v0.8.1

Added:

• SchemaGenerator::definitions_mut() which returns a mutable reference to the generator's schema definitions
• Implement JsonSchema for slices

Changed:

• Minimum supported rust version is now 1.37.0
• Deriving JsonSchema on enums now sets additionalProperties to false on generated schemas wherever serde doesn't accept unknown properties. This includes non-unit variants of externally tagged enums, and struct-style variants of all enums that have the deny_unknown_fields attribute.
• Schemas for HashSet and BTreeSet now have uniqueItems set to true (#64)

Fixed

• Fix use of #[serde(transparent)] in combination with #[schemars(with = ...)] (#67)
• Fix clippy field_reassign_with_default warning in schemars_derive generated code in rust <1.51 (#65)
• Prevent stack overflow when using inline_subschemas with recursive types
