CloudBees Feature Management - Java server changelog

CloudBees Feature Management is an advanced feature flagging solution that lets your development teams quickly build and deploy applications without compromising on safety. By providing a gradual release mechanism and a simple way to define target audiences, CloudBees Feature Management allows developers and product managers to optimize feature releases and customize the user experience. CloudBees Feature Management gives teams control over features that are in staging, production, or any environment in the deployment pipeline.

Sep 29, 2022: V5.0.8 Loading local storage and embedded configurations synchronously

  • Rox.Setup is now aware of new configurations fetched from network. Local storage configurations and embedded configurations are now loaded synchronously before the network call within Setup. Now the later one is used, guaranteeing that by the time the code after setup runs, flags are using the latest local configurations. Before this update, local configurations were loaded asynchronously.

    Refer to Flag update flow for more information.

  • Updating org.json dependency

May 20, 2022

  • European Union (EU) hosting has been removed.

January 21, 2022: V5.0.6 Shadowed network library update

  • Updated version of OkHttp to 3.12.13

2021-08-12: V5.0.5 New proxy capability

  • Added a proxy that supports servers or clients using CloudBees Feature Management SDKs with the following connection issues:

    • No internet access

    • Trouble connecting to CloudBees Feature Management services

    • Blocked by a firewall

    • Client does not have CORS permissions

    • Needing full control over network requests

      Refer to A proxy for CloudBees Feature Management for more information.

2021-07-19: V5.0.4

  • Fixed push notification bug

  • Adding EU hosting support

2021-06-03: V5.0.2

  • Fixed embedded configuration

2021-04-01: V5.0.1

  • Few internal bug fixes.

2021-03-28: V5.0.0

Breaking changes:

  • RoxVariant changed to RoxString

    • new RoxVariant("defaultStr", new String[] {"str1", "str2"}) ⇒ new RoxString("defaultStr", new String[] {"str1", "str2"}).

  • RoxEnumVariant renamed to RoxEnum.

    • new RoxEnumVariant<>(MyEnumType.Value) ⇒ new RoxEnum<>(MyEnumType.Value).

  • Functions input validations

    • Some trivial parameters (mostly type) validations were added to dynamicApi and flags constructions. For example: new RoxString(null) will raise an IllegalArgumentException as default cannot be null (default value of RoxString should be a string). Rox.dynamicApi.value(null, "defaultStr", ["str2", "str3"]) will raise an IllegalArgumentException because of null 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 CustomPropertyGenerator.generateProperty, ImpressionHandler.onImpression, ConfigurationFetchedHandler.onConfigurationFetched, DynamicPropertyRule.invoke) with try-catch in order to be in the right context. In case there will be an uncaught error, it will reach the Rox.setUserspaceUnhandledErrorHandler handler. You can use this handler for debugging, or for further error handling. A Throwable thrown within this handler will be written to log. If no setUserspaceUnhandledErrorHandler 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 (reportingValue, experiment, context) to (ImpressionEvent event). Besides name, value, and context properties, event also provides 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 getInt and getDouble 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.

  • Added RoxOptions.Builder.withDynamicPropertyRule.

  • Remote configurations were eliminated, please use flags instead:

    • new RoxConfigurationString ⇒ new RoxString

    • new RoxConfigurationInt ⇒ new RoxInt

    • new RoxConfigurationDouble ⇒ new RoxDouble

    • new RoxConfigurationBool ⇒ new RoxFlag
