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 migration_variation and track_migration_op methods on LDClient.
Changed:
Raised pyyaml dependency to >=5.3.
Removed:
Python 3.7 support was removed.
The legacy user format for contexts is no longer supported. To learn more, read the Contexts documentation.
Methods which originally took a Context or a dict now only accept a Context.
Previously deprecated config options user_cache_size, user_cache_time, user_keys_capacity, user_keys_flush_interval, and private_attribute_names have been removed.
Previously deprecated test data flag builder method variation_for_all_users has been removed.
