Amram Gaon and Maimonides concluded with "who rebuilds Jerusalem," but this appears to have been discarded by all factions. This final blessing is modified for the various festivals and holidays. In all traditions that last phrase, "who sanctifies the Sabbath", is replaced by the appropriate substitute when the occasion is something other than an ordinary Sabbath, if a holiday falling on a Sabbath the phrasing is "And for this Sabbath day and for this day of this..." (if not on a Sabbath, then merely "and for this day of ..."); e.g. (for Passover) "Festival of Matzos", (on Shavuous) "Festival of Shavuous", (on Succos) "Festival of Succos, (on Shemini Atzeres or Simhas Torah) "Festival of the Assembly", (on Rosh Hashana) "Day of Remembrance", (on Yom Kippur) "Day of Atonement", - but it appears from Kol Bo (14th century) that Yom Kippur is the only fast day with a name and therefore this final blessing is not recited at all on other fast days, such as Gedaliah or Esther or Tisha B'Av, since they have no such names that can be inserted into the blessing - and then the festival version of the blessing concludes:
