Revision history for Perl extension CSS::Minifier::XS.

0.15      2026-06-30 11:19:01-07:00 America/Vancouver
    - Fix bug which resulted in zeroes being collapsed when they shouldn't,
      affecting filenames with zeroes in them (e.g.  "url(status-0.png)").
      Thanks to Stefan Berger for reporting GH#5.

0.14      2026-06-28 16:30:59-07:00 America/Vancouver
    - Fixes a memory leak in minify(), when the entire document is minified
      away.  CVE-2026-13593

0.13      2021-02-06 17:26:39-08:00 America/Vancouver
    - Internals; avoid allocating memory for each node as we tokenize the
      document, and simply use pointers back into original string.
      - Dramatically improves performance; local testing shows boost from
        ~25MB/s to ~85MB/s
    - Improve zero value minification further
    - Simplified whitespace compaction

0.12      2021-01-30 21:46:07-08:00 America/Vancouver
    - rewrote test suite into a single ".t" test
    - GH #1 / RT #97574; whitespace before a ":" in a pseudo-selector is
      meaningful and needs to be preserved (e.g. "#link :visited")
    - Further reductions of "zero values", when possible
      - "00000px" and "0.0px" become "0px"
      - "000%" and "0.0%" become "0%"
      - units are preserved inside of functions, but eliminated otherwise, and
        percentages are always left as a percentages
    - Optimized whitespace collapsing
    - Optimized memory usage and string copying

0.11      2020-12-30 21:27:39-08:00 America/Vancouver
    - POD spelling fixes
    - Switch to DZil Author Bundle

    - RT #90879; correct minification of %s in "hsl()" and "hsla()" functions
      Thanks to Philipp Soehnlein
    - RT #103231; don't remove units on zero values inside of functions.
      Thanks to Isaac Montoya, for an additional test case.
    - No long drop units on zero percentages, as those may be required for CSS
      animations.  Thanks to Isaac Montoya for continuing to poke me on this.
    - Now prunes leading whitespace before "!important"
        e.g. "color: red !important" becomes "color:red!important"
    - Switch to Dist::Zilla

      Thanks to Philipp Soehnlein
    - RT #60239; remove WS around ">" and "~" selector combinators
      Thanks to Jacob R.

    - RT #36557: Nasty segfault on minifying comment-only css input.

      segfault, and only in certain Perl versions.
