+1.51 (08-12-2020)
+
+New features:
+   * New option "frenchpart" for French (#458).
+   * New option "splithyphens" for Croatian (#454).
+
+Bug fixes:
+
+   * Use new LaTeX core hooks rather than filehook package. This fixes
+     a recent breakage of filehook with other external packages (#453).
+   * 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).
+   * Allow for hyphenations in words following opening guillemet in French
+     with XeTeX (#462).
