Modified Aid, cleric's ring, to give 25 HP instead of 5. Modified treasure table to add the rings to the custom vendor from Mudd's Curios mod (if installed).
As advised, all rings are now inside a bag, instead of being sold or looted individually. So now you buy the bag of rings or loot the bag of rings from the tutorial chest. Nothing else new. Existing saves should be fine with updating to the new version.
Removed the upper limit on the ability modifiers on all rings. Now, instead of "+2 up to 24" it should just be "+2" bonus to charisma or dexterity, etc.
