wiige I had posted the Upgrade Guide at here and working on spine-unity documentation update.

Awesome, thanks very much!

wiige your diff file is highly effective on locating documentation changes, is there any unified way I can track other documentation changes like spine-phaser 运行时文档 or spine-godot 运行时文档?

Very glad it helps! I created the diffs the following way, using git-bash when using Windows:

1. Create a directory for the documents to be tracked.
2. git init . to create a simple local git repository at this directory.
3. Create your document file like spine-unity.md and paste the current page content in it.
4. git add spine-unity.md and git commit the addition.
5. Then after modifying the document, again git add spine-unity.md and git commit the changes.
6. Then use git to view the diff between versions. I used git diff @~1 @ | clip to copy the diff between the previous (@~1) and the last commit (@) to the clipboard, then I paste it at https://diffy.org to share it with others.

I've shared the precise steps in case it helps others.

wiige Thank you for your thoughtful suggestion! We have considered the same thing and looked into it, but have not yet found the best way to use it with our CMS.
Whatever method we use, it will probably not be public outside of our team, but at least if I can track the updates properly, I will be able to contact you in a more efficient way.
We don't want to put any additional burden on you, so we would appreciate it if you would wait until we can prepare a proper procedure.

@wiige Apologies for my late reply, I was attending a conference (Reboot Develop Blue) last week and have just come back to the office. Thank you very much for your updates and for including the 4.2 update already as well! We have updated the website accordingly.

@wiige We have added a posting and a line to the 4.1 to 4.2 Upgrade Guide:
Posting added:
https://esotericsoftware.com/forum/d/26006-spine-unity-41-to-42-upgrade-guide/3
Line added to top-most posting (below the 3. bullet point):
[*] Replace any occurrances of `SkeletonGraphicRenderTexture.quadRawImage` with `quadMaskableGraphic`, change the type from `RawImage` to `MaskableGraphic`.[/*]
It would be great if you could add it at the Chinese 4.1 to 4.2 Upgrade Guide as well!

In the posting, you could skip the excerpt from the changelog, since we normally don't translate the changelog. It's the block starting with "> * SkeletonGraphicRenderTexture example component: protected RawImage quadRawImage was changed [..]".

wiige You are right! So if you could add the translation to the thread as a reply, I will edit the original thread and add the addition. Thanks in advance!

wiige Thank you! I've updated the main post.

@wiige Thanks very much for the quick translation! ️

(I just realized I had posted this on another thread. My apologies!)
Hi, @wiige. We would like to inform you that we have added the new documentation for the spine-sdl runtime: https://esotericsoftware.com/spine-sdl
If you are interested, it would be appreciated if you could translate it for us.

We are also working on documentation for the documentations for the spine-pixi runtime and spine-haxe runtime, which will probably be available soon.
Now that the 4.2 feature development and bug fixes have settled down, we are actively working on the documentation. So document additions and updates may become more frequent.

wiige Great, I reflected your translation and it looks perfect!: https://zh.esotericsoftware.com/spine-sdl
Thank you for always being willing to help!

@wiige We have recently split the spine-unity documentation page into multiple pages, and improved the documentation in the installation section since we noticed it was not so clearly structured and missing a few things.

I've created a step-by-step guide on what best to change in which order with links to diffs (and commit URLs, which unfortunately reference a private repository and only serve the purpose so that we later know which change was which). I hope that the guide helps keeping the work as minimal as possible, please let me know if anything is unclear or confusing. I've also uploaded the relevant .md files in case that helps (link see the notes txt file below). In general there should not be much to translate (except for additions in the Installation section), mostly moving text around to the right places, and updating cross-references.

It would be great if you could also split and update the Chinese spine-unity page in the same way. Thanks again for all your hard work!

@wiige I would like to inform you that the documentation page for the Spine Web Player has been updated. For now, the corrected or added sections have been replaced with English text:
https://zh.esotericsoftware.com/spine-player#%E5%A4%A7%E5%8A%9F%E5%91%8A%E6%88%90

For some reason, the diff didn't load properly on diffy.org, so I've uploaded the differences here:
https://www.diffchecker.com/WrCxqkdc/
(Most of the updates are code updates, and the only updates that require translation are the "JSON, binary, and atlas URL" section and the "Embedding data" section.)
