• Fixed an issue that prevented from ports to be directly activated in INIT state.

• Fixed an issue that prevented activating virtual ports on first time master sweep when running with --once.

• Fixed a memory leak when parsing QoS policy file with errors.

• Fixed an issue that prevented the incrementation of of outstanding AN2AN/VS/CC MADs when no response was expected.

• Fixed a crash that occurred during a race between the LFT record get query and routing configuration.

• Fixed a non-generic notices statistics counters in the dump file.

• Fixed the postponing isolation and reporting process of the noisy ports.

• Fixed an issue related to the selecting of the held back/isolated switches as roots for multicast trees.

• Fixed an issue that caused the unresponsive links to to remain in Active state.

• Fixed an issue that affected the writing of invalid AN2AN links to SMDB dump file.

• Fixed the IPoIB traffic loss after changing the subnet prefix and loading the MC groups from SADB upon SM restart.
