    • ➕ Added a pre-built tz.UTC object representing UTC (gh pr #497)
    • ➕ Added a cache to tz.gettz so that by default it will return the same object
      for identical inputs. This will change the semantics of certain operations
      between datetimes constructed with tzinfo=tz.gettz(...). (gh pr #628)
    • 🔄 Changed the behavior of tz.tzutc to return a singleton (gh pr #497, #504)

      same inputs. (gh pr #628)

      instance of the relevant tzinfo. (gh pr #628)

      equality with tzoffset and tzutc. (gh pr #598)
    • 🗄 Deprecated the idiosyncratic tzstr format mentioned in several examples but
      evidently designed exclusively for dateutil, and very likely not used by
      any current users. (gh issue #595, gh pr #606)
    • ➕ Added the tz.resolve_imaginary function, which generates a real date from
      an imaginary one, if necessary. Implemented by @Cheukting (gh issue #339,
      gh pr #607)
    • 🛠 Fixed issue where the tz.tzstr constructor would erroneously succeed if
      🔊 passed an invalid value for tzstr. Fixed by @pablogsal (gh issue #259,
      gh pr #581)

      🛠 and fixed by @lapointexavier (gh pr #601)
    • ➕ Added a lock to tz.tzical's cache. Reported and fixed by @Unrud (gh pr #430)

      🛠 fixed by @ryanpetrello (gh issue #614, gh pr #624)

      @jarondl and @mlorant (gh pr #450)
    • Switched to setuptools_scm for version management, automatically calculating
