## [Version 17.2.1][v17.2.1]
Patch release which includes a fix for a bug in the OPK session state machine
logic. Previously the state machine code would only allow OEMCrypto_MoveEntry()
to be called when a usage entry had been loaded. This misses a few use cases
from the CDM where OEMCrypto_MoveEntry() could be called immediately after
opening a session or waiting for a license.
This bug could result in situations where users are unable to download offline
licenses. If the usage table is completely filled (~300 entries by default in
OPK), then this bug may occur when the CDM tries to move old entries to make
room for new licenses. Similarly, if the usage table has gaps where previous
entries were deleted, then this bug may occur when the CDM tries to defragment
the usage table by moving newer usage entries into those gaps.
