Bevy 0.16 is out now!

2025-04-28

Bevy 0.16 is out now!

Checkout out the official release notes, my unofficial Bevy 0.16 video, as well as the 0.15 to 0.16 migration guide.

Expect a slight lull before things pick back up on the Pull Request merge queue for 0.17 and enjoy the new Bevy 0.16 features for a bit :D.

Many ecosystem crates have participated in the release candidate process and thus already have 0.16 compatible versions on crates.io. Some maintainers wait for the stable release so give them some time if they don't have one out yet (much of the ecosystem is volunteer-based, after all) or give them a hand and submit a PR!

There will be a Bevy game jam for 0.16 although official dates have not been announced. If you're trying to plan for the jam, loosely consider the first week of June but wait for the official announcement to make any concrete plans.

remove_if

#18899 introduces a new EntityCommands::remove_if function which can be used in a typical chain of entity commands.

fn remove_combat_stats_system(
    mut commands: Commands,
    player: Res<PlayerEntity>
) {
    commands
        .entity(player.entity)
        .remove_if::<(Defense, CombatBundle)>(|| !player.is_spectator());
}
