utACK
@jl2012 maybe post a signature done with your old key here for consistency?

[maflcko]

So what happened to the old key?

$ gpg --fingerprint jl2012
pub   4096R/B3936517 2015-10-16
      Key fingerprint = D3CC 1772 8600 5BB8 FF67  3294 C524 2A1A B393 6517

Concept NACK from me. This is the same key, it seems.

[jl2012]

@MarcoFalke The self-signature of the key was expired in August. This one has the new signature

At some point it was decided not to update keys in this repository unless the actual key changed, to minimize diff noise (see e.g. discussion in #8547).

People are however advised to run gpg --refresh-keys after importing: #8603

[jl2012]

OK, closing
