v0.19

    * FEATURE:  `hrpg tasks` and `hrpg [daily|todo|habit]` now support
                an optional search parameter.

    * FEATURE:  Experimental tag support. Add a [tags] section to your
                ~/.habitrpgrc file with tag => uuid pairs. All searches
                starting with a '^' will match all tasks with that
                tag.  (Eg: `hrpg daily ^home`)

    * FEATURE:  Experimental tag prefix support. Add a [config]
                section to your ~/.habitrpg file and a
                `tag_prefix = whatever` section if you don't like the
                default tag character of '^'.
