+New features:
+   * New option "frenchpart" for French (#458).
+   * New option "splithyphens" for Croatian (#454).
+
+Bug fixes:
+

+   * Remove very old code that pretends polyglossia is babel (#455).
+   * Fix spelling of Albanian contentsname (#456).
+   * Fix part heading modification in French (#458).
+   * Fix extra space in Hebrew (#459).
+   * Register main polyglossia language earlier (#461).
