## Library Updates

### [big-brain]

[big-brain] ([GitHub][big-brain-github], [Discord][big-brain-discord]) by [@zkat]
is a highly-parallel [Utility AI][big-brain-utility-ai] library
for the Bevy game engine.

[big-brain] recently tagged [v0.16.0][big-brain-v16],
bringing with it a couple of breaking changes and a few goodies.

Probably the biggest change in this release is removal of the blanket
[`ActionBuilder`][big-brain-action-builder] and [`ScorerBuilder`][big-brain-scorer-builder]
implementations for `Clone` types. This is a fairly significant breaking change,
but one that is fairly easy to resolve: simply use the new `#[derive(ActionBuilder)]`
and `#[derive(ScorerBuilder)]` macros to derive the necessary implementations
for your Action and Scorer Components and you should be good to go.

Finally, since the recent [merging of the bevy scheduler changes][big-brain-bevy-scheduler-changes],
big-brain users should expect the next version of big-brain to bring with it
some significant breaking changes to scheduling, so keep an eye out for that
and be mindful of building a lot on top of the current [`BigBrainStage`][big-brain-stage]
(which is used by the default `BigBrainPlugin`).
