  - Fix to AsynsockDispatcher.runDispatcher() to make use of optional
    non-default select() timeout value.
  - AbstractTransportDispatcher now allows user application registering
    multiple timer callbacks each with dedicated call period.
  - Asynsock mainloop default idle period reduced to 0.5 sec for better
    timer resolution.
  - Fix to SNMPv1->SNMPv2c error status handling at proxy module. This
    defect may have caused an infinite loop on a multiple var-bind
    SNMPv1 GetNext operation.
  - Fix to contextName processing at config.addV1System -- typo rendered
    passed contextName not committed into LCD.
  - Fix to unknown ContextName exception handling at CommandResponder App.
  - config.addVacmUser() now accepts an optional contextName what makes
    it usable for configuring multiple contextName-bound bases of Managed
    Objects to SnmpEngine.

Mon Feb 16 2009 James Oakley <jfunk@funktronics.ca> - 4.1.10-1
- Update to 4.1.10a
- Internal MIB indexing method __indexMib() unmangled to facilitate
setting up mutex there for sharing MIB stuff between threads.
- Fixed broken IpAddress value handling in SET operation.
- Broken MibBuilder.unloadModules() method now works.
- Use getLabel() SMI object method when building MIB tree (in builder.py)
in addition to direct attribute access for clearer object protocol.
- The MIB building tools updated to match significantly improved
smidump tool (libsmi version > 0.4.5).
- Made libsmi2pysnmp tool optionally building MIB text fields into pysnmp
MIB code (enabled by default) and MibBuilder conditionally loading them
up (disabled by default).
- SnmpEngine and MsgAndPduDispatcher constructors now optionally
take msgAndPduDspr and mibInstrumController class instances
respectively to facilitate these objects sharing within a process.
- Unique integers, for various parts of the system, are now generated
by a nextid.py module. This fixes possible issues with duplicate
request IDs and handlers.
- Built-in MIBs re-generated to include text fields.
- 4.1.9a
- UNSTABLE ALPHA RELEASE.
- At onliner CommandGenerator, close transport on destruction to
prevent socket leak. Implicit async transports registration at
default asyncore's socket map has been disabled to avoid side
effects.
- Fix to rfc2576.v1ToV2c() PDU converter to perform noSuchName error code
translation.
- Fixes to Notification PDU convertion code at rfc2576 in part of
snmpTrapOID handling.
- Fix to nonRepeaters object use as sequence slicer (must be int) at
cmdrsp.CommandResponderApplication
- Make AsynsockDispatcher using its own socket map by default for
threading safety. This will break asyncore apps that rely on pysnmp
sharing the same socket map with them. A solution would be to either
set asyncore map to pysnmp (AsynsockDispatcher.setSocketMap()) or pass
pysnmp map (AsynsockDispatcher.getSocketMap()) to asyncore.
- Fix to response timeout roundup bug at CommandGenerator and
NotificationOriginator code.
- Oneline configuration classes made hashable to prevent memory leaks
when committing them into CommandGenerator/NotificationOriginator
internal repository.
- Security information is now released properly in all MP modules.
This might fix a significant memory leak.
- Typo fix to rfc3411 confirmed class PDU members.
- 4.1.8a
- UNSTABLE ALPHA RELEASE.
- SMI/dispatcher timeout convertion multiplier is actually 100 (1/100 sec)
rather than 1/1000. This fix affects timeouts specified through SMI.
- __repr__() implemented for UdpTransportTarget, CommunityData, UsmUserData
in oneliner module.
- Automatically initialize table index values on table management
operations (SF bug ID #1671989).
- Fix to carrier code: ignore BADFD socket error as it may happen upon
FD closure on n-1 select() event.
- Fix to MibBuilder.setMibPath() to preserve previously loaded modules
intact. Otherwise loadModules() called after setMibPath() might fail
with 'MIB file not found in search path' exception.
- Fix to oneliner classes that now invoke unconfiguration methods on
destruction. This might have caused memory leaks.
- Automatically initialize SNMP-USER-BASED-SM-MIB::UsmUserSecurityName
columnar object instance on creation, as stated in DESCRIPTION (SF
tracker ID #1620392).
- Fix to USM timeframe arithmetics (SF bug #1649032).
- VACM shortcuts merged into universal add/delVacmUser() to let notifications
and requests to co-exist for the same user.
