Changes snmp++v3.2.9d
=====================

- Improved: Removed usage of some multi-threading 
  critical C routines (for example strtok). Although
  on many systems, these routines are multi-threading
  safe, this may not be true for some systems. 

- Fixed: High CPU usage in SNMPProcessEvents() on
  Win32 platform.

- Fixed: SNMPv1 trap sysUpTime TimeTicks where not
  decoded correctly as unsigned integer value, resulting
  in a parse error when sysUpTime > 2^31-1.
- Improved: Log levels.
- Fixed: USMUserNameTable::add_entry() did not update
  the privacy password length.

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

- Added: Two static methods Snmp::socket_startup() and
  Snmp::socket_cleanup() that initialize/cleanup
  Winsock library on WIN32 and do nothing for
  other platforms. The startup method must be
  called before creating Snmp or Address objects.

- Changed: Type of some vars in UsmUserNameTableEntry
  from uchar* to OctetStr. Check if your code uses 
  this struct.
- Changed: engineBoots and engineTime are set to 0 for
  SNMPv3 noAuthNoPriv messages.

Changes snmp++v3.2.8
====================

- Added: Support for OpenSSL.
- Fixed: Compile problem in uxsnmp.cpp. 

Changes snmp++v3.2.7c
=====================

- Fixed: Synchronization problem with mpV3::Cache.
  (Henning Eggers)

- Fixed: Memory leak in OctetStr::from_hex_string.
  (Kent Gibson)
- Changed: EventListHolder::SNMPProcessEvents() 
  param is now in milliseconds (was seconds).

- Fixed: Memory leak if an async SNMPv3 message timed
  out (Henning Eggers).
- Added: Method Snmp::broadcast_discovery() to do
  SNMP broadcast discovery. 
- Improved: Console examples now accept 0 retries,
  removed warnings with gcc 3.2, and v3MP is now
  always created.

- Added: Qt 3.1 example that demonstrates SNMP++v3
  usage with a GUI (Trolltechs Qt 3.1).
- Added: Methods to store, load, and query USM users.
- Improved: Some minor clean-ups.

Changes snmp++v3.2.6b
=====================

- Fixed: GenAddress passed IPv4 addresses as IPv6 
  addresses.
- Changed: By default IDEA is not compiled into 
  SNMP++ by default because patent licensing is
  required for commercial use. Please #define 
  _USE_IDEA if you want to compile IDEA into SNMP++.
  For more details please read also README.v3.

- Fixed: Do not add -Dsun to compile command. If
  you have problems with the SnmpCollection template
  look at the instructions in collect.h. 
- Fixed: Destroy Mutex in ~EventListHolder(). 
- Improved: Lots of cleanups for the address classes.
  This leads to the following incompatibilities to 
  former versions:
  + Enums addr_type and version_type are now inside
    class Address
  + MacAddress, IpxAddress and IpxSockAddress are no
    longer included by default, but can be enabled
    in config_snmp_pp.h 

Changes snmp++v3.2.5d
=====================

- Improved: Made AuthMD5::password_to_key more
  robust against empty passwords.
- Changed: The Win32 DLL export macros now use
  SNMP_PP_DLL instead _USRDLL.
- Changed: Moved VC++ project files in a 
  separate package. 

- Improved: Minor issues with IPv6 support.
- Improved: Socket handling.

- Fixed: uxsnmp.cpp: Detecting error from socket()
  return values.

- Fixed: Moved SNMPAddInput() SNMPRemoveInput()
  SNMPAddTimeout and SNMPREmoveTimeout to the
  class EventListHolder
- Fixed: Unique Id generation in CUDEventQueue and
  CUTEventQueue.
- Fixed: Bugs in Vb::get_value() methods that take a
  char* or unsigned char* as argument
- Added: operator+() for Oids (Alexander Gutkin)
- Improved: Cleanups in queues 

Changes snmp++v3.2.4a
=====================

- Improved: Synchronous and asynchronous SNMP
  request processing is now separated. Thus,
  the global event lists have been removed. 
  Each Snmp class now holds its own event 
  lists.
  To eliminate the use of global event lists
  a new class EventListHolder was defined. Two
  new files eventListHolder.h and 
  eventListHolder.cpp contain now declaration
  and definition of that class respectively.
  That new class is a container of former
  eventList global data structure and former
  global user defined events, user-defined 
  timeouts, notifications and all outstanding
  messages. (LiorK)
- Improved: collect.h (Bill McKinnon)
- Improved: FreeBSD 5.0 support.

