 ## Ajv v7 beta is released
 
-[Ajv version 7.0.0-beta.1](https://github.com/ajv-validator/ajv/tree/v7-beta) is released with these changes:
+[Ajv version 7.0.0-beta.3](https://github.com/ajv-validator/ajv/tree/v7-beta) is released with these changes:
 
+- added support of the new keywords from [draft 2019-09](https://json-schema.org/draft/2019-09/release-notes.html) of JSON-Schema specification: `unevaluatedProperties` and `unevaluatedItems`, `dependentRequired` and `dependentSchemas`, `maxContains` and `minContains`.
 - to reduce the mistakes in JSON schemas and unexpected validation results, [strict mode](./docs/strict-mode.md) is added - it prohibits ignored or ambiguous JSON Schema elements.
 - to make code injection from untrusted schemas impossible, [code generation](./docs/codegen.md) is fully re-written to be safe and to allow code optimization (compiled schema code size is reduced by more than 10%).
-- to simplify Ajv extensions, the new keyword API that is used by pre-defined keywords is available to user-defined keywords - it is much easier to define any keywords now, especially with subschemas.

[ajv-keywords](https://github.com/ajv-validator/ajv-keywords) package was updated to use the new API (in [v4.0.0-beta.0](https://github.com/ajv-validator/ajv-keywords/releases/tag/v4.0.0-beta.0))
 - schemas are compiled to ES6 code (ES5 code generation is supported with an option).
 - to improve reliability and maintainability the code is migrated to TypeScript.
