 ## [Unreleased]
+### Changes
+- `Formatter` no longer recomputes line-ending normalization (`LineEnding.toUnix`) a second time for every formatter step that changes content, removing redundant O(n) work from the core formatting loop. ([#2934](https://github.com/diffplug/spotless/pull/2934))
 
 ## [4.6.1] - 2026-05-15
