Release 4.4.12

This release fixes a nasty regression introduced in 4.4.11 - inability of a SNMPv3 manager to discover authoritative SNMP engine ID of a peer.

Release 4.4.11

This release introduces a new feature - ability to configure master or localized keys to USM LCD.

Please refer to the change log for complete list of changes.

Release 4.4.10

The major new feature of this release is better VACM implementation. Specifically:

• Added subtree match negation support (vacmViewTreeFamilyType)
• Added subtree family mask support (vacmViewTreeFamilyMask)
• Added prefix content name matching support (vacmAccessContextMatch)
• Added key VACM tables caching for better isAccessAllowed lookup performance

One depreciation update:

• Rebased MIB importing code onto importlib because imp is long
  deprecated

And, of course, a handful of fixes:

• Fixed asyncore main loop to respect non-default timer resolution
• Fixed .setTimerResolution() behaviour of abstract main loop dispatcher
  to update call intervals of the existing periodic dispatcher jobs
• Received MIB objects resolution made more forgiving to errors, added
  optional ignoreErrors parameter to ObjectType.resolveWithMib() to
  control that behaviour.
• Fixed var-bindings initialization to prevent pyasn1 encoder failures
  with newer pyasn1 versions where SequenceOf type looses its default
  initializer.
• Fixed crash on uninitialized component serialization left out in
  SNMP v1 TRAP PDU to SNMPv2/3 TRAP PDU proxy translation routine.

Please refer to the change log for complete list of changes.

Release 4.4.9

This is a bug fix release addressing a couple of bugs:

• Made MIB loader ignoring file and directory access errors
• Added missing SNMP PDU error classes and their handling in Command Responder
• Fixed crash on MIB load failure in case of directory access error
• Fixed socket transparency option (IPV6_TRANSPARENT) to make IPv6 transparent operation functional

Please refer to the change log for complete list of changes.

Release 4.4.8

This release fixes Pythonized MIBs loading bug introduced in 4.4.7.

Please refer to the change log for complete list of changes.

Release 4.4.7

This is a bug fix release addressing a handful of accumulated bugs.

The most important changes are:

• Use compile() before exec'ing MIB modules to attach filename to the stack frames (ultimately shown in traceback/debugger)
• Fixed hlapi/v3arch transport target caching to ensure transport targets are different even if just timeout/retries options differ
• Fixed hlapi LCD configurator to include contextName. Prior to this fix sending SNMPv3 TRAP with non-default contextName would fail.
• Fixed possible duplicate key occurrence in the OrderedDict following a race condition
• Fixed undefined name references in inet_pton/inet_ntop substitute routines for IPv6 in TRANSPORT-ADDRESS-MIB.py

Please refer to the change log for complete list of changes.

PySNMP 4.4.6

This is a bug fix release addressing a handful of accumulated bugs.

The changes are:

• Improved package build and dependency tracking
• Fixed missing LICENSE from the tarball distribution
• Fixed CommandGeneratorLcdConfigurator.unconfigure() to fully clean up internal caches, otherwise repetitive attempts to configure the target would fail.
• Fix to tolerate possible duplicate enumerations in Bits and IntegerSMI types.
• Fix to tolerate non-initialised entries in SNMP community table. Once a bad entry sneaked into the SNMP community table, all the subsequent SNMP v1/v2c operations failed. The fix ignores incomplete SNMP community table entries in the course of building indices.

PySNMP 4.4.5

This is a bug fix release addressing a handful of accumulated bugs.

Most important changes are:

• Added PySnmpError.cause attribute holding parent exception tuple
• Fixed broken InetAddressType rendering caused by a pyasn1 regression
• Fixed possible infinite loop in GETBULK response PDU builder
• Fixed memory leak in the config.delContext() VACM management harness
• Fixed Bits class initialization when enumeration values are given
• Fixed crash caused by incoming SNMPv3 message requesting SNMPv1/v2c
  security model
• Fixed out-of-scope OIDs leaking at the end of SNMP table at hlapi
  nextCmd and bulkCmd calls when lexicographicMode = False

Please refer to the change log for complete list of changes.

PySNMP 4.4.4

This is a minor bug fix release. Most important changes are:

• Fixed short local key expansion at 3DES key localization implementation.

Please refer to the change log for complete list of changes.

PySNMP 4.4.3

This is a minor bug fix release. Most important changes are:

• Added missing SHA2 support for Blumenthal key localization
• Fixed named bits handling at rfc1902.Bits
• Fixed SNMP v1->v2c PDU proxy -- error-status & error-index fields from v1 PDU get copied over to v2c PDU in addition to the exception sentinels being set
