Release 1.2 – 24 Nov 2003

Type Changes By
Add URLCodec: Implements the www-form-urlencoded encoding scheme. Thanks to Oleg Kalnichevski. tobrien
Add DigestUtils: Calculates MD5 and SHA digests. Thanks to Dave Dribin, David Graham. tobrien
Fix Modified Base64 to remedy non-compliance with RFC 2045. Non-Base64 characters were not being discarded during the decode. RFC 2045 explicitly states that all characters outside of the base64 alphabet are to be ignored. Fixes CODEC-26. Thanks to Brian Ewins. tobrien

Fix Soundex.setMaxLength causes bugs and is not needed. Calling Soundex.setMaxLength() with a value of 2 or less causes the wrong answer to be returned. Since the encoding returned by Soundex is always of length 4 by definition (we do not use the '-' in as a letter-nnn separator) the need for a maxLength attribute is not needed. Deprecate the field and accessor methods. Fixes CODEC-29. ggregory
Fix Fix in Metaphone relating to the handling of the maximum code length. Members
