+### 0.7.0
+
+- [changed] Remove some noisy stderr output when encoutering control chars
+  (thanks sftse)
+- [added] A builder-based config API.
+- [changed] Updated MSRV to 1.60
+- [fixed] Fixed #88: panic when a width of zero passed in (thanks bingen13)
+- [fixed] Fixed #90: Fixed a divide-by-zero panic with colspan=0 (thanks mtorromeo)
+- [added] Add very basic CSS colour support (under the css feature flag)
+- [changed] Removed ansi\_colours feature (from\_read\_coloured is always available)
+- [changed] Overhauled error handling.  Internally (and in the lower level
+  API) errors (mainly "TooNarrow") are passed around with `Result`.  Fixed
+  some panics and infinite loops.  (Thanks WIZeaz for fuzzing)
+
 ### 0.6.0
 
 - [changed] Improve layout of tables thanks to sftse:

+## Cargo Features
+
+|Feature| Description|
+|-------|------------|
+|css    | Limited handling of CSS, adding Coloured nodes to the render tree. |
+|html\_trace| Add verbose internal logging (not recommended) |
+|html\_trace\_bt| Add backtraces to the verbose internal logging |
+
+### CSS support
+
+When the `css` feature is enabled, some simple CSS handling is done.
+
+* The contents of \<style\> elements are parsed and some colour rules are extracted
+* Some simplified selector matching is done: currently `<span class="foo">` with
+  CSS rules similar to `.foo { color:#123456; }`.  This will add `Coloured(...)` nodes
+  to the render tree when matching.
+
+The CSS handling is expected to improve in future (PRs welcome), but not to a full-
+blown browser style system, which would be overkill for terminal output.
+
+There are two ways to make use of the colours:
+* Use `from_read_rich()` or one of its variants.  One of the annotations you may get
+  back is `Colour(..)`.
+* Use `from_read_coloured()`.  This is similar to `from_read()`, but you provide
+  a function to add terminal colours (or other styling) based on the same
+  RichAnnotations.  See examples/html2text.rs for an example using termion.
