### Changed
- Bump `FSharp.Core` to `10.0.100`. [#3353](https://github.com/fsprojects/fantomas/pull/3353)
### Fixed
- Chained `?` operator accesses (e.g. `x?a("")?b(t)`) no longer add a space before parenthesised arguments, which previously changed how the next `?member` was parsed. Detected during AST→Oak transformation and represented as a new `Expr.DynamicChain` node so the printer can keep the chain tight; lone `?` calls still respect `SpaceBefore(UpperLower)caseInvocation`.
