0.107     2018-07-24 15:10:36-04:00 America/New_York (TRIAL RELEASE)

    [Fixes]

0.106     2018-07-14 09:37:00-04:00 America/New_York

    [Tests]

    - Protected t/locking.t from PERL_PATH_TINY_NO_FLOCK already
      in the environment.

0.105     2018-07-07 10:09:04-04:00 America/New_York (TRIAL RELEASE)

    [Additions]

    - The PERL_PATH_TINY_NO_FLOCK environment variable has been added to
      allow users to disable file locking (and any associated warnings).

    [Changes]

    - Detection of unsupported 'flock' is no longer BSD-specific.  This
      allows detecting and warning, for example, with the Luster filesystem
      on Linux.

    [Tests]

    - Improve reliability and diagnostics of tests run via 'do'.
