I might be a bit early with my feedback, because i've only played a few hours on the new version so far. My first impressions:
+ weapon racks!
+ small siege tower
+ forward base (love the idea!)
- forward base not working yet
+ new catapult vs walls damage system
- walls not getting damaged by catapults yet
+ collision more realistic (no silly swiping through floor and walls with huge weapons, this nerf was needed!)
+ riding requirements increased
+ rider self bump removed
+ horse riding top speed bonus decreased slightly
~ horse acceleration decreased slightly
~ horse turning speed decreased slightly
(i'm probably biased)
+ new items
+ minor item price rebalances
+ much needed throwing buff
+ archery damage by arrow type
+ massive amount of irrational whine like always
+ placebo hitboxes 'nerf '
edit:
- desert horse requires riding 6? bit too much.
