3.5.0 Breaking Changes

Vert.x Auth

• JWTAuth create method now takes JWTAuthOptions instead of JsonObject for configuration. This brings more type safety to the config and less undocumented features of the provider. https://github.com/vert-x3/vertx-auth/pull/124
• Oauth2Auth the method getToken is now deprecated and replaced by the common authenticate https://github.com/vert-x3/vertx-auth/pull/156
• OAuth2Auth the method api is removed as it was supposed to be an internal helper to get a Token and is not suitable for usage outside that. A new Api fetch is added to the AccessToken for general use.

Hazelcast Cluster Manager

• Hazelcast has been upgraded to 3.8.2. All nodes in the cluster should use Hazelcast 3.7+. See the Hazelcast Compatibility Matrix

MQTT Server

• The publishCompleteHandler in the MqttEndpoint interface is now renamed in publishCompletionHandler to be aligned with handler naming convention in all others Vert.x components.

Vert.x Web

• io.vertx.ext.web.handler.sockjs.BridgeEventType enum has been removed and you should use: io.vertx.ext.bridge.BridgeEventType enum instead.
• SessionStore put, clear, delete take in AsyncResult<Void> instead of AsyncResult<Boolean> as the value was always true and did not reflect if the operation succeeded.

Consul client

• In case the key is not found, the methods ConsulClient#getValue() and ConsulClient#getValueWithOptions() provides an empty KeyValue object instead of an failed AsyncResult
• In case the key prefix is not found, the methods ConsulClient#getValues() and ConsulClient#getValuesWithOptions() provides an empty KeyValueList object instead of an failed AsyncResult
• Watchers must handle WatchResult object instead of AsyncResult

Service Discovery

• In clustered mode the service discovery default backend has been updated to use another strategy. All member needs to be updates to read / write in this new backend.

Vert.x for Ruby

• All predicate methods end with question mark again (lost in 3.4). It is idiomatic in Ruby.

Vert.x for Groovy

• The automatic migration path for Verticles written against the previous API has been removed - Vert.x 3.5.0 assumes that applications have been migrated to the new API.
