2012-10-02	"use strict";	Mihai Bazon

2012-10-02	more constant folding (for names defined with `const`)	Mihai Bazon

2012-10-02	add AST_SymbolConst for names defined with `const`	Mihai Bazon

2012-10-02	drop more unused names	Mihai Bazon

2012-10-02	a 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
2012-09-28	minor	Mihai Bazon

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

2012-09-26	some speedup and more savings from unused vars that have side effects in ↵	Mihai Bazon
	initialization
2012-09-26	compressor successfully moved to TreeTransformer	Mihai Bazon

2012-09-26	checkpoint (refactoring, WIP)	Mihai Bazon

2012-09-26	minor	Mihai Bazon

2012-09-25	more cleanups	Mihai Bazon

2012-09-25	moving code around (refactoring, WIP)	Mihai Bazon

2012-09-25	discard all \uFEFF characters (https://github.com/mishoo/UglifyJS/issues/462)	Mihai Bazon

2012-09-25	started some refactoring (WIP) -- moving squeezer to TreeTransformer	Mihai Bazon

2012-09-25	minor	Mihai Bazon

2012-09-25	it's not safe to assume that property access is side-effect-free	Mihai Bazon
	(getters/setters + various browser bugs will trigger side effects; also, an exception is thrown when the expression is undefined)
2012-09-25	some boolean cleanup	Mihai Bazon

2012-09-24	Support input source map	Mihai 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.
2012-09-24	minor tests fix	Mihai Bazon

2012-09-23	properly drop mutually-referring declarations that are not otherwise	Mihai Bazon
	referenced and have no side effects
2012-09-22	tree transformer api (WIP)	Mihai Bazon

2012-09-21	log filename in parse errors / compressor warnings	Mihai Bazon

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

2012-09-19	drop unused variables	Mihai Bazon

2012-09-19	support -c with no arguments to disable compression entirely	Mihai Bazon

2012-09-18	fixed label scope/mangling	Mihai Bazon

2012-09-18	minor	Mihai Bazon

2012-09-18	support for directives	Mihai Bazon

2012-09-18	added AST_NaN (output as 0/0)	Mihai Bazon

2012-09-17	only 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.
2012-09-17	moved `typeof foo == "undefined"` ==> `foo === undefined` under `--unsafe`	Mihai Bazon
	because https://github.com/mishoo/UglifyJS2/commit/43fd45154bac89b89330e13bd1f167e2a927a23c#commitcomment-1864505
2012-09-17	fix .undeclared (it's now a function)	Mihai Bazon

2012-09-17	minor	Mihai Bazon

2012-09-17	one more test for sequences	Mihai Bazon

2012-09-17	possible optimization for AST_Undefined	Mihai 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.
2012-09-17	empty block to empty statement: {} ==> ;	Mihai Bazon

2012-09-17	more smallish optimizations	Mihai Bazon

2012-09-17	try negating AST_Binary	Mihai Bazon

2012-09-16	some cleanup	Mihai Bazon

2012-09-16	more sequencesizing (WIP)	Mihai Bazon

2012-09-16	drop unused function	Mihai Bazon

2012-09-16	rewrite handle_if_return	Mihai Bazon
	optimizations of if/return/continue seem to be even better now
2012-09-15	other small optimization:	Mihai Bazon
	if (foo) continue; ...body... ==> if (!foo) { ...body ... } Only when the parent block is the target loop of the `continue` statement.
2012-09-15	figure out label targets	Mihai Bazon

2012-09-15	join_vars:	Mihai Bazon
	var XXX; for (var YYY; ...) ==> for (var XXX,YYY; ...)
2012-09-14	compress typeof x == "undefined" to x === undefined, which further gets	Mihai Bazon
	shortened to x === void 0 (or x === [][0] in unsafe mode)
2012-09-14	minor	Mihai Bazon
	when unsafe, compress undefined as [][0]
