Released 2026-08-04. Upgrading from v0.3.1.

The AI provider packaging release. Nothing here is breaking, but if your AI provider worked in development and failed in production, this is the release that fixes it.

Added

• AI provider subpackages. Two new entry points, one per provider, each exporting a plugin you register in your ChaiBuilder config: an OpenRouter provider and an OpenAI compatible provider. Register the one you use and set its environment variables, and requests route to that provider instead of the default gateway.
• Each provider plugin activates only when its own environment variables are present, so a registered but unconfigured provider leaves the default gateway in charge. That means you can commit the registration and let the environment decide.

Changed

• aiPlugin is renamed to aiAdvancedPlugin, to separate the advanced AI feature set from provider registration. Both aiPlugin and the older aiProPlugin remain as deprecated aliases and continue to work, along with their option types. Nothing needs to change on upgrade, but new projects should use the new name.
• Registering a provider plugin is now the recommended way to point AI at something other than the default gateway. ChaiBuilder still detects installed provider SDKs at runtime without registration, which is convenient locally, but that detection is invisible to the bundler. A production build can drop the package from its output, and the AI panel then reports that the provider is configured but could not be loaded. Registering the plugin makes the dependency visible to the build, so it survives. See AI Setup.

Fixed

• HTML spelled attributes on blocks are no longer dropped. Attributes authored the way HTML spells them, such as class, for, colspan and datetime, are now translated to the names React expects before a block renders. Previously React warned in the console and silently discarded the attribute, so authored markup lost styling, table spans, form label associations and machine readable dates.
• A rendering fix in the page dropdown in the builder header.
