0.16    2026-01-28
        [CHANGES]
         * Account for `SVt_PVOBJ` of Perl 5.38+ in the PerlCollector heap
           metrics
         * Use `Future::IO->load_best_impl` of Future::IO 0.18 in the examples

        [BUGFIXES]
         * Use `IO::Socket::IP` rather than `...::INET` to test the Future::IO
           exporter, in case the system provided a 'v6 local address

0.15    2026-01-05
        [CHANGES]
         * Modernise to perl v5.20:
            + Make use of the signatures and postfix deref features
         * Also include the IO counters from /proc/$PID/io in ProcessCollector

0.14    2024-10-25
        [CHANGES]
         * Added `->remove` and `->clear` methods to all metric types
         * Use `meta` module instead of globrefs and `no strict 'refs'`

0.13    2024-07-16
        [CHANGES]
         * Module style updates:
            + use v5.14
            + Swap unit tests from `Test::More` to `Test2::V0`; avoids needing
              `Test::Fatal`

0.12    2022-01-07
        [CHANGES]
         * Added ->export_to_Future_IO

        [CHANGES]
         * Include the Net::Prometheus::PerlCollector module
         * Optionally skip building the XS part of PerlCollector if a C
           compiler is not available

        [BUGFIXES]
         * Fix for Histogram bucket generation for values less than 1 on

        [CHANGES]
         * Pass additional options from query params or ->render method into

              HTTP::Message-based HTTP servers
            + ->export_to_IO_Async method to allow easy export of metrics from
              IO::Async-based applications without an existing HTTP server

0.08    2020-04-28
        [CHANGES]
         * Added Net::Prometheus::Registry
         * Allow Registry to act globally to allow 3rd-party modules to add

        [BUGFIXES]
         * Prometheus needs all the labelsets of every variable grouped
