0.6.0 – 2026-03-20

There are Breaking Changes in this release.

• Breaking Changes: Refactor Experiments to be a type of Feature, improving how functionality is organized and surfaced (#316).

The following classes have been removed. Anyone that was directly using these will need to make updates to utilize the correct replacements: Abstract_Experiment, Invalid_Experiment_Metadata_Exception, Invalid_Experiment_Exception, Experiment_Loader, Experiment_Registry.

• Breaking Changes: Standardize the Title Generation Ability to align with other registered Abilities (#227).

The ai/title-generation Ability now uses a context argument instead of a post_id argument in the input_schema. Anyone directly using this Ability will need to make updates to account for that.
