1.7.0

[1.7.0]

Added

• The ability to override any value of the celery configuration thru app.yaml in celery.override.
• Support and faq entry for pgen with merlin run --pgen and optional --parg.
• Documentation on level_max_dirs.
• Easier-to-read provenance specs.
• Documentation on the new 3 types of provenance spec.

Fixed

• Flux test example data collection for new versions of flux.
• Fixed Docker ubuntu version.
• Removed expansion of env variables in shell sections (cmd and restart) of provenance
  specs. This allows the shell command itself to expand environment variables, and gives
  users greater flexibility.
• Allowed environment variables to be properly expanded in study description.name.
• Tilde (~) now properly expands as part of a path in non-shell sections.
• The rediss cert_reqs keyword was changed to ssl_cert_reqs.

Changed

• Updated tutorial redis version to 6.0.5.
