**Image formatting**
Added support for changing the format of images via the `handle-image-sizes` middleware (e.g. format SVG to png, jpeg, webp)
This change was required:
- Not all browsers support SVG favicons, so we need to convert them to PNGs
- We can't fit image resizing and formatting in the `serve-favicon` middleware: we need to store the resized image to avoid resizing on every request. This system was already present in the `handle-image-sizes` middleware.
To format an uploaded image:
- Original URL: https://localhost/blog/content/images/2022/05/giphy.gif
- To resize: https://localhost/blog/content/images/size/w256h256/2022/05/giphy.gif (already supported)
- To resize and format to webp: https://localhost/blog/content/images/size/w256h256/format/webp/2022/05/giphy.gif
- Animations are preserved when converting Gifs to Webp and in reverse, and also when only resizing (https://github.com/TryGhost/Ghost/issues/13319)
**Favicons**
- Custom favicons are no longer served via `/favicon.png` or `/favicon.ico` (only for default favicon), but use their full path
- Added support for uploading more image extensions in Ghost as a favicon: .jpg, .jpeg, .gif, .webp and .svg are now supported (already supported .png and .ico).
- File extensions other than jpg/jpeg, png, or ico will always get transformed to the image/png format to guarantee browser support (webp and svg images are not yet supported as favicons by all browsers).
For all image formats, other than .ico files:
- Allowed to upload images larger than 1000px in width and height, they will get cropped to 256x256px.
- Allowed uploading favicons that are not square. They will get cropped automatically.
- Allowed to upload larger files, up to 20MB (will get served at a lower file size after being resized)
For .svg files:
- The minimum size of 60x60px is no longer required.
For .ico files:
- The file size limit is increased to 200kb (coming from 100kb)

- These are all test files I missed in ffcd3fbe313b4a413833da9a7473376cb21246fd
We're going to be dropping the idea of having multiple versions of the API in each Ghost version.
Because this has not achieved the goal of making it easier to make breaking changes, but it has
created an ordinate amount of technical debt and maintenance overhead.
As we know this is going away in the next major, there is no benefit to us constantly running tests
that check if those versions still work, especially given how long they take.
Instead we're starting work to ensure that all of our test work on canary, and that canary has
excellent test coverage so that we can be sure that our one API version works really well and that
any changes, no matter how subtle are deliberate, tracked and understood.
- This is a minor bugbare, but it will affect some configuration I'm about to do for c8
- I've been wanting to do it for ages, middleware is plural all on it's own so it's an odd affectation in our codebase
- This also only exists in 2 places, everywhere else we use "middleware"
- Sadly it did result in a lot of churn as I did a full find and replace, but consistency is king!
- this is a small part of a bit of cleanup of our test files
- the goal is to make the existing tests clearer with a view to making it easier to write more tests
- this makes the test structure follow the codebase structure more closely
- eventually we will colocate the tests as we break the codebase down further
