v3.1.0

Changed

• Allow the orquesta st2kv function to return default for nonexistent key. (improvement) #4678
• Update requests library to latest version (2.22.0) in requirements. (improvement) #4680
• Disallow "decrypt_kv" filter to be specified in the config for values that are marked as
  "secret: True" in the schema. (improvement) #4709
• Upgrade tooz library to latest stable version (1.65.0) so it uses latest version of
  grpcio library. (improvement) #4713
• Update st2-pack-install and st2-pack-download CLI command so it supports installing
  packs from local directories which are not git repositories. (improvement) #4713

Fixed

• Fix orquesta st2kv to return empty string and null values. (bug fix) #4678
• Allow tasks defined in the same task transition with fail to run for orquesta. (bug fix)
• Fix workflow service to handle unexpected coordinator and database errors. (bug fix) #4704 #4705
• Fix filter to_yaml_string to handle mongoengine base types for dict and list. (bug fix) #4700
• Fix timeout handling in the Python runner. In some scenarios where action would time out before
  producing any output (stdout, stder), timeout was not correctly propagated to the user. (bug fix)
  #4713
• Update st2common/setup.py file so it correctly declares all the dependencies and script
  files it provides. This way st2-pack-* commands can be used in a standalone fashion just by
  installing st2common Python package and nothing else. (bug fix) #4713
• Fix st2-pack-download command so it works in the environments where sudo binary is not
  available (e.g. Docker). (bug fix) #4713