- Added: Makefile.gcc_solaris for compilation
  with GNU C++ compiler on Solaris.	


Changes snmp++v3.2.3b
=====================

- Fixed: Counter64::get_printable() could print
  negative values (Yakov Y.)

- 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. 
- Fixed: Compilation problems without _SNMPv3
  defined.
- Fixed: PDU length computation for encrypted
  SNMPv3 PDUs.

- Improved: New v3MP class.
- Fixed: Estimated length calculation for 
  encoded PDU.


Changes snmp++v3.2.2d
=====================

- Fixed: Possible timeouts under heavy load
  in a multi-threaded environment. 
  [Pavel Spakovsky]

- Fixed: DLL support for VC++ did not allow
  static linking.
- Added: Computation of BER encoded length of
  a Pdu. 

- Added: VC++.NET project files and fixed DLL
  support.

- Fixed: Errors in Counter64::c64_to_ld() and
  Counter64::ld_to_c64() [Mikhail Evstiounin]

- Improved: Prepared for AES usage replacing
  libDES. 
- Fixed: Compilation problems with G++3.2
  (needs updated libDES download).

Changes snmp++v3.2.1d
=====================

- Fixed: Memory leak (40 bytes) when adding an
  user to usm.
- Improved: Some cleanups (#include, const).
- Fixed: Due to possible race condition in
  MyMakeReqId() (uxsnmp.cpp) two requests could
  get the same request id. 
- Fixed: const casting caused problems with
  AIX compiler.

Changes snmp++v3.2.1
====================

- Improved: Use zero length user name for
  SNMPv3 discovery.
- Lots of cleanups.

===================

- Fixed: Compilation problem with address.cpp on
  Solaris. 

Changes snmp++v3.2
==================

- Added: IPv6 support.
- Improved: moved the USM functions into the class
  USM. To add or delete users, you will now have to
  do the following (see usm_v3.h for more details):
     Usm *usm = mpGetUsm();
     usm->add_usm_user(...);
     usm->delete_usm_user(...);

- Fixed: Possible SegFault in notify queue
  (Lior Klibansky)
- Fixed: Timeout problem in event list (Don Dietz)
- Fixed: Don't use isdigit() for BCC (Eric Zerbib)
- Added: clear() method to SnmpCollection
- Fixed: added clone() method to Pdu class, so
  SnmpCollection<Pdu> will work again.
- Added: Make notify socket decriptor available in
  Snmp class (Don Dietz)

Changes snmp++v3.1.6c
=====================

- Fixed: mp_v3.cpp: Unsigned integer values were
  not BER decoded correctly for SNMPv3 messages.
- Fixed: Some errors when compiling with -ansi
- Improved: Class AuthPriv does no longer depend
  on USM. 

Changes snmp++v3.1.6b
=====================

- Added: BCC32 support.
- Added: DLLOPT decoration for debugprintf.

=====================

- Fixed: Agent address of v1 trap PDUs is set from
  received SNMPmessage if address is not "0.0.0.0".
- Improved: Free BSD support.
- Improved: UdpAddress performance.

- Added: Pdu::set_v1_trap_address to set v1
  trap address. If not set, SNMP++ will use the
  default host address.

=====================

- Fixed: Compilation problems with non Linux
  systems regarding *_r system calls.
- Fixed: Handling of unusual v3 msgFlags and

  type is implemented as OpaqueStr as subclass
  of OctetStr.

Changes snmp++v3.1.3i
=====================

- Fixed: ASN.1 encoding of very long OIDs
  (128 subidentifiers) could cause seg.fault.

  when waiting for synchronous requests.
  (Changed select timeout in ProcessPendingEvents 
   in eventlist.cpp from 0 to 10 usec).

- Improved: Debugging output can now be 
  redirected to a file.
