	* Release 1.0703.
	
	* This minor release deals with some more "ambiguous call" warnings of the 
	sort that release 1.07 addressed, since I didn't get to them all in 1.0702.  
	Both modules are now at version 1.0703.  In CGI::MultiValuedHash, the POD 
	was updated in Synopsis and The Default File Format; for the latter case, I 
	hope that I removed ambiguity regarding how compatible my default file 
	format is with Boulderio.  Thanks to Jonathan Snyder 
	<jonathan@mail.method.com> for alerting me to the fixed problems.

	* Release 1.0702.
	
	* This minor release deals with some more "ambiguous call" warnings of the 
	sort that release 1.07 addressed, since I didn't get to them all that time.  
	There are also minor POD updates in this release.  Both modules are now at 
	version 1.0702.

	* Release 1.0701.
	
	* This release should take care of some install problems because the modules 
	are now inside folders like lib/CGI and lib/Data whereas they were just in 
	CGI and Data before.  Thanks to Jost (kriegjcb@CMC01SE.rz.ruhr-uni-bochum.de) 
	for alerting me to this problem.  I'm afraid I still don't know much about 
	Makefiles.

	* Release 1.07.
	
	* This release should take care of a number of warnings like 
	"Ambiguous call resolved as CORE::values()" which appear on some systems 
	when -w is used.  These spring from the fact that Data::MultiValuedHash 
	has methods with the same names as the following built-in functions: keys(), 
	values(), exists(), push(), unshift(), pop(), shift(), delete().  To fix 
	this, I have changed all such calls to built-in functions so that they 
	explicitely say CORE::*.  However, the modules were working before, as Perl 
	seemed to be resolving the ambiguity in the correct way.

	* Thanks to Geir Johannessen (geir.johannessen@nextra.com) for alerting me 
	to the above warnings.

2001-03-17   Darren Duncan <perl@DarrenDuncan.net>

	* Release 1.06.
	
	* This release is the first one that includes the CPAN standard file
	"test.pl", which was created following the previous release.  The install 
	instructions in the ReadMe file were updated to reflect that "make test" 
	should now work.  "Test.pl" was used to discover several bugs that my 
	production use of the modules didn't; their fixes are detailed below.
	
	* Removed gratuitous arguments from clone() that allowed one to specify a 
	subset of keys for the clone to have.  This way, clone() is fully standard 
	and does what one would intuitively expect, namely make an identical copy.
	
	* Added new method fetch_mvh() to Data::MultiValuedHash which replaces the 
	functionality dropped from clone().  fetch_mvh() has the same calling 
	conventions as fetch_all(), except that an MVH object is returned instead of 
	a literal hash of array refs.
	
	* Fixed bug in Data::MultiValuedHash where the store_all() method didn't 
	properly handle the import of case-sensitive keys into a case-insensitive 
	MVH.  Specifically, keys were added but associated values were lost.
	
	* Fixed bug in Data::MultiValuedHash where the splice() method didn't 
	properly handle missing LENGTH arguments.  That is, if one called 
	"splice( KEY, -1 )" then that should remove the last element of the array, 
	but it instead acted like LENGTH had a value of 0, so nothing was removed 
	or returned.  This issue appears to be related to Perl's built-in splice 
	function, which treats "splice( KEY, 1 )" and "splice( KEY, 1, undef )" or 
	"splice( KEY, 1, () )" differently.  So the fix for my splice() method 
	involved having two separate calls to Perl's splice() depending on whether 
	its OFFSET argument is defined or not.
	
	* Added several new POD sections to the end of CGI::MultiValuedHash that give 
	an overview of using url-encoding/decoding and file-import/export features, 
	mainly describing what the file format or encoding formats look like.
	
2001-03-14   Darren Duncan <perl@DarrenDuncan.net>

	* Release 1.0501.
	
	* Fixed bug in CGI::MultiValuedHash where the method to_html_encoded_table() 
	was misnamed as to_html_encoded_hidden_fields(), which is the same as a 
	separate method that also exists.  This module's version was increased to 
	1.0501 to reflect the change.
	
2001-03-08   Darren Duncan <perl@DarrenDuncan.net>

	* Release 1.05.
	
