Retrobatch 2.3 has been released. Some of the highlights:

Image Diffing: You can now compare your modified image against the original image using new handy new toolbar modes, or keyboard shortcuts.

PDF Rasterizer (Pro only): Convert all vector and text components of a PDF to full page images (handy for folks who want to "bake" their PDFs so text or elements can't be removed to find hidden information).

Send Notification node: Does what it sounds like — send out system notifications for when a workflow starts, ends, or for each image processed.

The Write node now has options to make indexed PNG files. This replaces the dedicated "Indexed PNG" node, so it's all wrapped together in a single node now.

There are little changes and bug fixes of course. The full release notes are available as usual. If you already have Retrobatch 2 installed, use the Retrobatch ▸ Check for Updates… menu item to update to the latest version.

One thing I did, which isn't in the release notes, is the preview canvas got a big upgrade as far as zooming, panning, and deep color support. I did a lot of refactoring when I was implementing the image diffing tools because I wanted to bring that feature to Acorn as well. So with some smart subclassing and such, I've got a shared Metal accelerated canvas that works for both Acorn and Retrobatch. This new class is used in quite a few places in the next release of Acorn (Web Export, RAW Image preview, New View windows, etc), and obviously in Retrobatch's main preview window. It's nice having a fully built out class that can I can just drop in for standard image editing behaviors.
