Spotlight serach is broken for me, was it mentioned in the release notes? Otherwise it’s mostly fine, aside from some layout issues related to new features
Same applies for my Series 8 45mm watch. Briefly warm and took a few days to index whatever needed indexing. During this time the battery depleted at a much faster rate. Typically by 4pm it has about 69%. During the two “indexing” days I saw 10% and 13%. It now has what I consider normal battery usage with no changes in behavior by me.
