I needed to check if the older version was better in terms of blocking ads with my regular expressions.
It now tells me
[i] FTL: up to date
[i] Warning: You are using FTL from a custom branch (v5.13) and might be missing future releases.
How do I get to remove this and let it go with the normal updates it finds? I get an update available in the admin space (cause there is the v5.14 available)
P.S.: there is something broken on pihole 5.9. I am reverting to 5.8.1
