Alright #bevy, time to pick up where we left off. It's time for some more riveting #opensource project management! Be warned though: I will be ruthless, nay, downright bloodthirsty as I triage issues and PRs to get us ready for release. Restarting numbering for now

The trivial dependency bump that turned into a disaster due to questionable decisions from getrand on how to handle web support. Sorry! We should make an explicit call on what to do though (even if that's wait for now), so this can stay.

Update `rand`, `glam` and `encase` to latest versions by Bluefinger · Pull Request #18047 · bevyengine/bevy

Objective New rand version, which means updating glam and encase to support the newer ecosystem update. Does mean that this changes how WASM builds need to be done in order to configure getrandom c...

Disabled entities are not working properly with rendering, among other things. This is largely due to our decision to avoid firing change detection and lifecycle events when disabling and re-enabling entities.

A proposed change (again...) to the behavior of `Single`. I'm on the fence about this: it's more consistent but less convenient. We should make the call now and stick with it; this stays in the milestone.

Ah, one of several issues and PRs for "we should finalize the Event trait split before releasing 0.17". These sort of conceptual shifts are often worse for users than more serious breaks, so we need to get this right once and for all.

A Cart issue! We silently lost staticness in our AssetPath types due to a well-intentioned cleanup PR, resulting in unnecessary clones. This needs to be fixed, even if that's just "revert and then add detailed comments explaining why the weird thing was done".

@alice_i_cecile oh no, not again.

Single will become useless again with this change.

I would argue a change in the opposite direction would make a lot more sense.

Have Res systems params behave the same way as Single does now.

Unifying the behavior, and allow users to define to panic through configuration.

If this will be merged, using Query with single and an early out is a lot more ergonomic than `When<Single<&Player>>`.
