--- Change Log: -----------------------------------------------------

v0.92	2006-01-09
	Kevin Haidl (kevinh at actofmind dot com) submitted the fix for
	serializing as a double when value is larger than ((pow(2,32)/2) -1)
	
	Charles M Hall (cmhall at hawaii dot edu) also submitted a patch
	that added support for unserializing booleans and empty arrays
	
	Added session_encode()
	
	Support for session_decode() is planned for next release.

v0.91	[06-Apr-04]

	Handles boolean values. (actually not... see v0.92 notes)

v0.9	[13-Apr-04]

	Handles negative values properly.  Also correctly notices
	huge integers (>2^32) and serializes/unserializes them as doubles.
	Thanks to:
	Erlend Str?msvik [ehs (at) vorfor.no]
	Konrad Stepien [konrad (at) interdata.net.pl]

v0.8	[20-Oct-03]

	Updated NULL handling (again) so that now only a perl
	value of "\0" will be serialized as a PHP NULL.

	Removed the code that serialized perl strings equalling
	"NULL" to a PHP NULL.

	Thanks to Geraint North (geraint (at) transitive.com)
	for his comments on this point.

v0.7	[08/29/02]

	Updated NULL handling so that now any string "NULL"
	or value "\0" will serialize to proper "N;" value.

	Also, fixed a rather sneaky bug where double values
	would be unserialized as integers, and decimal point
	would be dropped :(

v0.6	[07/18/02]

	Got a request and some code to add from Julian Jares
	[jjares (at) uolsinectis.com.ar] so the module properly handles
	NULL values.

	Now, NULL values (any string that contains "null" case-insens)
	will be serialized as "N;"

	it will be unserialized as "\0", since IIRC, that's the
	equivilent of a NULL.


v0.5	[04/25/02]

	Very small change suggested by [joel (at) elserver.com]
	to support multi-line strings inside of hashes/arrays

	From Joel A. Chornik [joel (at) elserver.com]:

		On line 221 (now: ):

		I added the 's' operator the end of the regex
		to be able to send hashes and arrays with strings
		that have many lines..

		#this is a serialized hash/array
		if ( $string =~ /^a:(\d+):({(.*)})$/s )

v0.4	[10/05/01]

	Encountered a problem when serializing an arrayref
	inside of a hashref, fixed it.

	Overhauled the serialization code, was able to
	get rid of an entire subroutine and significantly
	simplify serialization by taking better advanage
	of recursion.

v0.3a	[08/31/01]

	Cleaned up the two test scripts and added some more
	helpful comments to them.

	Revised and concatenated the readme and todo/caveat files

	(no change to serialize.pm code)


v0.2a	[06/15/01]

	Added support for single values
		(previously, it only worked with array or hash)

	Added support for "double" type

	Fixed support for array-nested-in-a-hash or hash-nested-in-an-array
		previously, it would not traverse correctly
		now, something like this will work:
		my %h = ( 'hello'=>'world', 'that'=> [0,1, { 'this' => 'works'} ], );


v0.1a	[06/14/01]

	Support for hash/array is functional
