Version 3.5.14a: CHANGES since Version 3.5.13a
==============================================

* Fixed: Compilation problem in agentpp_config_mib.cpp
* Added: Sparse table test MIB implementation to 
  agentpp_test_mib.cpp of the ATM example agent.

* Changed: Mib constructor with persistency path
  parameter.
  The type of the parameter has been changed
  from "const char*" to "const OctetStr&".
  Access method and member "persistent_objects_path"
  are no longer static! 
* Fixed: Incorrect error check in snmpTargetAddrTMask
  that prevent modifying the row while 
  notInService(2).
* Fixed: Check whether a snmpTargetAddrTable row 
  can be set active when using createAndWait(5).
* Added: IPv6 support for the snmpTargetAddrTable.
  This includes support for the new Transport Domain
  OIDs defined in the TRANSPORT_ADDRESS_MIB.
* Added: AGENTPP_CONFIG_MIB that allows to configure
  logging levels at runtime and source address
  validation for SNMPv1/v2c protocols (see the ATM
  example or just add 
  "mib->add(new agentpp_config_mib());" to your 
  agent).

Version 3.5.13a: CHANGES since Version 3.5.12g
==============================================

* Fixed: Prefix match for context was incorrect
  implemented, since the OctetStr::operator==
  had been fixed in order to compare all bytes of
  octet strings.

* Fixed: An authorizationError has been returned
  on a notInView VACM exception on GET requests
  instead of returning noSuchObject or noSuchNam
  (SNMPv1).
* Fixed: In some cases there were variables 
  returned for some subrequests although the
  request (typically a GET request) failed because
  of an error.
* Fixed: Views created on runtime were not 
  immediately effective.
* Fixed: Setting the privacy protocol to 
  usmNoPrivProtocol via SNMP was no longer possible
  in v3.5.12d - v3.5.12g. 


Version 3.5.12g: CHANGES since Version 3.5.11c
==============================================

* Improved: Examples now use the 
  Snmp::socket_startup() on Win32 platforms.

* Added: Some error checking for assignment
  operators.
* Fixed: usmUserTable accept all registered auth
  and priv protocols.
* Fixed: Compilation problem with _SNMPv3 not
  defined in agentgen/agent/src/agent.cpp and
  the corresponding counter part of the 
  simulation agent template.

* Fixed: Compilation problems introduced by the
  latest fix (v3.5.12d) for request.cpp when 
  _SNMPv3 was disabled.

* Fixed: For notInTimeWindow authentication 
  failures no authenticationFailure notification
  will be generated by default.
 
* Fixed: AuthenticationFailure notification was
  not send on some SNMPv3 authentication 
  failures.

* Fixed: Memory leak when deserializing MibLeaf.
* Fixed: Memory leak and inconsistent calling
  sequence when a row was created using the
  RowStatus TC. The cleanup_set_request 
  (undo_set_request) method was not called 
  for all relevant sub-requests.
* Improved: snmpTargetAddrExtEntry::set_row
  now uses OctetStr instead const char* which
  allows to specify addresses containing 0.  
* Fixed: Missing end_synch() statements in
  snmpTargetAddrExtEntry::passes_filter().

* Fixed: Compilation problem with new 
  Mib::get_boot_counter method when _SNMPv3 not
  defined.

* Added: Mib::get_boot_counter and 
  Mib::set_boot_counter to persistently store
  the SNMPv3 boot counter. This is a wrapper
  for the related SNMP++ functions.
* Added: DateAndTime is now also compiled for
  Win32 environment.
* Changed: snmp_pp_ext.cpp to meet changes in
  SNMP++v3.2.7.

Version 3.5.11c: CHANGES since Version 3.5.10c
==============================================

* Fixed: Compilation problem in snmp_pp_ext.cpp
  when SNMP_PP_IPv6 was defined.

* Fixed: Incorrect use of NO_STATIC_REQUEST_LIST
  instead of STATIC_REQUEST_LIST in mib.cpp.

