    🚀 This section describes the changes in the 2.0.0 release. A detailed list of
    🔄 changes can be found here: https://huey.readthedocs.io/en/latest/changes.html

    Overview of changes:

    • always_eager mode has been renamed to immediate mode. Unlike previous
      🔖 versions, immediate mode involves the same code paths used by the consumer
      ✅ process. This makes it easier to test features like task revocation and task
      ⏱ scheduling without needing to run a dedicated consumer process. Immediate
      🔧 mode uses an in-memory storage layer by default, but can be configured to use
      "live" storage like Redis or Sqlite.
    • 🚚 The events stream API has been removed in favor of simpler callback-driven
      🚦 signals APIs. These
      🔀 callbacks are executed synchronously within the huey consumer process.
    • A new serialization format is used in 2.0.0, however consumers running 2.0
      will continue to be able to read and deserialize messages enqueued by Huey
      🔖 version 1.11.0 for backwards compatibility.
    • 👌 Support for task priorities.
    • 🆕 New Serializer abstraction allows users to customize the serialization
      format used when reading and writing tasks.
    • ⏱ Huey consumer and scheduler can be more easily run within the application
      🖨 process, if you prefer not to run a separate consumer process.
    • Tasks can now specify an on_error handler, in addition to the
      👍 previously-supported on_complete handler.
    • Task pipelines return a special ResultGroup object which simplifies reading
      the results of a sequence of task executions.
    • SqliteHuey has been promoted out of contrib, onto an equal footing with
      🚀 RedisHuey. To simplify deployment, the dependency on
      🚚 peewee was removed and the Sqlite
      storage engine uses the Python sqlite3 driver directly.
