Default ext-x-version in AWS generated manifest files

Question

Is the default value of _#EXT-X-VERSION_ tag in a manifest file currently 5 and do you have any plans to increase it? If so then do you have any roadmap or schedule for that?  
Do you have any recommendations about how to limit the maximum _#EXT-X-VERSION_ number in manifest file in case the player device doesn't support some newer features?  
Or is there a possibility to specify a maximum _#EXT-X-VERSION_ value in generated manifest files?

Answer

There is no default value of EXT-X-VERSION. MediaPackage configure EXT-X-VERSION base on the feature being used. If it is an encrypted endpoint, it will have a higher EXT-X-VERSION. If it is a clear endpoint, it will have a lower EXT-X-VERSION.   
  
The default behaviour of MediaPackage is to use an EXT-X-VERSION as low as possible for the feature-set selected. This is not configurable.

Answer

To elaborate a little on what Sam said, here's a link to the relevant part of the HLS spec:  
https://developer.apple.com/documentation/http_live_streaming/about_the_ext-x-version_tag  
  
In summary, the usage of certain features will determine this value, if you must see a higher value, you'll need to include the features/parameters detailed in the above spec
