We just published patch release for version 3.5 (binary version 3.5.133) that fixes few critical issues in server and database manager. Full change log:

• Fixed server deadlock when unreachable node is deleted
• Fixed SNMPv3 performance issue
• Fixed issues:
          NX-1966 (MySQL / MariaDB database access performance issues)

Only server component is affected, there is no need to update agents or UI.

Best regards,
Victor