* Changed: v3.5.11 requires SNMP++v3.2.6a or
  later.
* Improved: Removing redirections in request
  processing to RequestList (now performance).
* Changed: Made requestList member of Mib
  non-static by default. If you need a static
  request list, then define STATIC_REQUEST_LIST.
  PLEASE NOTE: AgentX++ users should upgrade to
  v1.4.7a before upgrading AGENT++ to v3.5.11!  


Version 3.5.10c: CHANGES since Version 3.5.9a
=============================================

* Fixed: Removed redundant check for setting 
  non-default values in created rows from 
  MibTable::ready.
* Changed: Moved VC++ project files in a 
  separate project.
* Fixed: Array bounds check in List.h  
  (Array::overwriteNth()). 

* Improved: Socket handling in snmp_pp_ext.cpp

* Fixed: Synchronized class for WIN32 platform.
  Error codes returned by WaitForSingle objcect
  were not handled correctly.

* Fixed: Initialization of local engine ID
  for proxy forwarder. 
* Changed: Methods to process requests (class
  Mib) are now public. 
* Added: NotificationSender interface to
  standardize sending notifications. The Mib
  class now has a "notify" method that should
  be used to send traps/notifications. By 
  default, it uses a NotificationOriginator
  (which also implements the NotificationSender
  interfaces).
* Added: NotificationType interface as common
  interface for all trap/notification 
  implementations.
* Fixed: Opaque::get_syntax did no longer 
  override OctetStr::get_syntax because the
  latter was made const. As a consequence, 
  Opaque behaved like OctetStr. For future
  development, the OpaqueStr class of SNMP++
  should be used.

Version 3.5.9a: CHANGES since Version 3.5.8c
============================================

* Improved: LockQueue used by Request is no
  longer static. It is allocated when needed,
  but has to be freed manually.

* Added: Methods to access the number of
  entries and MibGroup instances.
* Changed: request.cpp to match new 
  Snmp::report signature in SNMP++v3.2.4.
* Fixed: Constructors of Mib now access v3MP
  via requestList member instead v3MP::I.  

Version 3.5.8c: CHANGES since Version 3.5.8
===========================================

* Fixed: Linking problems with g++3.2 due to 
  "extern" declaration of template 
  instantiations.

* Fixed: Segmentation fault when running
  AgentX++ subagent without v3MP initialized
  and _PROXY_FORWARDER defined (which is the 
  default).

* Fixed: Compilation problems without _SNMPv3
  defined.
* Note: New Makefiles assume that you have
  defined _USE_LIBTOMCRYPT when a "crypt"
  directory is present in the same folder as
  the "snmp++" and "agent++" directories. 

Version 3.5.8: CHANGES since Version 3.5.7c
===========================================

* Fixed: Compilation problems on some systems
  with template initialization.
* Improved: Support for table augmentation has
  been improved. MibTable::fire_row_changed no
  longer locks listening tables. Instead, 
  all tables that listen for a table's row 
  events are now locked during request
  processing. 
* Fixed: Could create rows for 
  snmpTargetAddrExtEntry without creating the
  corresponding row in snmpTargetAddrEntry.
* Fixed: Memory leak when failing to create a
  new row with RowStatus.
* Fixed: GETBULK TooBig error handling.
* Changed: Changed v3
* Added: Support for AES encryption. It needs
  libtomcrypt installed. It can be downloaded
  from SNMP++v3.x download page located at 
  http://www.agentpp.com 
  LibTomCrypt is originally distributed from
  http://www.iahu.ca:8080/libcrypt.html
  The examples try to link against this package.
  If you do not want to use it, remove 
  "-libtomcrypt" from common.mk.


Version 3.5.7c: CHANGES since Version 3.5.6d
============================================

* Fixed: Unfortunately, during DLL modifications
  two important methods had been removed from
  the Array template. These are required at
  least by AgentX++ and have been included
  again.

* Fixed: DLL support for VC++ did not allow
  static linking.
* Fixed: TooBig errors are now reported 
  correctly even for SNMPv3. In addition, 
  GETBULK responses now have the correct
  size in all cases.

* Added: VC++.NET project files and DLL
  support.

