### Added

- Support for `#elif` preprocessor directive. [#3268](https://github.com/fsprojects/fantomas/issues/3268)

### Fixed

- Multiline `val` body in signature files was not indented correctly. [#3269](https://github.com/fsprojects/fantomas/pull/3269)
- `///` doc comment without associated declaration (e.g. at end of file) was duplicated when formatting. [#2499](https://github.com/fsprojects/fantomas/issues/2499)
- NamedIndexedPropertySet with two SynLongIdent removed space. [#3273](https://github.com/fsprojects/fantomas/issues/3273)
- `%%` (double-percent) infix operator moved to new line, producing invalid F#. [#2107](https://github.com/fsprojects/fantomas/issues/2107)
- Indentation warning when formatting `match` with long anonymous record discriminant. [#1903](https://github.com/fsprojects/fantomas/issues/1903)
- Index-without-dot with variable key followed by unit arguments added spurious spaces, e.g. `dict[key] () ()` became `dict [ key ] () ()`. [#2519](https://github.com/fsprojects/fantomas/issues/2519)
- Open-ended expressions (lambda, if-then-else, match, ...) in non-last positions of infix, tuple, list/array, and record expressions now stay multiline to preserve semantics. [#3279](https://github.com/fsprojects/fantomas/issues/3279)
- Lambda in tuple in list on single line changes code meaning. [#3278](https://github.com/fsprojects/fantomas/issues/3278)
- Custom operator applied to lambda collapses to single line changing semantics. [#3274](https://github.com/fsprojects/fantomas/issues/3274)
