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) => 14
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

browser and server url re-writing is now aligned to not re-write (previous lessc behaviour)

rootpath option can be used to add a base path to every url

hsv, hsva, unit functions

when using % with colour functions, take into account a colour is out of 256
when doing maths with a % do not divide by 100 and keep the unit
allow url to contain % (e.g. %20 for a space)
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
tolerate multiple semi-colons on rules
ignore subsequant @charset
