- 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.
