	  + moved Custom Authentication Mechanisms toward end
	  + recommended use of scalar context due to historical API behavior

version 3.26: Mon Jan 31 22:15:04 EST 2011
	- *require Perl 5.8.1 as constant use is invalid on 5.6
	- rt.cpan.org#63524: fetch_hash() parse errors
	  [Brian Kroth]
	  + fixed handling of LITERAL values in response
	  + fixed handling of field names with a dash (e.g. X-SAVEDATE)
	  + fetch_hash now uses Escaped_results() method
	- *fixed Escaped_results() to properly join LITERAL data with
	  the data that comes before and after it
	- *rt.cpan.org#60945: append_file() does not interpret $date as expected
	  [Jason Long]
	  $date should now be 1 (to use the file mtime) or a valid RFC3501 date
	- *rt.cpan.org#61292: memory consumption with message_string()/append()
	   rt.cpan.org#61806: Major problem with one function in IMAPClient
	  [Gilles Lamiral, Casey Duquette]
	  + use @_ / $_[<num>] in critical places to avoid pass by
	    value memory overhead
	  + use in memory files in a few critical places as that code
	    path in Mail::IMAPClient is significantly more efficient
	    with internal memory usage
	  + *new (undocumented/do-not-use-without-good-reason)
	    attribute Maxappendstringlength used by append() and
	    append_string() holds the size (in bytes, default 1 MiB)
	    that triggers when message SCALAR(s) passed to these
	    methods will be treated as an in memory file.  This
	    attribute will likely be removed in a future version.
	  + *append() and append_string() now call append_file() and
	    use an im memory file when length($message) is greater
	    than Maxappendstringlength; other minor code cleanup
	  + *message_string() now calls message_to_file() and uses an
	    in memory file
	  + refactor message_to_file() to use internal _imap_uid_command()
	  + update _read_line() to be more efficient w/CPU in critical
	    section by pulling isa() checks out of main loop also
	    conserve memory by not storing an extra copy of LITERAL
	    data if the data was put into a filehandle from the caller
	  + Memory/working set (KB) comparison (Perl 5.10 cygwin Win7):
	    - test: message_string on 6.1M msg and then append 6.1M msg
	      version | start | after message_string | after append
	      --------+-------+----------------------+-------------
	        2.2.9 |  7624 |                74404 |       131896
	         3.25 |  7716 |                74408 |       156532
