- Bugfix: negative numbers not validated as integers or numbers in parameters
- Bugfix: Scheme not inferred properly for specs loaded over HTTPS; scheme and host not inferred correctly for relative URL specs (2904)
- Bugfix: Nested readOnly properties are now rendered (2910)
- Improvement: Useless minified component names are hidden when errors occur
- Improvement: Clarified Docker containers to follow Docker best practices. Now `latest` refers to the "latest released version" and `unstable` refers to the current master. We will continue to tag final versions, which is, as always, the safest way to use Docker images.
