How to find out if new samples are available

SO I have gone through last month and created my own soundsets using a lot of the samples in other soundsets. I assume there are new sound samples always being added to the libraries, but how would I know that?

Is there a place that this information is made available?
ie. Jun2 29, 2019 New samples added:
Horse gallop
Horse trot

This was I know to go and check them out and use them in my soundsets if desired?

Thanks! Dpilsner
