Changes:

4.09:
=====
- SECURITY: Applying security patch from:
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=356555 (Julien
Danjou)

4.08:
=====
- FIX: DESTROY was sometimes wiping out exception handling. RT#18183,
  Matt LeBlanc.
- SECURITY: Resolve some issues in:
  http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=356555
      - db_file and file now check for symlinks either explicitly or by
        using O_EXCL on sysopen
      - file creation umask defaults to 660
- NEW: db_file and file drivers now accepts a UMask option. (Matt
  LeBlanc)
- INTERNAL: test suite clean up (Tyler MacDonald)

4.07:
=====
- INTERNAL: MANIFEST update to fix release.

4.06:
=====
- INTERNAL: MANIFEST update to fix release.

4.06:
=====
- FIX: some stray warnings when flushing:  "Use of uninitialized value
  in numeric eq (==)" (RT#14603)
- NEW: JSON and YAML serializers (Tyler MacDonald)
- INTERNAL: CGI::Session::Test::Default accepts a "skip" argument,
  listing tests that should be skipped. (Tyler)

4.05:
=====
- FIX: Race condition fixed when writing to session files (RT#17949)

4.04:
=====
- NEW: File driver now has option to disable flock (for those running
  Win 9x, VMS, MacPerl, VOS and RISC OS). (Matt LeBlanc)
- FIX: If DBI driver wass initialized using 'Handle',
  Driver::DBI::init() returned false, and Driver::new() thought init
  faild and kept returning undef. The problem was fixed by making sure
  Driver::DBI::init() returned true. (Sherzod)
- Added .*cgisess.* to disclude cgisess.db, cgisess.id, and any session
  files created in the t directory. (Matt LeBlanc)
- FIX: File driver now respects $CGI::Session::File::FileName for 3.9x
  compatibility. (Matt LeBlanc)
- FIX: Default serializer now properly handles data structures that
  appear more than once in the serialized data structure (before it'd
  result in data structures that were equivalent but did not have the same
  address). (Matt LeBlanc)
- FIX: File driver now localizes the filehandle to avoid any possibility
  of extended locking in persistent environments (Matt LeBlanc)
- FIX: File driver now locks the file when retrieving the session data
  (Matt LeBlanc)
- NEW: DBI Drivers now support a lazy loaded database handle. This is
  useful with the CGI::Application plugin system. If the session is
  never used, the database handle may not not need to be created. The
  syntax is to use a code ref: Handle => sub {DBI->connect} (Mark
  Stosberg)

 Finally, be aware that since 4.0 some people have reported problems
 with the auto-flushing code. There may be an unresolved. You always
 call flush() to be safe. Input or code contributions for the issue
 are appreciated. Some related tickets include:
