metadata implicite newer version available, but not published (e.g. MPDroid, BookCatalogue)
Studying the metadata.txt files ans the documentation documentation https://f-droid.org/docs/Build_Metadata_Reference the following differences have come to my attentions.
I'm not sure if it is a bug or a personal misunderstanding. Due to the lack of response to https://forum.f-droid.org/t/metadata-txt-some-application-are-not-published-sinced-years-e-g-mpdroid-book-catalogue/1025 I presume it is really a bug ;-)
I have taken a look at https://gitlab.com/fdroid/fdroiddata/blob/master/metadata/com.namelessdev.mpdroid.txt
Current Version:1.07.2 Final Current Version Code:54
According to https://f-droid.org/docs/Build_Metadata_Reference/#Current-Version
1.07.2 Final should be the freshest version.
So I tried to fetch: https://f-droid.org/repo/com.namelessdev.mpdroid_54.apk - but it isn't available
I compare this now with: https://f-droid.org/packages/com.namelessdev.mpdroid/ Here I see that the Version1.0 with Version Code 20 is advertised (from 2012)
Another look I have taken was: https://gitlab.com/fdroid/fdroiddata/blob/master/metadata/com.eleybourn.bookcatalogue.txt
Here I see:
Current Version:5.1.1 Current Version Code:168
According to the Build entries I understand that this version build is disabled. So my next Idea was to read reverse the build entries till I found the first not-disabled entry. This would be here the Version 5.0.7 (Version Code: 151).
As above for MPDroid I can't either download the Version Code 151 (or 168)
So I check again https://f-droid.org/packages/com.eleybourn.bookcatalogue/ Here I see that the Version 3.8.1 (Version Code 70) from 2011 is the last available version.
