[Merged by Bors] - News: Release 0.10.0

[cart]

How This Works

For the Bevy 0.10 release blog post (and for the first time ever), I'm publicly opening the doors to other people writing blog post sections. Specifically, if you worked on a feature in a substantial way and are interested in presenting it, you can now ask to claim a section by leaving a comment in this PR. If you claim a section, submit a pull request to the release-0.10.0 branch in this repo. For the next week, we will be filling in sections (the release target is Saturday March 4th). Please don't claim a section if you don't plan on completing it within that timeline. Also don't claim a section if you weren't an active participant in the design and implementation of the change (unless you are a Maintainer or SME).

I will claim any unclaimed sections.

Try to match the style of previous release blog posts as much as possible.

1. Show, don't tell. Don't bombard people with information. Avoid large walls of text and large walls of code. Prefer the pattern "byte sized description of one thing" -> "example code/picture/video contextualizing that one thing" -> repeat. Take readers on a journey step by simple step.
2. Don't use up reader's "mental bandwidth" without good reason. We can't afford page-long descriptions of minor bug fixes. If it isn't a "headliner change", keep the description short and sweet. If a change is self describing, let it do that (ex: We now support this new mesh shape primitive ... this is what it looks like). If it is a "headliner change", still try to keep it reasonable. We always have a lot to cover.
3. In slight competition with point (2), don't omit interesting technical information when it is truly fun and engaging. A good chunk of our users are highly technical and enjoy learning how the sausage is made. Try to strike a balance between "terse and simple" and "nerdy details".
4. When relevant, briefly describe the problem being solved first, then describe the solution we chose. This contextualizes the change and gives the feature value and purpose.
5. When possible, provide visuals. They create interest / keep people hooked / break up the monotony.
6. Record images and videos at the default bevy resolution (1280x720)
7. Provide an accurate listing of authors that meaningfully contributed to the feature. Try to sort in order of "contribution scale". This is hard to define, but try to be fair. When in doubt, ask other contributors, SMEs, and/or maintainers.
8. Provide numbers and graphs where possible. If something is faster, use numbers to back it up. We don't (yet) have automated graph generation in blog post style, so send data / info to me (@cart) if you want a graph made.

Headliners

Headliners are our "big ticket high importance / high profile" changes. They are listed briefly at the beginning of the blog post, their entries are roughly sorted "to the top", and they are given priority when it comes to "space in the blog post". If you think we missed something (or didn't prioritize something appropriately), let us know.

• ECS Schedule v3 (previously known as "stageless")
• Partial Android Support
• Depth and Normal Prepass
• Environment Map Lighting
• Cascaded Shadow Maps
• Distance and Atmospheric Fog
• Smooth Skeletal Animation Transitions
• Enable Parallel Pipelined Rendering
• Windows as Entities
• Renderer Optimizations
• ECS Optimizations

Sections

These are the sections we will cover in the blog post. If a section has been claimed, it will have (claimed by X) in the title. If it is unclaimed it will have (unclaimed) in the title. Let us know if we missed a section. We don't cover every feature, but we should cover pretty much everything that would be interesting to users. Note that what is interesting or challenging to implement is not necessarily something that is relevant to our blog post readers. And sometimes the reverse is true!

If you believe a section should be split up or reorganized, just bring it up here and we can discuss it.

SMEs (@cart)

This was already covered in another blog post. Just briefly call out what they are and that this is the first release that used them. Link to the other blog post.

• Subject Matter Experts and new Bevy Org docs

[Aceeri]

I'll claim the Windows as Entities portion :)

[alice-i-cecile]

My draft post for schedule v3 is stored here for now.

[alice-i-cecile]

bevyengine/bevy#7359

This one is worth highlighting as an exceptionally nice new example.

[james7132]

I can take the ECS and Rendering Optimizations sections. I wrote a good number of those PRs, though @danchia, @superdump, and @JoJoJet might want to chime in too.

I can also take the Iterate EntityRef and Smooth Animation Transition sections as well. I'd like to mention the intended roadmap for animation composition going forward there.

[BrandonDyer64]

Will there be a section for Temporal Anti-aliasing?

[alice-i-cecile]

If it's reviewed and merged in time for the release I would expect it to be in there.

[JoJoJet]

I think bevyengine/bevy#7306 should be mentioned with Ref queries. I can write that section.

[harudagondi]

I wanna claim the AddAudioSource trait and the spatial audio one :)

[hymm]

I'll write something up for pipelined rendering.

[cart]

@IceSentry has claimed the prepass section

[nicopap]

Any interest in featuring the parallax mapping technic to demonstrate how useful the depth prepass is? Since it's possible to update the depth buffer now, you can do a ton of nifty tricks, like changing occlusion on a pixel level.

I included a screenshot comparing without/with parallax mapping to demonstrate that it's possible to change the depth of things to the point that the original geometry is fully hidden.

[inodentry]

Wow! This blog post has turned out amazing.

It took me a while to read through all of it. I did have some comments, but those issues were addressed in the meantime, before I had finished my review and posted them! So I don't think I have anything major left to say.

A bit late to incorporate at this stage. We should just feature if/when we add that feature to Bevy!
