 ## Feature Flags
 
 - `derive` (enabled by default) - provides `#[derive(JsonSchema)]` macro
-- `impl_json_schema` - implements `JsonSchema` for Schemars types themselves
-- `preserve_order` - keep the order of struct fields in `Schema` and `SchemaObject`
+- `preserve_order` - keep the order of struct fields in `Schema` properties
 - `raw_value` - implements `JsonSchema` for `serde_json::value::RawValue` (enables the serde_json `raw_value` feature)
 
 Schemars can implement `JsonSchema` on types from several popular crates, enabled via feature flags (dependency versions are shown in brackets):

-- `indexmap1` - [indexmap](https://crates.io/crates/indexmap) (^1.2)

-- `either` - [either](https://crates.io/crates/either) (^1.3)
-- `uuid08` - [uuid](https://crates.io/crates/uuid) (^0.8)
-- `uuid1` - [uuid](https://crates.io/crates/uuid) (^1.0)

 For example, to implement `JsonSchema` on types from `chrono`, enable it as a feature in the `schemars` dependency in your `Cargo.toml` like so:
 
 ```toml
 [dependencies]
-schemars = { version = "0.8", features = ["chrono"] }
+schemars = { version = "1.0.0-alpha.1", features = ["chrono04"] }
 ```
