# Warnings are errors. A DeprecationWarning is a change that will break the
# build later, and the only reliable time to deal with one is when it first
# appears - once a few are tolerated, the new one is invisible in the noise.
#
# When a dependency starts warning about something you cannot fix yet, add a
# narrow ignore here rather than relaxing this line, e.g.:
#
#   ignore:some message regex:DeprecationWarning:the_package.*
#
# Keep each ignore as specific as the warning it silences, so it stops applying
# once the dependency is fixed.
