We just did a major upgrade of two dependencies: [PurgeCSS](https://purgecss.com/) and [SVGO](https://github.com/svg/svgo), which changed their config format. Thus we have to do a major release of `htmlnano`. You can safely upgrade to `htmlnano@1.0.0` if you don't pass any config to `minifySvg` or `removeUnusedCss` (while used with PurgeCSS) modules. Otherwise, you have to adapt the config according to the new [PurgeCSS@3](https://github.com/FullHuman/purgecss/releases/tag/v3.0.0) and [SVGO@2](https://github.com/svg/svgo/releases/tag/v2.0.0) config format. ## [0.2.9] - 2021-04-11 ### Added - `minifyConditionalComment` support `<html>` [#125]. - Minify JS within `<script type="module">` [#135]. ### Fixed - `collapseWhitespaces` around comment [#120]. - handle `CDATA` inside script correctly [#122]. - Minify SVG correctly [#129]. ### Changed - Upgrade to terser@5 (JS minification). ## [0.2.8] - 2020-11-15 ### Added - [`removeOptionalTags`](https://github.com/posthtml/htmlnano#removeoptionaltags) [#110]. - [`sortAttributes`](https://github.com/posthtml/htmlnano#removeoptionaltags) [#113]. - `source[src]` and `srcset` support to `minifyUrls` [#117]. - [`minifyConditionalComments`](https://github.com/posthtml/htmlnano#minifyconditionalcomments) [#119]. ### Changed - Sort by frequency `sortAttributesWithLists` [#111]. - Strip more spaces in `collapseWhitespace` [#112]. - Remove `loading="eager"` from `<img>` and `<iframe>` [#114]. - Remove redundant `type` from `<script>` [#114]. - Strip whitespaces between textnode and element [#116]. ## [0.2.7] - 2020-10-17 ### Added - More aggressive whitespace removal option [#90]. - Cloudflare SSE support to `removeComments` [#94]. - Improve compression ratio by sorting attribute values [#95]. - New `minifyUrls` module [#98]. - New `removeAttributeQuotes` module [#104]. - Remove `type=text/css` for `link[rel=stylesheet]` [#102]. - Collapse `crossorigin` attributes [#107]. - Exclude excerpt comment for common CMS [#108]. ### Fixed - Keep JS inside SVG wrapped in `//<![CDATA[ //]]` [#88]. ## [0.2.6] - 2020-07-15 ### Added - Let PostHTML options to be passed. ### Fixed - `<script>` tags merging without content. ## [0.2.5] - 2019-11-09 ### Added - Option to remove unused CSS using PurgeCSS [#84]. ### Fixed - Keep the order of inline and external JS [#80]. ## [0.2.4] - 2019-07-11 ### Fixed - Remove crossorigin from boolean attribute [#78], [#79]. - Disable SVGO plugin convertShapeToPath in safe preset [#76]. ## [0.2.3] - 2019-02-14 ### Fixed - Keep `<g>` in SVG by default [#71]. ## [0.2.2] - 2019-01-03 ### Added - `removeUnusedCss` module [#36]. ### Fixed - Bug when `tag === false` [#66]. - Add `crossorigin` to boolean attributes [#67]. ## [0.2.1] - 2018-12-01 ### Fixed - Disable JS minifying on AMP pages [#65]. ## [0.2.0] - 2018-09-14 ### Breaking changes - The API of `minifyCss` module has been changed since `cssnano` has been updated to version 4, which has a different API.
