+==== Autowiring Primary beans
+
+Camel will now take into account `@Primary` beans from Spring when autowiring
by type.
+For example a JDBC `DataSource` in the SQL component will now use the
`@Primary` data source
+when multiple data sources are defined.
+
+Previously Camel would not autowire if there are 2 or more beans for a given
type.
+
+NOTE: This is a change in behaviour, that can affect your applications when
upgrading.
+
+==== Properties
The `initialProperties` and `overrideProperties` on Camel
`PropertiesComponent` will now
take precedence over Spring Boot properties. This can be used for testing
purpose,
to allow overriding properties when using `CamelTestSupport` for unit testing.
