1.15  2019 July 26
        - Fix a bug in the test suite due to floating-point rounding.  Thanks to
          Slaven Rezic (see CPAN RT bug 130150:
                              https://rt.cpan.org/Ticket/Display.html?id=130150)
        - Also improved __DATA__ handling, so as not to hold a lock on the library.

1.14  2019 July 22
        - Fix CPAN RT bug 87484 (https://rt.cpan.org/Ticket/Display.html?id=87484),
          concerning very small floating-point values (e.g. "2.1458e-06").
        - Fix CPAN RT Bug 95447, concerning floating-point numerical time values.
        - Fix CPAN RT Bug 121367, concerning loading perl-only routines after \ 
forking.
          This might (?) also fix bug 74880, but I can't reproduce that.
        - Skip locale tests on openbsd platform.
        - Fix accented strings in locale.t

1.13  2019 July 18
        - Fix CPAN RT bug 85001.
          This was a problem in the test suite only; no code changes were made
          in the main module lib/Time/Format.pm.
          The problem existed in how the test suite checked for whether certain
          CPAN modules were installed, and especially in how it attempted to
          unload them from memory afterward.
          Thanks to Sendu Bala for reporting this -- and to Jim Keenan for
          pushing me to fix this.
