 # Changelog
 
-## [0.8.4] - **In-dev**
+## [0.8.8] - 2021-11-25
+### Added:
+- Implement `JsonSchema` for types from `rust_decimal` and `bigdecimal` crates (https://github.com/GREsau/schemars/pull/101)
+
+### Fixed:
+- Fixes for internally tagged enums and flattening additional_properties (https://github.com/GREsau/schemars/pull/113)
+
+## [0.8.7] - 2021-11-14
+### Added:
+- Implement `JsonSchema` for `EnumSet` (https://github.com/GREsau/schemars/pull/92)
+
+### Fixed:
+- Do not cause compile error when using a default value that doesn't implement `Serialize` (https://github.com/GREsau/schemars/issues/115)
+
+## [0.8.6] - 2021-09-26
+### Changed:
+- Use `oneOf` instead of `anyOf` for enums when possible (https://github.com/GREsau/schemars/issues/108)
+
+## [0.8.5] - 2021-09-20
+### Fixed:
+- Allow fields with plain `#[validate]` attributes (https://github.com/GREsau/schemars/issues/109)
+
+## [0.8.4] - 2021-09-19
 ### Added:
 - `#[schemars(schema_with = "...")]` attribute can now be set on enum variants.
+- Deriving JsonSchema will now take into account `#[validate(...)]` attributes, compatible with the [validator](https://github.com/Keats/validator) crate (https://github.com/GREsau/schemars/pull/78)
 
 ## [0.8.3] - 2021-04-05

+`#[validate(phone)]` / `#[schemars(phone)]`<br />

+
+Sets the schema's `format` to `email`/`phone`/`uri`, as appropriate. Only one of these attributes may be present on a single field.

+Sets the `minLength`/`maxLength` properties for string schemas, or the `minItems`/`maxItems` properties for array schemas.

+<h3 id="range">

+
+`#[validate(regex = "path::to::regex")]` / `#[schemars(regex = "path::to::regex")]`
+`#[schemars(regex(pattern = r"^\d+$"))]`
+</h3>
+
+Sets the `pattern` property for string schemas. The `path::to::regex` will typically refer to a [`Regex`](https://docs.rs/regex/*/regex/struct.Regex.html) instance, but Schemars allows it to be any value with a `to_string()` method.
+
+Providing an inline regex pattern using `regex(pattern = ...)` is a Schemars extension, and not currently supported by the Validator crate. When using this form, you may want to use a `r"raw string literal"` so that `\\` characters in the regex pattern are not interpreted as escape sequences in the string.

+Validator docs: [regex](https://github.com/Keats/validator#regex)
+
+<h3 id="contains">
+
+`#[validate(contains = "string")]` / `#[schemars(contains = "string")]`
+</h3>
+
+For string schemas, sets the `pattern` property to the given value, with any regex special characters escaped. For object schemas (e.g. when the attribute is set on a HashMap field), includes the value in the `required` property, indicating that the map must contain it as a key.

+
+<h3 id="required">
+
+`#[validate(required)]` / `#[schemars(required)]`<br />
