v2.6.2
HTML: ignore CSS minification for amp-boilerplate
HTML: add KeepQuotes option for attributes
XML: bugfix for recent changes to XML parser
v2.6.1
Upgrade to tdewolff/parse@2.3.14:
Re-parse input immediately when encountering parse error. Previously this was only done if the error was actually read which would save us from re-parsing the file (i.e. better performance). However, an error is (a) rare and (b) happens only once per file. Re-parsing on errors does not impact the performance of well formatted files, and a reliable error message is valued more.
Bugfix: prevent infinite loop on error on input file that contains unicode code points (i.e. any character bigger than 0xC0 usually followed by more bytes).
Improve error messages for parsers to include parser name and print offending byte(s)
v2.6.0
CSS: remove space after function in property value; margin:calc(10px) calc(20px) => margin:calc(10px)calc(20px)
SVG: parse A path command correctly when the booleans largeArc and sweep are not separated by a space, such as in A10 10 0 0120 0 which is equivalent to A10 10 0 0 1 20 0
SVG bugfix: make sure we are processing a valid path command
SVG bugfix: prevent panic when having insufficient path arguments
cmd: surpress error when minifying empty directory
HTML: only minify attributes for known HTML5 tags, fixes#270
HTML, XML, SVG: minify entities with parse@2.3.13 such as: " => ", " => ", " => ", ’ => ’, ✏ => ✏.
