Hi,
the first image scaler based on Debian jessie is now enabled in
production. Despite other changes this also provides an update
of librsvg to 2.40.16 which fixes several long-standing bugs in
SVG rendering:

(Please note that this currently only applies to one out of eight
systems, I'll send a followup once all scalers are migrated).
This has been tested quite a bit and no problems were found, but if
you notice anything unusual related to image/SVG scaling (e.g. due to
font changes) please drop a note in #wikimedia-operations or file a
Phabricator task and add the Operations project.
Cheers,
Moritz
