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>' 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.