- At oneliners, build LCD tables keys from a hashed mix of input parameters
to make sure these automatic entries won't interfere or exceed constraints
on keys values.
- Made use of notificationType parameter of the sendNotification method
in NotificationGenerator applications. This parameter used to be
ignored in the past. Note, that previously used (and ignored) syntax
has been changed in an incompatible way.
- Allow plain Python values in setCmd() and sendNotification()
methods in CommandGenerator and NotificationGenerator applications
respectively.
- Multi-target oneliner API-based example script added.
- Ignore more socket errors in datagram-type async socket code.
- AES cipher now supported (rfc3826).
- Fix to messed up tagIDs of noSuchInstance and noSuchObject types.
- SET Command Responder fixed to obscure access to non-existing variables
by returning notWritable error (SF bug #1764839).
- AsynsockDispatcher.setSocketMap() method added to facilitate pysnmp
transport integration into third-party asyncore-based applications.
- Fix to errorIndex generation at CommandResponder application, the value
should be a one-based.

Mon Apr 23 2007 James Oakley <jfunk@funktronics.ca> - 4.1.7-1
- Update to 4.1.7
- Low-level debugging facility implemented
- Support UdpTransportTarget timeout and retries parameters in oneliner API
- Fix to snmpTrapOID construction at ...proxy.rfc2576.v1ToV2()
function
- Fix to MibViewController.getNodeName() to take MIB module name
into account (SF bug #1505847)
- Do explicit check for Counter32,Unsigned32,TimeTicks,Counter64 value types
in MibTableRow index convertion and in TextualConvention.prettyPrint()
methods (SF bug #1506341). Handle Bits in indices as RFC2578 suggests
- Apply read-create column status to libsmi2pysnmp-generated code
whenever MIB text specifies that (SF bug #1508955)
- Honor and apply DISPLAY-HINT specification when building TextualConvention
class at libsmi2pysnmp
- Managed Objects Instances files (smi/mibs/instances/) are now
double-underscore prefixed to make them imported explicitly by these
prefixed names. They used to be imported as a side-effect of
Managed Objects files import what is way too hackerish
- The libsmi2pysnmp now supports future libsmi bugfix that would generate
"ranges" subtree along with the legacy and ambiguous "range" one
- SMI support for fixed-length string indices implemented (SF bug #1584799,
- Managed Object Instances may now have smiRead, smiWrite, smiCreate methods
to support specific value mangling. These methods, if present, would be
invoked from SNMP [Agent] core instead of conventional clone() method.
The reason is to separate trivial value duplication from specific
Instance value mangling that may have Agent-specific side effects
(such as RowStatus)
- MIB table row destruction now works (SF bug #1555010)
- LCD unconfiguration functions for oneliners implemented (SF bug #1635270)
- unloadModules() and unexportSymbols() implemented at MibBuilder
- Notification type PDU proxy code fixed to produce symmetrical
convertion
- Various SNMP engine-internal caches expiration implemented
- SMI-level access control now takes effect only if AC object is
passed to MIB instrumentation API
- LCD management code now uses generic MIB instrumentation features
- Fix to oneliner manager code to have individual UdpSocketTransport
instance per each SnmpEngine. Multithreaded apps might fail otherwise.
(SF bug ID #1586420)
- Exclude the PYSNMP_MODULE_ID symbol from MIB view index, as it may get
resolved into OID label instead of actual MIB object name
- Memory leak fixed in indices.OidOrderedDict implementation
- Fix to VACM shortcuts to let notifications and requests to co-exist
for the same user otherwise
- Fix to ...oneliner.cmdgen.UsmUserData to support non-default cyphers
- USM now uses local notion of snmpEngineBoots/Time when authoritative
and cached estimate otherwise. Also, a security fix applied to to USM
time-window verification (SF bug #1649032)
- Fix to notification objects resolution code at
NotificationOriginator.sendNotification()
- Do not raise securityLevel for USM error reports that lacks user
information, as these reports could never be cyphered (SF bug #1624720)
- Non-default BULK PDU params now actually applied
- SnmpEngineID default value generation algorithmic function changed
to allow multiple SNMP engines running on the same host
- Documentation updated
- A handful of minor fixes applied (SourceForge tracker IDs #1537592,
