Commons Codec Package Version 1.3 Release Notes
86+
87+
New Features:
88+
89+
o BinaryCodec: Encodes and decodes binary to and from Strings of 0s and 1s.
90+
Issue: 27813. Thanks to Alex Karasulu.
91+
o QuotedPrintableCodec: Codec for RFC 1521 MIME (Multipurpose Internet Mail
92+
Extensions) Part One. Rules #3, #4, and #5 of the quoted-printable spec are
93+
not implemented yet. See also issue 27789. Issue: 26617. Thanks to Oleg
94+
Kalnichevski.
95+
o BCodec: Identical to the Base64 encoding defined by RFC 1521 and allows a
96+
character set to be specified. Issue: 26617. Thanks to Oleg Kalnichevski.
97+
o QCodec: Similar to the Quoted-Printable content-transfer-encoding defined
98+
in RFC 1521 and designed to allow text containing mostly ASCII characters
99+
to be decipherable on an ASCII terminal without decoding. Issue: 26617.
100+
Thanks to Oleg Kalnichevski.
101+
o Soundex: Implemented the DIFFERENCE algorithm. Issue: 25243. Thanks to
102+
Matthew Inger.
103+
o RefinedSoundex: Implemented the DIFFERENCE algorithm. Issue: 25243. Thanks
104+
to Matthew Inger.
105+
106+
Fixed bugs:
107+
108+
o The default URL encoding logic was broken. Issue: 25995. Thanks to Oleg
109+
Kalnichevski.
110+
o Base64 chunked encoding not compliant with RFC 2045 section 2.1 CRLF.
111+
Issue: 27781. Thanks to Gary D. Gregory.
112+
o Hex converts illegal characters to 255. Issue: 28455.
113+
o Metaphone now correctly handles a silent B in a word that ends in MB.
114+
"COMB" is encoded as "KM", before this fix "COMB" was encoded as "KMB".
115+
Issue: 28457.
116+
o Added missing tags in Javadoc comments.
117+
o General Javadoc improvements.
118+
119+

124+
implemented. All author tags are now "Apache Software Foundation".

Commons Codec Package Version 1.2 Release Notes
129+
130+
NEW FEATURES:
131+
132+
* URLCodec - Implements the 'www-form-urlencoded' encoding scheme
133+
134+
* DigestUtils - Simple utility class that provides static convenience
135+
methods for calculating md5 and hex digests.
136+
137+
138+
BUG FIXES:
139+
140+
* Fix for Bug 19860: Modified Base64 to remedy non-compliance with RFC
141+
2045. Non-Base64 characters were not being discarded during the
142+
decode. RFC 2045 explicitly states that all characters outside of the
143+
base64 alphabet are to be ignored.
144+
145+
* Fix for Bug 24360: Hex.decode(Object) throws a ClassCastException
146+
when a String argument is passed in.
147+
148+
* Fix for Bug 24471: Soundex: The HW rule is not applied; hyphens and
149+
apostrophes are not ignored.
150+
151+
* Fix for Bug 24484: Soundex.setMaxLength causes bugs and is not needed.
152+
Calling Soundex.setMaxLength() with a value of 2 or less causes the wrong
153+
answer to be returned. Since the encoding returned by Soundex is always
154+
of length 4 by definition (we do not use the '-' in as a letter-nnn
155+
separator) the need for a maxLength attribute is not needed. Deprecate
156+
the field and accessor methods.
157+
158+
* Fix in Metaphone relating to the handling of the maximum code length.
159+

Commons Codec Package Version 1.1 Release Notes
163+
164+

166+
This document contains the release notes for this version of the Commons
167+
Codec package, and highlights changes since the previous version. Version
168+
1.1 is the first official release of Codec. Numerous projects had been
169+
depending on Version 1.0-dev while Codec was in the Sandbox, and backwards
170+
compatibility has been preserved to ease the transition to this official
171+
release.
172+
173+
NEW FEATURES:
174+
175+
* A newer version of the Base64 class reflecting improvements from
176+
both the commons-httpclient and xml-rpc versions of code forked
177+
from catalina.
178+
* Base64 class from commons-httpclient in org.apache.commons.codec.base64
179+
has been retained for backwards compatibility but has been deprecated
180+
* Soundex class from commons-util in org.apache.commons.codec
181+
* Metaphone class from commons-util in org.apache.commons.codec
182+
* RefinedSoundex class in org.apache.commons.codec
183+
* Encoder/Decoder interfaces in org.apache.commons
184+
* String and Binary specific Encoder/Decoder interfaces in
185+
org.apache.commons
186+
* StringEncoderComparator replaces the SoundexComparator from the
187+
language package.
188+
189+
BUG FIXES:
190+
191+
* Base64 now discards whitespace characters when decoding encoded
192+
content.
