0.51    2024-10-21
        [CHANGES]
         * Permit convergent futures to not cancel some component futures,
           simplifying the use of `->without_cancel`
         * Give a more obvious error message when a `Test::Future::Deferred`
           runs out of things to do
         * Various small module style updates to documentation, unit tests,
           etc
         * Now requires Perl version 5.14 or later
