0.13 announcement post

[alice-i-cecile]

Since @cart is drowning in admin paperwork for the legal org already (thanks!), I'm going to lead the effort here this cycle.

Like in #754, I'll stub out the major sections here, and then folks can tackle and refine them in their own PRs to this branch :)

TODOs will be tracked in the post, with the handy TODO marker.

[nicopap]

Please refer to #754 for guideline on how to write your section!

Following is a list of potential sections for the news post. I browsed the commits since November 4th.

If you think other sections should be included, please say it. This list is not exhaustive.

Between parenthesis potential section authors. ?@author means "I think you could write the section", but doesn't mean it is claimed. I've put myself where I'd be glad to claim the section.

[hymm]

I can take "auto sync points".

I think the list above is missing the texture atlas rework from alice's discord list.

[ManevilleF]

I can take the texture atlas rework and texture slicing

[wainwrightmark]

Happy to write up the Split WorldQuery section.

[pcwalton]

I can write the lightmaps and reflection probes sections.

[alice-i-cecile]

Awesome. I'm going to fill out some stub sections momentarily, then please make PRs to this branch :)

[bardt]

I can write Camera-driven UI section

[Jondolf]

I and @NiseVoid can take the primitive shapes; I'll probably write up the beginning, explaining what they are and how they are useful, @NiseVoid will make something on bounding volumes and intersection tests, and I'll make a quick section for primitive meshing. We can also put the new direction and ray types somewhere in there

[Bluefinger]

I could write up about the Entity optimisations, since a fair bit of the work was all fairly related/overlapping.

[IceSentry]

I'll do the bind group layout entries

[Trashtalk217]

Since @Nathan-Fenner did the original implementation, I think they should get first dibs on writing the release notes for that. If they're busy or not interested, I could do that section.

[nicopap]

I think the intro blurb should include a mention of the bevy Jam 4 and its result.

[Nathan-Fenner]

@Trashtalk217 Hi! I don't think I have the bandwidth to write anything right now, so please feel free to take the section (or let someone else do it)

[xyzw-io]

Materials from Jarl game for splash, per our conversation in Discord. Tried to include a screenshot, short and long video and gifs. Feel free to use any of these and/or edit them if you need: https://drive.proton.me/urls/8N6BKM603R#Ipsw82zEed52

Here are the links for this project (if only one can be used, the first one is the best):

Should the splash image GIF be converted into a format that is smaller since folks will see it loading on opening the page? Atm it's 11.6 MB; as a WebP it could be approx. 5.4 MB.

Good call. Done!

[xyzw-io]

@cart here is the same webp, but made from original video with higher res better preserving pixel art details. I hope 3.8mb is acceptable size): output.webp.zip

Attached as zip, because GH does not allow webp attachments.

[NiklasEi]

@xyzw-io the game looks awesome! Would it be possible to get a clip without the cursor in the middle of the scene?
