## Library Updates

### [Hanabi]

_Hanabi effect entirely simulated on GPU thanks to the new Expression API of v0.7_

The [Hanabi] library ([GitHub][hanabi-github], [docs.rs][hanabi-docs]) is a
modern VFX library for the [Bevy game engine][bevy]. It focuses on scale to produce
stunning visual effects (VFX) in real time, offloading most of the work to
the GPU (compute shaders), with minimal CPU intervention. The design is inspired
by modern particle systems found in other industry-leading game engines.

This month, [Hanabi] saw its biggest release so far.
Version 0.7 of Hanabi not only brings support for Bevy 0.11,
but also adds a whole new Expression API
to provide a new level of customizing for VFX authors.
With expressions, developers can combine simple building blocks
like simulation parameters (`time`, `delta_time`),
effect properties (user-defined variables controlled from CPU),
and math operators (`add`, `mul`, `cos`, ...),
to directly modify each attribute of a particle (position, velocity, ...)
and form complex behaviors with complete control.
The expression API complements and extends the existing `Modifier`-based workflow
to achieve even more complex effects.

This release also marks a major stepping stone
toward the ability to build a visual editor (node graph)
to build and tweak visual effects in real time.

Other changes include the ability to set a screen-space size for particles,
and a new `KillSphereModifier` to confine particles
to the inside or the outside of a sphere.
See the [CHANGELOG][hanabi-changelog] for all details.
