+YUI Compressor 2.4.2, 2008-11-10
+--------------------------------
+
++ Preserved comments shouldn't prevent obfuscation (Thanks to Matjaz Lipus)
+
+YUI Compressor 2.4.1, 2008-10-28
+--------------------------------
+
++ Use preferentially lower case letters for obfuscated variable names.
+ Since JavaScript keywords use lower case letters most often, this
+ improves the efficiency of any compression algorithm (gzipping)
+ used after minification.
++ Don't append a semi-colon at the end of a JavaScript file when the
+ last token is a special comment.
+
+YUI Compressor 2.4, 2008-10-21
+------------------------------
+
++ Allowed the YUI Compressor (which uses a modified version of Rhino)
+ to work alongside the original (unmodified) rhino library by using
+ a custom class loader.
++ Added all that's necessary to build the YUI Compressor to the
+ downloable package.
++ Fixed unnecessary white space after return / typeof when possible.
+
+YUI Compressor 2.3.6, 2008-07-10
+--------------------------------
+
++ Fixed a few minor bugs with the CSS compressor
++ Changed packaging. The original Rhino library, which is used to build the
+ YUI Compressor, is not part of the downloadable archive. Too many people
+ put it in their classpath, generating a lot of invalid bugs.
+
+YUI Compressor 2.3.5, 2008-02-08
+--------------------------------
+
++ Added a warning when more than one 'var' statement is used in a single scope.
+ Automatic coalescence is extremely complicated, and would be unsafe if not
+ done properly.
+
+YUI Compressor 2.3.4, 2008-02-07
+--------------------------------
+
++ Expanded the list of reserved words used by isValidIdentifier()
+
+YUI Compressor 2.3.3, 2008-02-04
+--------------------------------
+
++ C-style comments starting with /*! are preserved. This is especially
+ useful with comments containing copyright/license information.
+
+YUI Compressor 2.3.2, 2008-02-01
+--------------------------------
+
++ Compressing an empty JS file throws an error [SourceForge bug #1884207]
++ When a string is the first token in a function body, it was removed from
+ the compressed file [SourceForge bug #1884314]
+
+YUI Compressor 2.3.1, 2008-01-30
+--------------------------------
+
++ Added test against list of reserved words in method isValidIdentifier.
+
+YUI Compressor 2.3, 2008-01-28
+------------------------------
+
++ Always output a ';' at the end of a minified JavaScript file. This allows
+ the concatenating of several minified files without the fear of introducing
+ a syntax error.
++ Removed all System.exit() statements. Throw exceptions instead. This is
+ especially useful when running the compressor from within a J2EE container.
+ [SourceForge bug #1834750]
++ Transform obj["foo"] into obj.foo whenever possible, saving 3 bytes.
++ Transform 'foo': ... into foo: ... whenever possible, saving 2 bytes.
++ Added support for multi-line string literals [SourceForge bug #1871453]
++ Added support for unescaped slashes inside character classes in regexp.
++ Minor performance improvements.
++ Preserve the escaping for an octal representation of a character in string
+ literals [SourceForge bug #1844894]
+
+ var a = '\001';
+
++ CSS: Preserve comments that hide CSS rules from IE Mac:
+
+ /* Hides from IE-mac \*/
+ ...
+ /* End hide from IE-mac */
+
++ CSS: Added support for box model hack [SourceForge bug #1862107]
+
+ div.content {
+ width:400px;
+ voice-family: "\"}\"";
+ voice-family:inherit;
+ width:300px;
+ }
+
+YUI Compressor 2.2.5, 2007-10-09
+--------------------------------
+
++ Remove line terminator after escape in string literals.
+
+YUI Compressor 2.2.4, 2007-10-01
+--------------------------------
+
++ Fixed the way quote characters are counted in string literals
+ [SourceForge bug #1804576]
++ Do not use a regular expression using non-greedy matching to remove CSS
+ comments (if the comment is more than 800 characters long or so, a stack
+ overflow exception gets thrown) Instead, use good old parsing...
++ Fix unnecessary quote escaping in string literals.
+
+YUI Compressor 2.2.3, 2007-09-28
+--------------------------------
+
++ Transform </script into <\/script instead of replacing all </ into <\/.
++ Fixed bug related to the shortening of hexadecimal color codes (the string
+ "1px solid #aabbcc" became "1px solid#abc", missing a required white space)
++ Added --preserve-strings option to specify that concatenated string literals
+ should never be merged.
++ Do not convert \uXXXX and \xXX escape sequences to their unicode equivalent.
+
+YUI Compressor 2.2.2, 2007-09-27
+--------------------------------
+
++ Fixed regression related to the optimization of the amount of escaping
+ in string literals and the concatenation of string literals.
