It looks like my 0.99.121.1 version is sending a request to https://browser.kagi.com/updates/13_0/appcast.xml
to get the latest version.
The response of this only returns https://browser.kagi.com/updates/13_0/121.1.zip
as the latest version - even tho the release notes suggests that release 0.99.122 is out.
My thoughts
Could it be something with the minimumSystemVersion: 13.0
where the latest version 0.99.122 is not in that 13_0
folder?
EDIT:
The version 0.99.122 does exist in the 13_0
folder - but for some reason not showing up when you send the request to get the latest update. Check my latest reply for how to update manually.
