5.3.0 (31 October 2017)

New Features

• With the period filter and field_stats, it is useful to match indices
  that fit within the period, rather than just their start dates. This
  is now possible with intersect. See more in the documentation.
  Requested in #1045. (untergeek)
• Add a restore function to curator_cli singleton. Mentioned in
  #851 (alexef)
• Add pattern to the count filter. This is particularly useful
  when working with rollover indices. Requested in #1044 (untergeek)
• The es_repo_mgr create command now can take skip_repo_fs_check as
  an argument (default is False) #1072 (alexef)
• Add pattern_type feature expansion to the period filter. The
  default behavior is pattern_type='relative', which preserves existing
  behaviors so users with existing configurations can continue to use them
  without interruption. The new pattern_type is absolute, which
  allows you to specify hard dates for date_from and date_to, while
  date_from_format and date_to_format are strftime strings to
  interpret the from and to dates. Requested in #1047 (untergeek)
• Add copy_aliases option to the shrink action. So this option is
  only set in the shrink action. The default value of the option is
  copy_aliases: 'False' and it does nothing. If you set to
  copy_aliases: 'True', you could copy the aliases from the source index
  to the target index. Requested in #1060 (monkey3199)
• IAM Credentials can now be retrieved from the environment using the Boto3
  Credentials provider. #1084 (kobuskc)

Bug Fixes

• Delete the target index (if it exists) in the event that a shrink fails.
  Requested in #1058 (untergeek)
• Fixed an integration test that could fail in the waning days of a month.
• Fix build system anomalies for both unix and windows.

Documentation

• Set repository access to be https by default.
• Add documentation for copy_aliases option.
