This release makes the image uploading use relative paths for images by default. This means the image URLs uploaded to posts will be in the format /api/qeta/attachments/uuid instead https://my-idp/api/qeta/attachments/uuid. If you are running your backend on a different URL than your frontend, you can disable this by setting the config value qeta.storage.useRelativeUrls to false.
This is to fix bug #310, but it doesn't automatically fix the existing image URLs in post contents.
