### Fixed
- Exception abbreviation loses its right-hand side. [#3511](https://github.com/fsprojects/fantomas/issues/3511)
- Static optimization when T struct loses struct. [#3514](https://github.com/fsprojects/fantomas/issues/3514)
- Static optimization loses the `and` between its conditions, and reverses its conditions and `when` clauses. [#3516](https://github.com/fsprojects/fantomas/pull/3516)
- static extern inside a type loses static. [#3515](https://github.com/fsprojects/fantomas/issues/3515)
