Update 3.7 to 3.11
-----------------------
Changes in 3.11
* If a yahrzeit would fall on 30 Cheshvan in a short year, advance
  observance to 1 Kislev. If a yahrzeit would fall on Kislev 30 in a
  short year, advance observance to 1 Tevet.
* Allow Ta'anit Bechorot (Fast of the Firstborn) to fall on a
  Friday. When a fast day falls on Friday, we do in fact observe the
  fast on Friday, even though Shabbat follows immediately. Also, in some
  years, Asarah Betevet (Tenth of Tevet) falls on Friday and is observed
  on that day.
  It is only in years when the date of the fast falls on Shabbat that
  the fast is moved: Ta'anit Ester (Fast of Esther) and Ta'anit Bekhorim
  are moved back to Thursday. Tsom Gedalyah (Fast of Gedaliah) and
  Shiv'ah Asar Betammuz (Seventeeth of Tammuz) are moved ahead to
  Sunday. Tish'ah Be'av (Ninth of Av), a full-day fast, is moved ahead
  to Saturday night. Asarah Betevet does not fall on Shabbat.
