### Changed
- Update FCS to 'Add range of the when keyword to SynMatchClauseTrivia', commit 409c7a62ea193ec060e87ccad78636feeb0883f1 [#3531](https://github.com/fsprojects/fantomas/pull/3531)
### Fixed
- Comment after 'when' on its own line is lost. The syntax tree had no range for the `when` keyword of a match clause, so a comment after it had no node on its line to attach to. The parser now records that range, and the comment stays after the keyword. [#3521](https://github.com/fsprojects/fantomas/issues/3521)
