Since yesterday we encounter problems running Appveyor for doxygen compilations. We get:
WARNING: You are using pip version 19.3.1; however, version 20.2.4 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Reference to build:

Any idea?

    Looking at the error pkg_resources.ContextualVersionConflict: (urllib3 1.26.0 I suspect there was a version bump in urllib3 - one of conan dependencies. Indeed, last successful build installs urllib-1.25.11 and the failing build installs urllib-1.26.0. Oh, and there is a newer version of conan 1.31.2 already released which fixes the issue with liburl3:

    Thanks for te answer, does this mean that on the doxygen side something has to be done or on the Appveyor side?

    I don't know. Anyway, the AppVeyor VM images haven't been changed - if there are overnight issues they are definitely "upstream" ones.

    OK thanks looks like we have to wait for our next doxygen build so that the newest version of conan can be used.
