Supported RAW formats for new cameras after the development stopped?
Our trusted list of RAW formats supported by Aperture has not been updated for quite some time: http://www.apple.com/aperture/specs/raw.html
None of the cameras listed in the Digital Camera RAW Compatibility Update 6.17 for El Capitan are on Aperture's compatibility list.
I am happy to say, that the RAW format of my new Panasonic LUMIX DMC-FZ300 is working well in Aperture 3.6 on MacOS X 10.11.3 El Capitan nevertheless.
I would like to hear, if other cameras from the most recent Digital Camera RAW Compatibility updates are also working well in Aperture 3.6, in spite of being not listed in Aperture's list, but are working as part of El Capitan: Digital camera RAW formats supported by OS X El Capitan - Apple Support
