• Added Advanced Encryption Standard (AES) support for SNMP v3. This includes 128 bit encryption in compliance with RFC 3826, as well as Cisco-specific extensions to support AES 192 bit and 256 bit encryption.

• Fixed an issue where privacy-related bytes would be incorrectly transmitted if the driver was configured with SNMP v3 "Authentication but no Privacy" security.

• Fixed an issue where the driver improperly assigned the "contextEngineID? and thus did not allow communications with certain target devices that enforce the proper use of contextEngineIDs.

• Made a change wherein the Username is now required in the SNMP v3 Security property page and validation displays the last valid name if the user tries to delete it.

• Passphrase characters are now obfuscated in the same manner for all passphrase fields. Content is obfuscated but length is not.

• Passphrase fields are no longer cleared when a change to the security level is applied in the SNMP v3 Security property page.

• Fixed an issue where tags would have bad quality if the data type length was in long form.

• Added (EncExtAsc) as an encoding identifier (appended to the OID in the Address field) so extended ASCII characters will be human readable instead of represented in Hex.

Fixed an issue with Set (Write) operations where the driver would not always encode integer values in the smallest possible number of octets. For certain managed devices, this could cause the Set operation to fail.

• Added the "Port Offset" device property to the Network Analyst sheet and wizard pages.

• Changed the "Points in Moving Average" key combination shortcut on the Network Analyst sheet and wizard pages from Alt-A to Alt-M.

• Increased the maximum number of channels from 100 to 256.

• Traps can now be disabled if channel serialization is disabled (when Channel Virtual Network set to "None").
• The driver no longer automatically generates tags for unrelated device configuration changes like Port, Protocol, and so on.

• Migrate scan floor functionality from SNMP custom device properties to standard server device properties.
• Expanded the "Deactivate tags on NoSuchObject/Instance errors" option to include SNMPv1 "NoSuchName" errors in CSnmpFrame. This device property applies to all polling that uses Get requests, including polls for Network Analyst Tags. Previously, Network Analyst Tags were not affected by this setting.
• Fixed an issue that could make the Runtime unresponsive when loading certain projects.
• Added Inform support for SNMPv2c/v3 Traps/Notifications.
• Added Communication Serialization (virtual network support) to the SNMP Driver. To meet the serialization requirements, the SNMP Driver now serializes tag processing and device discovery.
  Note: Trap reception will be disabled when the SNMP channel is a member of a virtual network.
• Removed the dependency between the number of varbinds that a Defined Trap could receive and the "Number of Fields" value used for Event Tags.
• Fixed an issue when reading values from OIDs of SNMP data type UInteger32.

• Fixed an issue where changing from v2c to v1, the "GetBulk" check box selection was not being persisted.
• Fixed a host name resolution issue where the driver was no longer receiving SNMP Traps from a device after the device's IP address changed.
• Added the ability to invalidate rather than deactivate tags that receive "NoSuchInstance" and "NoSuchObject" errors from a device agent.
• Added support for Authentication and Encryption of SNMP messages (SNMPv3 security).

• Enhanced MIB parsing capabilities by providing the ability to multi-select MIBs for import, and also made the parser more tolerant of minor MIB warnings (syntax or format) that should not prevent import.
• The user is now prompted when a MIB dependency exists in both the repository and the Import target directory. If the user confirms overwriting, the repository file will be deleted and the target file will be added to the repository.
• Importing a file that is contained in the repository now causes the existing file to be deleted, and the new file added. Before, the old file was not deleted and the two files coexisted.
• Formatting change for user imported MIBs from "UserImported-<file name>" to "UserImported-<module name>_<file name>".
• Fixed an issue in the MIB Import tab of Device Properties wherein selecting "Customize" following removal of a module would re-add the previously removed module.
• Added the SNMP GetBulk command in order to read multiple OIDs from individual tables more efficiently. This is a user-selectable device property and is only used for SNMP version 2c.
• Fixed an issue wherein traps with snmpTrapOid varbinds with trailing ".0s" were not handled correctly.
• Fixed an issue with processing trap events from devices that pad the timestamp of the trap event packet with zeros.

• The default SNMP MIB template selection was changed from "Switch" to "Other".
• Fixed bug where driver was using an invalid transaction id format resulting in unnecessary transaction retries.
• Added support for auto device discovery.

• Fixed Trap event handler to receive Traps correctly after IP changes when the device is in use (has active items).
• Disabled Scan Floor and Lock controls on Device Communications property page if the device is in use (has active items).

• Added auto tag generation support for a variation of a "trap OID" containing an enterprise specific type.

• Added multi-threaded communications support.
• Improved MIB import capabilities.