	* Added method splice() to Data::MultiValuedHash so as to round out the set 
	of standard array manipulation functions.
	
	* Added static function batch_new() to Data::HashOfArrays which emulates the 
	symantecs of calling new() multiple times with a list of initializers; as 
	many new MVH objects are made as there are elements in the list.
	
	* Added programmer documentation to the private method 
	_reduce_hash_from_subset() so people know how to use this method.  Due to its 
	private nature, it is not covered in the POD.
	
	* Added static functions batch_to_file() and batch_from_file() to 
	CGI::MultiValuedHash so that an entire list of MVH objects can be written to 
	or read from a file at once.  Symantecs are similar to calling the to_file() 
	and from_file() methods.  batch_from_file() will read to the end of the file 
	by default, but can be restricted by an argument to stop after a certain 
	number of objects are retrieved.

2001-03-07   Darren Duncan <perl@DarrenDuncan.net>

	* Release 1.04.
	
	* This release is the first one that includes the CPAN standard files 
	"Makefile.PL" and "MANIFEST", which were all created following 
	the previous release.  The content of "Manifest" was previously inside the 
	"ReadMe" file.  Improved the install instructions in my ReadMe file.
	
	* Added a hook to the initialize() method in Data::MultiValuedHash for 
	handling initializers that aren't hashes.  CGI::MultiValuedHash now uses 
	that hook for handling more initializer types, rather than overloading all 
	of initialize().
	
	* Many small changes were made to methods in Data::MultiValuedHash so that 
	they work better or the code is more readable.
	
	* Added "Method Relationship Overview" section to the POD of Data::MVH.
	
	* Changed the ignores_case() method so that you can now change that property.
	When changing this property from false to true, any existing keys are 
	lowercased, which can not be reversed (except from a backup).
	
	* Added method fetch_hash() to Data::MVH which returns a hash containing 
	all of the keys and one for each; values are all taken from the array 
	index specified with an argument.  fetch_first() and fetch_last() have 
	been changed to use this to implement themselves, since they are the same 
	except with implicit indexes of 0 or -1.
	
	* Added INDEXES argument to fetch() and fetch_all() so that a caller can 
	restrict a range of values to be returned for each key, much as the KEYS 
	argument of some methods restrict which keys are returned; the new argument
	does not have a COMPLEMENT modifier, however. 
	
	* Added a method to CGI::MultiValuedHash for outputting the object's keys 
	and values in an HTML table.

2001-01-03   Darren Duncan <perl@DarrenDuncan.net>

	* Release 1.03.
	
	* This release is the first one following official registrations with 
	"The Perl 5 Module List".  The updated entries would look like this:
	
Data::
::MultiValuedHash bdpO Hash whose keys have multiple ordered values DUNCAND

CGI::
::MultiValuedHash bdpO Store and manipulate url-encoded data        DUNCAND
	
	* This release contains my "Data::MultiValuedHash" and "CGI::MultiValuedHash" 
	modules, which were previously a part of the following distributions 
	under the temporary name of "CGI::HashOfArrays":
		- "libdwg": v1.0 r2000-07-23, v1.11 r2000-08-23
		- "CGI-FormGenerator": v0.9 r2000-09-04, v0.9201 r2000-12-26
	
	* These modules require Perl version 5.004.

	* Code changes since CGI::HashOfArrays consist mainly in its separation into 
	two modules, named above.  This took care of a longstanding logistical 
	problem concerning whether the module was a generic data structure 
	or a tool for encoding/decoding CGI data.  The CGI:: module is a subclass of 
	the Data:: module, so you can use it like you used the old module.
	Thanks to Johan Vromans <jvromans@squirrel.nl> for suggesting the split.
	
	* The POD also received significant updates.  Thanks to Steve Benson 
	<steve.benson@stanford.edu> for suggesting improvements to initialize().
	
	* Added method store_value() to Data::MultiValuedHash.
	
2000-12-26   Darren Duncan <perl@DarrenDuncan.net>

	* CGI-FormGenerator 0.9201, the last version of any distribution to include
CGI::HashOfArrays, was released.
	
2000-07-23   Darren Duncan <perl@DarrenDuncan.net>

	* libdwg 1.0, the first version of any distribution to include
CGI::HashOfArrays, was released on CPAN.
