[6.0.0] - 2023-10-23

The latest version of this SDK supports the ability to manage migrations or modernizations, using migration flags. You might use this functionality if you are optimizing queries, upgrading to new tech stacks, migrating from one database to another, or other similar technology changes. Migration flags are part of LaunchDarkly's Early Access Program. This feature is available to all LaunchDarkly customers but may undergo additional changes before it is finalized.

For detailed information about this version, refer to the list below. For information on how to upgrade from the previous version, read the migration guide.

Added:

• A new Migrator type which provides an out-of-the-box configurable migration framework.
• For more advanced use cases, added new migrationVariation and trackMigrationOperation methods on LDClient.

Removed:

• PHP 8.0 support was removed.
• The legacy user format for contexts is no longer supported. To learn more, read the Contexts documentation.
• Methods which originally took an LDContext or an LDUser now only accept an LDContext.
• Previously deprecated test data flag builder methods variationForAllUsers, valueForAllUsers, and clearUserTargets have been removed.

[5.2.0] - 2023-10-23

Deprecated:

• LDUser is now deprecated in favor of LDContext.

[5.1.1] - 2023-07-12

Changed:

• Invalid context log message now includes the flag key as part of the Psr\Log context. (Thanks, mrtus!)
• Error logging now includes the exception in the Psr\Log exception context key. (Thanks, mrtus!)

[5.1.0] - 2023-01-31

Added:

• Introduced support for an application_info config property which sets application metadata that may be used in LaunchDarkly analytics or other product features. This does not affect feature flag evaluations.

[4.3.0] - 2023-01-31

Added:

• Introduced support for an application_info config property which sets application metadata that may be used in LaunchDarkly analytics or other product features. This does not affect feature flag evaluations.

[5.0.0] - 2023-01-04

The latest version of this SDK supports LaunchDarkly's new custom contexts feature. Contexts are an evolution of a previously-existing concept, "users." Contexts let you create targeting rules for feature flags based on a variety of different information, including attributes pertaining to users, organizations, devices, and more. You can even combine contexts to create "multi-contexts."

This feature is only available to members of LaunchDarkly's Early Access Program (EAP). If you're in the EAP, you can use contexts by updating your SDK to the latest version and, if applicable, updating your Relay Proxy. Outdated SDK versions do not support contexts, and will cause unpredictable flag evaluation behavior.

If you are not in the EAP, only use single contexts of kind "user", or continue to use the user type if available. If you try to create contexts, the context will be sent to LaunchDarkly, but any data not related to the user object will be ignored.

For detailed information about this version, please refer to the list below. For information on how to upgrade from the previous version, please read the migration guide.

Added:

• The type LDContext defines the new "context" model. "Contexts" are a replacement for the earlier concept of "users"; they can be populated with attributes in more or less the same way as before, but they also support new behaviors. To learn more, read the documentation.
• For all SDK methods that took an LDUser parameter, the parameter type can now be either LDUser or LDContext. The SDK still supports LDUser for now, but LDContext is the preferred model and LDUser may be removed in a future version.

Changed (breaking changes from 4.x):

• It was previously allowable to set a user key to an empty string. In the new context model, the key is not allowed to be empty. Trying to use an empty key will cause evaluations to fail and return the default value.
• There is no longer such a thing as a secondary meta-attribute that affects percentage rollouts. If you set an attribute with that name in LDContext, it will simply be a custom attribute like any other.
• Component interface types like EventPublisher and FeatureRequester which applications are unlikely to reference directly (except when defining a custom component implementation) have been moved out of the main namespace into a new namespace, LaunchDarkly\Subsystems.

Changed (requirements/dependencies/build):

• The minimum PHP version is now 8.0.

Changed (behavioral changes):

• The SDK is now more strictly compliant with the LaunchDarkly specification for date and semantic version values. This means that some values that might have been accepted in the past, which other SDKs would not accept, are now correctly considered invalid. Please review the LaunchDarkly documentation on Using date/time and semantic version operators.
• Analytics event data now uses a new JSON schema due to differences between the context model and the old user model.

Fixed:

• Fixed a bug in the parsing of string values in feature flags and user attributes when they were referenced with date/time operators in a targeting rule. As described in LaunchDarkly documentation, such values must use the RFC3339 date/time format; the SDK was also accepting strings in other formats (for instance, ones that did not have a time or a time zone), which would cause undefined behavior inconsistent with evaluations done by other LaunchDarkly services. This fix ensures that all targeting rules that reference an invalid date/time value are a non-match, and does not affect how the SDK treats values that are in the correct format.
• The SDK was allowing numeric values to be treated as semantic versions in targeting rules. It now correctly only allows strings, as described in LaunchDarkly documentation.

Removed:

• Removed all types, fields, and methods that were deprecated as of the most recent 4.x release.
• Removed the secondary meta-attribute in LDUser and LDUserBuilder.
• The alias method no longer exists because alias events are not needed in the new context model.
• The inline_users_in_events option no longer exists because it is not relevant in the new context model.
