Description of the changes in your PR

To display changelogs in F-Droid and on their website, the changelog files need to be named like this: version_code.txt As you use different version codes, you should rename the changelog files and create new ones, when there are additional releases. I am currently working on an improved download section on our website and added NewPipe legacy to it. I need to get the changelog info from GitHub to display it on the website by using our web API. I'd also like to integrate viewing changelogs in the app later.

Fixes the following issue(s)

• Fix crash and empyt changelog in web API

Testing apk

Not needed as only metadata is changed.

Agreement

Don't forget how certain versions don't have Legacy versions, so the content of the changelog should also be changed.

Correct, but I don't think that this is necessary for old releases. I've set the number of processed changelogs to 1 for now and will increase it once there are more correctly named changelogs.
