- Jackson 2.6 went GA in July 2015, almost a year ago by the time of our 4.3 GA release. Let's get rid of the reflective checks and deprecated method calls in MappingJackson2MessageConverter and AbstractJackson2HttpMessageConverter.
- FreeMarker 2.3.21 was released in October 2014, as a rather major update. Let's get rid of the deprecated method calls in FreeMarkerConfigurationFactory and FreeMarkerView.
- XStream 1.4.5 was released in September 2013. Let's finally require it and get rid of the deprecated constructor call in XStreamMarshaller.
