Re: [sage-release] Sage 9.2.rc1 released
I was mistaken. Even though I have system Singular-4.1.1_p2-r2 installed the subject doctest was actually using the Sage-provided Singular-4.1.1p2.p0.

Re: [sage-release] Sage 9.2.rc1 released
Hi Volker, could you perhaps review and merge https://trac.sagemath.org/ticket/30737 - this is something that touches sage-update-version, so you'd be the most natural reviewer - and it is meant to generate sane DOI records for Sage releases.

I confirm the singular crash on my Ubuntu 20.04 computer (9.2.rc1 build
incrementally from 9.2.rc0 with system Python (3.8.5) and Singular 4.1.1
installed as a spkg). It is permanent (crashes when run manually). The log
is attached. The doctest was passed with Sage 9.2.rc0.
