1.4.2

2013-07-20

• if you don't pass a strict maths option, font size/line height options are output correctly again
• npmignore now include .gitattributes
• property names may include capital letters
• various windows path fixes (capital letters, multiple // in a path)

1.4.1

2013-07-05

• fix syncImports and yui-compress option, as they were being ignored
• fixed several global variable leaks
• handle getting null or undefined passed as the options object

1.4.0

2013-06-05

• fix passing of strict maths option

1.4.0 Beta 4

2013-05-04

• change strictMaths to strictMath. Enable this with --strict-math=on in lessc and strictMath:true in JavaScript.
• change lessc option for strict units to --strict-units=off

1.4.0 Beta 3

2013-04-30

• strictUnits now defaults to false and the true case now gives more useful but less correct results, e.g. 2px/1px = 2px
• Process ./ when having relative paths
• add isunit function for mixin guards and non basic units
• extends recognise attributes
• exception errors extend the JavaScript Error
• remove es-5-shim as standard from the browser
• Fix path issues with windows/linux local paths

1.4.0 Beta 1 & 2

2013-03-07

• support for :extend() in selectors (e.g. input:extend(.button) {}) and &:extend(); in ruleset (e.g. input { &:extend(.button all); })
• maths is now only done inside brackets. This means font: statements, media queries and the calc function can use a simpler format without being escaped. Disable this with --strict-maths-off in lessc and strictMaths:false in JavaScript.
• units are calculated, e.g. 200cm+1m = 3m, 3px/1px = 3. If you use units inconsistently you will get an error. Suppress this error with --strict-units-off in lessc or strictUnits:false in JavaScript
• (~"@var") selector interpolation is removed. Use @{var} in selectors to have variable selectors
• default behaviour of import is to import each file once. @import-once has been removed.
• You can specify options on imports to force it to behave as css or less @import (less) "file.css" will process the file as less
• variables in mixins no longer 'leak' into their calling scope
• added data-uri function which will inline an image into the output css. If ieCompat option is true and file is too large, it will fallback to a url()
• significant bug fixes to our debug options
• other parameters can be used as defaults in mixins e.g. .a(@a, @b:@a)
• an error is shown if properties are used outside of a ruleset
• added extract function which picks a value out of a list, e.g. extract(12 13 14, 3) => 3
• added luma, hsvhue, hsvsaturation, hsvvalue functions
• added pow, pi, mod, tan, sin, cos, atan, asin, acos and sqrt math functions
• added convert function, e.g. convert(1rad, deg) => value in degrees
• lessc makes output directories if they don't exist
• lessc @import supports https and 301's
• lessc "-depends" option for lessc writes out the list of import files used in makefile format
• lessc "-lint" option just reports errors
• support for namespaces in attributes and selector interpolation in attributes
• other bug fixes

• if a mixin guard stops execution a default mixin is not required
• units are output in strings (use the unit function if you need to get the value without unit)
• do not infinite recurse when mixins call mixins of the same name
• fix issue on important on mixin calls
• fix issue with multiple comments being confused
