• Updated zoneinfo to 2016b
• Changed MANIFEST.in to explicitly include test suite in source distributions,
  with help from @koobs (gh issue #193, pr #194, #201, #221)
• Explicitly set all line-endings to LF, except for the NEWS file, on a
  per-repository basis (gh pr #218)

  #104, pr #207)
• Changed to an explicit error when rrulestr strings contain a missing BYDAY
  (gh issue #162, pr #211)
• tzfile now correctly handles files containing leapcnt (although the leapcnt
  information is not actually used). Contributed by @hjoukl (gh issue #146, pr

• Adjusted documentation to reflect possibly counter-intuitive properties of
  RFC-5545-compliant rrules, and other documentation improvements in the rrule
  module (gh issue #105, gh issue #149 - pointer to the solution by @phep,
  pr #213).
