+## 7.1.1 (2020-03-01)
+
+### Bug fixes
+
+Treat `\8` and `\9` as invalid escapes in template strings.
+
+Allow unicode escapes in property names that are keywords.
+
+Don't error on an exponential operator expression as argument to `await`.
+
+More carefully check for valid UTF16 surrogate pairs in regexp validator.
+
+## 7.1.0 (2019-09-24)
+
+### Bug fixes
+
+Disallow trailing object literal commas when ecmaVersion is less than 5.
+
+### New features
+
+Add a static `acorn` property to the `Parser` class that contains the entire module interface, to allow plugins to access the instance of the library that they are acting on.
+
+## 7.0.0 (2019-08-13)
+
+### Breaking changes
+
+Changes the node format for dynamic imports to use the `ImportExpression` node type, as defined in [ESTree](https://github.com/estree/estree/blob/master/es2020.md#importexpression).
+
+Makes 10 (ES2019) the default value for the `ecmaVersion` option.
+
+## 6.3.0 (2019-08-12)
+
+### New features
+
+`sourceType: "module"` can now be used even when `ecmaVersion` is less than 6, to parse module-style code that otherwise conforms to an older standard.
+
+## 6.2.1 (2019-07-21)
+
+### Bug fixes
+
+Fix bug causing Acorn to treat some characters as identifier characters that shouldn't be treated as such.
+
+Fix issue where setting the `allowReserved` option to `"never"` allowed reserved words in some circumstances.
