2012-10-02a shy attempt to obey `width` in the beautifier; added `bracketize` option ↵Mihai Bazon
to always print brackets around if/do/while/for statements; export more options via the CLI

2012-09-27fix manglingMihai Bazon
(bug in our code prevented the mangler from using a name that was in use prior to mangling but not after it)
2012-09-26removed the "squeeze" method (it's now effectively "transform")Mihai Bazon

2012-09-25it's not safe to assume that property access is side-effect-freeMihai Bazon
(getters/setters + various browser bugs will trigger side effects; also, an exception is thrown when the expression is undefined)
2012-09-25some boolean cleanupMihai Bazon
2012-09-24Support input source mapMihai Bazon
This is useful while compressing generated code; for example compressing JS compiled by CoffeeScript (assuming you got a source map): uglifyjs2 --in-source-map generated.js.map \ --source-map uglified.js.map \ -o uglified.js The above assumes you have a "generated.js.map" file which is the source mapping between your CoffeeScript and the generated.js (compiled output from CoffeeScript). The name of the input file is not present in this example; it will be fetched from the source map (but it can be passed manually too). The output will be in "uglified.js" and the output map "uglified.js.map" will actually map to the original CoffeeScript code, rather than to generated.js.
2012-09-23properly drop mutually-referring declarations that are not otherwiseMihai Bazon

2012-09-21better support for multiple input files:Mihai Bazon
- use a single AST_Toplevel node for all files - keep original source filename in the tokens

2012-09-17only do the typeof x == "undefined" optimization if x is a symbol reference ↵Mihai Bazon
and it's declared in scope, or x is not a symbol reference.
2012-09-17moved `typeof foo == "undefined"` ==> `foo === undefined` under `--unsafe`Mihai Bazon
because https://github.com/mishoo/UglifyJS2/commit/43fd45154bac89b89330e13bd1f167e2a927a23c#commitcomment-1864505
2012-09-17fix .undeclared (it's now a function)Mihai Bazon
2012-09-17minorMihai Bazon
2012-09-17possible optimization for AST_UndefinedMihai Bazon
if undefined is defined, ;-), we replace AST_Undefined nodes to a reference to the "undefined" variable; in turn the mangler will compress it to a single letter; this helps at least on jQuery.

optimizations of if/return/continue seem to be even better now
2012-09-15other small optimization:Mihai Bazon
if (foo) continue; ...body... ==> if (!foo) { ...body ... } Only when the parent block is the target loop of the `continue` statement.

shortened to x === void 0 (or x === [][0] in unsafe mode)
