 # [1.0.0-pre.1]
-* BREAKING CHANGES (most of these are temporary):
+* BREAKING CHANGES (see the [Migration Guide](https://github.com/Sub6Resources/flutter_html/wiki/1.0.0-Migration-Guide) for a full overview of breaking changes.):
+  * The default parser has been completely rewritten and the RichText parser has been deprecated.
   * `useRichText` now defaults to `false` (the new parser uses RichText, though)
-  * `customRender` no longer does anything (just for now). 
-  * `img` `alt` tags are no longer rendered.
-  * `table` is no longer supported.
-  * `sub` and `sup` are no longer correctly rendered.
-* `HtmlParser` has been entirely rewritten. (It now uses `RichText` extensively)
+  * `customRender` now works for the default parser.
+* Adds support for `<audio>`, `<video>`, `<iframe>`, `<svg>`, `<ruby>`, `<rt>`, `<rp>`, `<sub>`, and `<sup>`
+* Adds support for over 20 CSS attributes.
+* Fixes 22 issues (see the list at [#122](https://github.com/Sub6Resources/flutter_html/pull/122))
 * The following parameters of `Html` have been deprecated and should no longer be used:
   * `useRichText`
   * `padding`
   * `backgroundColor`
   * `defaultTextStyle`
+  * `renderNewlines`
   * `customEdgeInsets`
   * `customTextStyle`
   * `blockSpacing`
+  * `customTextAlign`
   * `linkStyle`
+  * `imageProperties`
+  * `showImages`
 * The default text style now matches the app's Material `TextTheme.body1` (Fixes [#18](https://github.com/Sub6Resources/flutter_html/issues/18)).
 * Fixed quite a few issues with `img`
 * Added a fancy new `style` attribute (this should be used in place of the deprecated styling parameters).
-* Added an even fancier new `css` attribute that takes a CSS string and applies those styles to your widgets.
