2021-03-29: V5.0.0

Breaking changes:

  • Variant changed to RoxString

    • Variant('default_string', ['string_1', 'string_2']) ⇒ RoxString('default_string', ['string_1', 'string_2'])

  • Functions input validations

    • Some trivial parameters (mostly type) validations were added to dynamic_api and flags constructions. For example: RoxString(None) will raise an TypeError as default cannot be None (default value of RoxString should be a string and defaults to an empty string if no default is provided). Rox.dynamic_api.value(None, 'default_string', ['string_2', 'string_3']) will raise an TypeError because of None flag name (name should always be a string)

Fixes and Additions:

  • Can use register without a namespace:

    • register(container) will register the container under an empty string namespace (multiple register calls with the same namespaces are still not allowed!)

  • Added a User Space Error handling

    • It is recommended to wrap all handlers used in Rox platform (all Rox.set_custom_<…​>_property, RoxOptions.impression_handler, RoxOptions.configuration_fetched_handler, RoxOptions.dynamic_properties_rule) with try-except in order to be in the right context. In case there will be an uncaught error, it will reach the Rox.set_userspace_unhandled_error_handler handler. You can use this handler for debugging, or for further error handling. An Error thrown within this handler will be written to log. If no set_userspace_unhandled_error_handler was set, errors will be written to the log.

  • Analytics / impressions

    • Starting with SDK 5, flags will always send impressions after setup (not only when targeting is enabled on the dashboard)

  • Impression handler parameters change

    • As experiments were removed, impressions handler signature was changed from (reporting_value, experiment, context) to (reporting_value, context). reporting_value now also has a Targeting (boolean) property, indicating the flag was evaluated by using the dashboard configurations.

  • New Flag Types Int/Double

    • In addition to RoxFlag and RoxString, we also added RoxInt and RoxDouble

    • DynamicApi was also updated with matching get_int and get_double methods

  • Added a graceful Rox.shutdown

    • In order to clean all background Tasks

    • multiple Rox.setup calls will be ignored if Rox wasn’t Shutdown in between
