Changes  view on Meta::CPAN

  "Can't call method 'send_pdu' on an undefined value" error when the 
  module is loaded using a quoted eval statement. 

RELEASE 4.0.0 NOV-09-2001

- The module has been completely redesigned to add support for SNMPv3 
  and to follow the SNMP Management Framework defined by RFC 2571.
- Perl version 5.6.0 or greater is now required to use the module.
- Updated the method calls to expect the same argument syntax regardless 
  of whether they are invoked by "blocking" or "non-blocking" objects. 
- The non-core modules Crypt::DES, Digest::MD5, Digest::SHA1, and 
  Digest::HMAC are now required to support SNMPv3.
- Added the ability to specify the local address and port number used by
  each object.

RELEASE 3.65 SEP-09-2001

- Corrected an error in the Net::SNMP::FSM module that would cause all
  response messages to be dropped in "non-blocking" mode if there is
  a recv() error.
- Updated the logic in the "blocking" response handling method such

        c.  Copy or move the entire directory structure (including 
            files) located under the lib/Net directory in the 
            distribution into a directory named Net in a Perl library 
            directory.

REQUIREMENTS

    Net::SNMP uses syntax that is not supported in versions of Perl 
    earlier than v5.6.0. 

    The non-core modules Crypt::DES, Digest::MD5, Digest::SHA1, and 
    Digest::HMAC are needed to support SNMPv3.

    In order to support the AES Cipher Algorithm as a SNMPv3 privacy 
    protocol, the non-core module Crypt::Rijndael is needed.

    To use UDP/IPv6 or TCP/IPv6 as a Transport Domain, the non-core 
    module Socket6 is needed.
