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.

• 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.

Added

• New Experiment: Image Editing via prompt-based image refining in the Post Editor and Media Library (#292).
• New Experiment: Image Editing via expanding or removing background and removing or replacing items in the Media Libary (#305, #312).

Changed

• Rename the plugin from "AI Experiments" to "AI" (#287).
• Replace Invalid_Experiment_Exception with _doing_it_wrong() (#303).
• Rename hook prefixes in helpers.php (#315).
• Rename plugin constants to WPAI_* (#317).
• Refactor the upgrade routine and add v0.6.0 migrations (#321).
• Move the Generate Alt Text button to the new Content tab for improved discoverability (#306).
• Remove stray "AI" references from UI for improved consistency (#320).
• Update documentation (#314).

Fixed

• Remove duplicate error display in the Generate Alt Text flow (#255).
