### Changed
- Update FCS to 'Record the range of the `of` keyword in SynUnionCaseTrivia', commit 5e9647f158fe282462aba57ed83ada910a91b90e [#3502](https://github.com/fsprojects/fantomas/pull/3502)
### Fixed
- Wrong change of comment's position. The syntax tree had no range for the `of` keyword of a union case or exception, so a block comment after it, as in `exception E of (*name*) string`, was attached to the case name and printed in front of `of`. The parser now records that range, and the comment stays after the keyword. [#1959](https://github.com/fsprojects/fantomas/issues/1959)
- Cursor is lost when placed on `if`, `then` or `else if` keywords. The cursor now keeps its place on `if`, `elif`, `else if`, `then`, `match`, `match!` and `with`. [#3387](https://github.com/fsprojects/fantomas/issues/3387)
- Cursor is lost when placed on the closing bracket of a multiline list or array in the cramped style. [#3506](https://github.com/fsprojects/fantomas/pull/3506)
