 ### Added:
 - Support generic default values in `default` attributes (https://github.com/GREsau/schemars/pull/83)
 - Add missing MIT licence text for usage of code from regex_syntax crate (https://github.com/GREsau/schemars/pull/132)
+- Support uuid v1 and arrayvec 0.7 via feature flags `uuid1` and `arrayvec07` (https://github.com/GREsau/schemars/pull/142)
+    - This also adds `uuid08` and `arrayvec05` feature flags for the previously supported versions of these crates. The existing `uuid` and `arrayvec` flags are still supported for backward-compatibility, but they are **deprecated**.
+    - Similarly, `indexmap1` feature flag is added, and `indexmap` flag is **deprecated**.

 # Feature Flags and Optional Dependencies
-
-Some functionality can be selectively enabled/disabled via [Cargo features](https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section). These can be enabled when you add Schemars to your crate's cargo.toml, e.g.
-```toml
-[dependencies]
-schemars = { version = "0.6", features = ["chrono"] }
-```
-
-## 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`
