AXYS RMK, What's the difference between model years 16 to 17 and 17 to 18?

If there's a thread on here already going through this topic please point me in the direction as I tried a few searches and came up empty. Thanks.

if not...

What changes/improvements did Polaris make to the AXYS in 2017 over the 2016s and then what changes were made for model year 2018 over 2017?

Most interested in the Pro-
RMK platform in 155/163 Series 6.0 (Not SKS, Snowcheck, or Series 7.0)

Those new 2018 updates include:
800 H.O. Cleanfire Engine Update
New thermostat provides:
- Lower operating temperature, 110 degrees F (43.3º C) vs. 125 degrees F (51.6º C) for improved overheat margin and more consistent engine operation.
- Increases main circuit flow by 12 percent; increases bypass flow 9 percent.
- New thermostat will come on all 2018 snowmobiles with the 800 H.O. Cleanfire engine.
More durable exhaust gas temp sensor (EGT) providing more than 200 percent life improvement:
- Improved connector
- More durable sensing element
- Matched to new ECU
Sealed cross-shaft cavity crankcases provide additional lubrication and increased durability on both 600 and 800 H.O. Cleanfire engines.
Improved MAG end seal provides better sealing and increased durability on both 600 and 800 H.O.
RMK Monotube Shock Updates
MY18 RMK Monotube Shocks will feature all new valving with “Hi Flow” Walker Evans pistons on the front suspension and rear track shock that delivers less bottoming in the big bumps while maintaining a supple feel on the trail.
