released:

CR00005227 Module: SWI, RSTP, SWMX,
SWCX, SW56
A heavy processor load could lead to queuing RSTP BPDUs, which in turn
could lead to even more processor load, resulting in more queued BPDUs.
This issue has been resolved by improving the efficiency in the interaction
between RSTP TCN BPDUs and the hardware tables.
This issue has been resolved. (PCR number: 40672)
Level: 1
CR00006609 Module: LB Level: 1
When failover occurred between a redundant pair of Load Balancing

timed out the stale entry. This issue has been resolved. (No PCR number.)
