maestrod-0.5.0

First public release. Value-compatible with the internal 0.3.4 chart; the
following defaults changed — set them explicitly to preserve old behaviour:

  repository: <account>.dkr.ecr.eu-west-1.amazonaws.com/maestrod  # now pspdfkit/maestrod

  pullPolicy: Always                                                   # now IfNotPresent
imagePullSecrets: <...>
podLabels: { component_name: maestrod }  # now {}

  registryAuthSecretName: "<...>" # now ""
