A full list of changes delivered in the 2.0 release can be found at MicroProfile OpenAPI 2.0 Milestone.

1. Incompatible Changes

• Model interfaces that were deprecated in 1.1 have been removed:

  • Scopes - this interface was replaced with Map<String, ServerVariable> because it did not need to be extensible (328)

    • variables(ServerVariables variables) - use variables(Map) instead (245)

2. API/SPI Changes

• The @SchemaProperty annotation has been added to allow the properties for a schema to be defined inline. (360). For example:

@Schema(properties={
@SchemaProperty(name="creditCard", required=true),
@SchemaProperty(name="departureFlight", description="The departure flight information."),
@SchemaProperty(name="returningFlight")
})

• The @RequestBodySchema annotation has been added to provide a shorthand mechanism to specify the schema for a request body (363). For example:

@RequestBodySchema(MyRequestObject.class)

• The @APIResponseSchema annotation has been added to provide a shorthand mechanism to specify the schema for a response body (363). For example:

@APIResponseSchema(MyResponseObject.class)

• The mp.openapi.schema.* MicroProfile Config property has been added to allow the schema for a specific class to be specified. This property would typically be used in cases where the application developer does not have access to the source code of a class (364). For example:

mp.openapi.schema.java.time.Instant = { \
"name": "EpochSeconds", \
"type": "number", \
"format": "int64", \
"title": "Epoch Seconds", \
"description": "Number of seconds from the epoch of 1970-01-01T00:00:00Z" \
}

3. Functional Changes

• Getter methods on model interfaces that return a list or map now return a copy of the list/map containing the same items. This list/map CAN be immutable. (240)

• Setter methods on model interfaces that take a list or a map as a parameter MUST not use the list/map instance directly (284)

4. Other Changes

• JavaDoc updates to clarify the behaviour of getter methods on model interfaces that return a list or map ((240), 288)

• TCK updates updates to verify that getter methods on model interfaces return a list or map, return a copy of underlying collection ((240), 288)
