But do they have a haploid- or diploid-dominant lifecycle? Frankly, how do they reproduce at all? Speculative xenobiology for robots that transform into cars is definitely something *I* want to think about.

33. github.com/bevyengin... A simple request to experiment with type magic to avoid ergonomics regressions for state-scoped entities. Easy to test, leaving it in and I'll get to it this week.

Investigate ergonomic improvements for state scoped events API · Issue #19452 · bevyengine/bevy · GitHub

I have reverted back to clear_events_on_exit_state, but unlike with 4 it requires specifying the event type each time. Quick question: if you use an impl Trait argument, rather than a generic, can we get type inference working properly f...

20. github.com/bevyengin... Documentation request for explaining what units we're using in our PBR implementation of emissivity. Unfortunately the glTF spec is unhelpful. This is related to the bevy_solari (global illumination) work, and should be easy to fix. Leaving it.

4. github.com/bevyengin... Shadows aren't affected by render layers. What a nasty bug. It's old though, so not critical. But oh hey, we have a PR to fix this from April. I poked the author about this but they haven't responded yet. Might need to be adopted, but I want to keep this.

23. github.com/bevyengin... I love rendering: they just casually cite and reimplement research papers in production code bases. This looks like a performance improvement for ReSTIR, a ray-traced lighting technique that bevy_solari implements. Clean, faster and well-reviewed, merging.

1. github.com/bevyengin... Onto more serious matters, we're apparently starting with a major rendering feature? Okay, sure! A realtime, Bevy-based tool to create environment maps sure seems useful: I've seen a ton of complaints about fragile setups for the existing tooling.

14. github.com/bevyengin... Why is it always edge cases? Rendering features are so tricky to ship because of the complex interaction between features. Good work detecting this bug, and good job fixing it. We could use more rendering tests to test all these combinations, but merging the fix now.

7. github.com/bevyengin... A simple enough bug fix for resizing images while on the GPU, a functionality that we introduced earlier this cycle. To fix it, we need to pass in the old asset, which apparently is broadly useful. Neat! Happy to merge this, especially since then we never ship the bug.

3. github.com/bevyengin... Networking folks are up to their nonsense again: they really push Bevy's ability to operate generically to its limit. This time, we're taking a look at how to improve ergonomics for entity mapping, used to reconstruct webs of entities across a serialization boundary.

Unfortunately, changing your coordinate system is *miserable*, and there's no Objectively Correct argument for what coordinate system should be used. Aligning with glTF is a good choice for Bevy, but suddenly breaking everyone's projects in the version upgrade is not.

In this case, a user was confused about why they could use `&query` in a for loop, but not `&populated`. Turns out, this inconsistency is just an overlooked trait implementation :) Wait a few days, and bam: first-time contributor scratching their own itch. Welcome! Merging :)

Good: I really appreciate this design. Components are Bevy's natural unit of composition and opt-in behavior, and the ability for other effects stored as components to require this Hdr component is perfect. Faster filtering is a nice bonus, even if for small n it doesn't matter. Merging :)

29. github.com/bevyengin... Hey, this one was reviewed in the middle of my merge train! I review them in chronological order to help unblock folks whose work has been languishing in the event of merge conflicts. Looks like a nice rendering cleanup: moving the HDR camera field into a component.

to be fair the all options for gtk have their own annoying tradeoffs, but people also use them for other things (and they weren't proudly inspired by "the ergonomics of Java and C#")

11. github.com/bevyengin... Another Charlotte rendering bug fix: falling back to `GpuPreProcessingMode::None` if the device doesn't have the required features. Sure, very reasonable. Oh hey, Rob already beat me to merging this one! Excuse me, this is *content*!

I'd thought svelte didn't process signals until they are read in the ui. or would they still technically be "on screen" with stack navigation?

Starts off a little dicey: "crash" + "after a long period of time" is never a fun combination. And all we have to go off of is a crash due to a null UUID being created?? This hasn't been widely reported, so I *bet* it's machine-specific in some way. Drivers, hardware, OS... so much to go wrong!
