 ### Breaking Changes:
 
+- 0.7.0 - this version introduces markdown rendering in place of returning html strings, so any usage of `formatHover` and/or `formatError` configuration will be passed to `markdown-it` which doesn't handle html by default.
 - 0.5.0 - this breaking change only impacts those following the "custom usage" approach, it _does not_ effect users using the high level, "bundled" `jsonSchema()` or `json5Schema()` modes. See the custom usages below to learn how to use the new `stateExtensions` and `handleRefresh` exports.

 `monaco-json` and `monaco-yaml` both provide json schema features for json, cson and yaml, and we want the nascent codemirror 6 to have them as well!
 
 Also, json5 is slowly growing in usage, and it needs full language support for the browser!

-## Our Goals
-
-- working GeoJSON spec linter & completion
-- working variables json mode for `cm6-graphql`, ala `monaco-graphql`
-- json5 support for `graphiql` as a plugin!
-- perhaps use @lezer to make a json5 language service for monaco-editor + json5?
-- json5 + json4 json schema features for all!
