- No more
gonzales
AST format and related code minify()
andminifyBlock()
is always return an object as result now (i.e.{ css: String, map: SourceMapGenerator or null }
)parse()
- Returns AST in new format (so called
internal
) - Dynamic scanner implemented
- New AST format + dynamic scanner = performance boost and less memory consumption
- No more
context
argument, context should be specified viaoptions
- Supported contexts now:
stylesheet
,atrule
,atruleExpression
,ruleset
,selector
,simpleSelector
,block
,declaration
andvalue
- Drop
needPositions
option,positions
option should be used instead - Drop
needInfo
option,info
object is attaching to nodes when some information is requested byoptions
options
should be an object, otherwise it treats as empty object
- Returns AST in new format (so called
compress()
- No more AST converting (performance boost and less memory consumption)
- Drop
outputAst
option - Returns an object as result instead of AST (i.e.
{ ast: Object }

1.8.1 (March 30, 2016)
- Don't remove spaces after function/braces/urls since unsafe (#289)
1.8.0 (March 24, 2016)
- Usage data support:
- Filter rulesets by tag names, class names and ids white lists.
- More aggressive ruleset moving using class name scopes information.
- New CLI option
--usage
to pass usage data file.
- Improve initial ruleset merge
- Change order of ruleset processing, now it's left to right. Previously unmerged rulesets may prevent lookup and other rulesets merge.
- Difference in pseudo signature just prevents ruleset merging, but don't stop lookup.
- Simplify block comparison (performance).
- New method
csso.minifyBlock()
for css block compression (e.g.style
attribute content). - Ruleset merge improvement: at-rules with block (like
@media
or@supports
) now can be skipped during ruleset merge lookup if doesn't contain something prevents it. - FIX: Add negation (
:not()
) to pseudo signature to avoid unsafe merge (old browsers doesn't support it). - FIX: Check nested parts of value when compute compatibility. It fixes unsafe property merging.
