Changed:
   * Increase size of 'xref' column in collections' tables due to some larger sizes reported.

    guzzlehttp/promises) still use it however.


0.8.6.0 2018-05-07
Added:
   * tpg' option (to './zed verify tables' sub-command), which checks for missing tables of active
    groups and creates them. It does not delete tables of inactive groups.

Fixed:
   * Issue where the date after 'release have been disabled/terminated by Releases' was printed as
    the format string instead of the formatted numbers.

Fixed:
   * Actually merge in the PHPMailer fix.


0.8.5.1 2018-04-05