* Fixed: Destructor of Thread did not join 
  itself when the thread has stopped running.
  This could have caused a memory leak.
* Changed: Changed v3_mib.cpp to be compatible
  with SNMP++v3.2.2.

Version 3.5.6d: CHANGES since Version 3.5.6b
============================================

* Fixed: Possible memory leak in AgentLog
  when using dynamically created threads.
* Improved: Compilation on Cygwin.
* Fixed: Array bounds read in 
  notification_log_mib.cpp line 1263.

* Fixed: Daylight savings time bug in 
  DateAndTime::update().

Version 3.5.6b: CHANGES since Version 3.5.6a
============================================

* Fixed: MibTable::remove_row caused
  segmentation fault when specified row was
  not part of the table.
* Changed: Opaque::get_syntax() to const.
* Changed: snmp_pp_ext.h according to SNMP++
  v3.2.1c

Version 3.5.6a: CHANGES since Version 3.5.5b
============================================

* Fixed: Renamed MibGroup::is_persitent to
  MibGroup::is_persistent.
* Fixed: DateAndTime in 
  snmp_textual_conventions.cpp
* Fixed: MibLeaf::set_value(unsigned long)
  changed syntax to INT32 instead to UINT32.

Version 3.5.5b: CHANGES since Version 3.5.5a
============================================

* Improved: Some cleanups (#include, const).

Version 3.5.5a: CHANGES since Version 3.5.5
===========================================

* Fixed: Removed const from Request::get_oid
  which has broken AgentX++ request handling
  with AGENT++ v3.5.4.
* Fixed: MibTable::find_succ was not 
  synchronized which could cause race
  conditions when updating table (removing
  rows) from MibTable::*_request methods.
  Updating from MibTable::update was OK.
* Fixed: MibStaticEntry::find_succ was not
  completely protected by synchronization.
* Fixed: Mib::next_access_control did not
  lock a table when getting successor leaf.

Version 3.5.5: CHANGES since Version 3.5.4a
===========================================

* Added: Example implementation in 
  NotificationOriginator to add v2c trap
  destination.
* Added: INSTALL file which describes how to
  setup AGENT++ with SNMP++ and AgentGen 
  Pro.
* Improved: agent.cpp for simulation agents.
* Cleanup: agent_copy.cpp

Version 3.5.4a: CHANGES since Version 3.5.4
===========================================

* Fixed: Thread::wait(ulong millis) did 
  compute nsec part of time to wait 
  incorrect.

* Added: Vacm::get_vacm_tables() to get the
  pointers of to the SNMP tables used by the
  VACM.

Version 3.5.4: CHANGES since Version 3.5.3a
===========================================

* Requires SNMP++v3.2 or later, if _SNMPv3 
  is defined in "snmp++/include/config.h".

* Changed behavior when committing a SET
  request fails. The error status returned
  by "commit_set_request" is now returned
  as error status of the request, instead
  SNMP_ERROR_COMITFAIL in case of any error.

* Improved: Undoing of SET requests. 

* Fixed: Wrong error status returned when
  setting usmKeyChange object with 
  uninitialized usmCloneFrom object.

* Added: Request::search_value(..)

* Changed: Request::get_oid() to const

* Improved: Logging now follows the 
  singleton design pattern which ensures
  proper initialization.

Version 3.5.3a: CHANGES since Version 3.5.2b
============================================

* Fixed: snmp_request.cpp: Did not count 
  incoming traps (snmpOutTraps).

* Fixed: Added support for (POSIX) thread 
  implementations that do not allow a
  thread to release a lock which the thread
  does not own in FAST mode. This fixes 
  also a problem that occured on WIN32 
  operating systems which caused AgentX++
  subagents to crash when performing SET
  request in parallel on the same object or
  with some latency.
  POSIX threads FAST mode is used by default
  on UNIX systems. The new LockQueue 
  mechanism is used on WIN32 systems by
  default. See include/agent++.h

* Added: IPv6 support. SNMP++v3.2 or later
  is needed to able to use it.

* Added: Makefile.bcc provided by Luis F.
  Pollo.

Version 3.5.2b: CHANGES since Version 3.5.2
===========================================

* Fixed: request.cpp: Support for contexts
