After updating omniosce from r101524 to r101526 and napp-it from 18.01 feb 02/2018 to 18/01 arp 02/2018 I am getting the below, should I upgrade both my pools? rpool and my NAS pool? which version will this become after the upgrade? I beleive I am on version 5000 currently.

zpool status
pool: NASS
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.
scan: resilvered 11.5K in 0h0m with 0 errors on Sun May 13 14:21:01 2018

Thank you.
 
There are new incompatible but very nice features like systemwide checkpoints and vdev remove
that are available after a pool update (version remains 5000 but with new features).

If you update and use the new features this pool will be incompatible/not importable on a former OmniOS/OI or other Open-ZFS
 
Thank you _Gea for all your help, I am currently running r101526 is it better to go to the lts version r101522 until support for this expires or should I just continue upgrading to the new stable versions?
 
If you need a release that remains the same for years but with critical fixes, use LTS.
If you like newer ZFS features, use latest stable.
