to express more than 255 streams in BLR.