++ Modified the Rhino tokenizer to handle JScript conditional comments
+ natively (instead of hacking around the fact that Rhino is not keeping
+ track of comments)
++ Transform </ into <\/ in string literals. This is especially useful if the
+ code is written to a script block in an HTML document. This renders the old
+ hack '<scr'+'ipt ...><'+'/script>' completely useless.
++ When converting decimal rgb color values to hexadecimal color values,
+ prepend a '0' if the value is less than 16. Otherwise, rgb(0,124,114)
+ for instance becomes #07c72, which is incorrect.
++ In CSS files, do not change color names into their corresponding color
+ codes (and vice-versa) due to the high potential of introducing bugs
+ (rolled back from 2.2.1)
+
+YUI Compressor 2.2.1, 2007-09-25
+--------------------------------
+
++ Optimize quote escaping in JavaScript string literals by using the best quote
+ character (' or " depending on the occurrence of this character in the string)
++ Fixed minor bug in the CSS compressor. Colors should not be shortened in
+ filter: chroma(color="#FFFFFF");
+ Otherwise, it makes the filter break in Internet Explorer.
++ In CSS files, change color names into their corresponding color codes
+ (and vice-versa) if that change yields any savings.
+
+YUI Compressor 2.2, 2007-09-18
+------------------------------
+
++ Don't obfuscate function argument named $super if it is the first function
+ argument listed. This is to support Prototype 1.6's heretic implementation.
++ Added support for stdin/stdout (see README for more info)
++ Shorten colors from rgb(51,102,153) to #336699 in CSS files.
++ Shorten values from 0.8em to .8em in CSS files.
++ Added support for Internet Explorer's conditional comments in JavaScript
+ files. Note that the presence of a conditional comment inside a function
+ (i.e. not in the global scope) will reduce the level of compression for the
+ same reason the use of 'eval' or 'with' reduces the level of compression
+ (conditional comments, which do not get parsed, may refer to local variables,
+ which get obfuscated) In any case, the use of Internet Explorer's conditional
+ comment is to be avoided.
+
+YUI Compressor 2.1.2, 2007-08-31
+--------------------------------
+
++ Added --preserve-semi option
++ Modified --line-break option
+
+YUI Compressor 2.1.1, 2007-08-30
+--------------------------------
+
++ Fixed missing space in CSS background:url('foo.png')no-repeat
+ causing a background not to appear on Internet Explorer.
+
+YUI Compressor 2.1, 2007-08-29
+------------------------------
+
++ Pass the --line-break option to the CSS compressor.
++ Allow the output file to overwrite the input file (with version 2.0,
+ in this case, the output file was always empty)
++ Remove spaces before and after '(' and ')' as in background:url('xxx');
++ Merge (if possible) string literals that are appended in JavaScript files.
+ This not only makes the code smaller, it makes the code faster,
+ but allows you to maintain some readability in your source code.
++ Handle constructs such as a + ++ b or a + + "1" (in which case the
+ space between the operators must be kept!) and other similar cases...
++ Pass ErrorReporter instance to the constructor of class JavaScriptCompressor
+ (as suggested by David Bernard for his integration of the YUI Compressor
+ as a maven plugin)
+
+YUI Compressor 2.0, 2007-08-27
+------------------------------
+
++ Switched from Rhino 1.6R6 to Rhino 1.6R7
++ Integrated Isaac Schlueter's CSS compressor.
++ Refactored code to make it easier to use the compressor from a servlet
+ environment or another Java app (no need to pass in file names anymore)
++ Output a white-space character after 'throw' only when necessary.
++ Output a white-space character after 'break' and 'continue' when followed
+ by a label.
+
+YUI Compressor 1.1, 2007-08-20
+------------------------------
+
++ Java source now in package com.yahoo.platform.yui.compressor
++ Added --line-break option that adds a line feed character after each
+ semi-colon character (may help debugging with the MS Script debugger)
++ Added support for missing JavaScript features (get, set, const)
++ Do not show the entire stack trace when the input file cannot be found.
++ Removed the randomization of obfuscated symbols. When compressed code is
+ checked in CVS, unchanged files would otherwise end up being versioned.
++ Added web-based front-end to the YUI Compressor as part of the dist package.
++ Added a public entry point that makes the YUI Compressor easy to integrate
+ with an already existing Java application.
++ Simplified code by using the same parsing routines used to build the symbol
+ tree while looking for undeclared symbols.
++ Count how many times each identifier is used, and display a warning when an
+ identifier seems to be unused (code cannot safely be removed automatically)
++ Remove ';' when followed by a '}'. This yields an additional ~1.5% savings
+ on yahoo-dom-event.js compared to the JSMin version.
++ Output a white-space character after 'return' and 'case' only when necessary.
