 ## Bugfixes
 - Fix `BAT_CONFIG_DIR` pointing at system config directory causing duplicate flag errors. Closes #3589, see #3620 (@Xavrir)
+- Fix syntax highlighting for symlinked files when the symlink name has no extension but the target does. Closes #1001, see #3621 (@Xavrir)
 - Report error when pager is missing instead of silently falling back, see #3588 (@IMaloney)
 - Fix `--wrap=never` and `-S` flags being ignored when piping to pager, see #3592 (@IMaloney)
 - Fix crash with BusyBox `less` on Windows, see #3527 (@Anchal-T)
