flippant v0.4.0 Release Notes

Release Date: 2017-10-20 // over 6 years ago

  • ✨ Enhancements

    • [Flippant] - Add a new Postgres adatper, backed by Postgrex.
    • [Flippant] - Add exists?/1 for checking whether a feature exists at all, and exists?/2 for checking whether a feature exists for a particular group.
    • [Flippant] - Add rename/2 for renaming existing features.
    • 🔀 [Flippant] - Merge additional values when enabling features. This prevents clobbering existing values in "last write wins" situations.
    • 👍 [Flippant] - Support enabling or disabling of individual values. This makes it possible to remove a single value from a group's rules.
    • [Flippant] - Add setup/0 to facilitate adapter setup (i.e. Postgres).
    • 🔧 [Flippant.Adapters.Redis] - Accept options to configure the adapter's set key.

    🔄 Changes

    • [Flippant.Adapter] - Values are no longer guaranteed to be sorted. Some adapters guarantee sorting, but race conditions prevent it in the Postgres adapter, so it is no longer guaranteed.
    • [Flippant.Registry] - Use a named ETS table for rule storage rather than an Agent. This is slightly faster, and it prepares us for crash recovery.

    🐛 Bug Fixes

    • [Flippant] - Correct guard logic for multiple when clauses.
