This new alpha build introduces 8 new effects, fixes some crashes and other glitches, fixes compatibility with some old plugins, and adds some debugging options to assist with the WINE effort.

You can read more about 5.2 and what it includes by reading the release notes for the first alpha.

The new effects will be discussed more in the final release notes for 5.2, when the time comes, but here are some previews for now. Each new effect is also available for plugins to use in their Direct2D effect graphs.

(This isn’t actually a very good image to use for showcasing this effect. I’ll have a better example for the final release notes.)

Here are several examples for this one, which has many different modes you can experiment with:

• Added extension methods on IFileTypesServiceFactory for plugin developers: LoadFileAsDocument, TryLoadFileAsDocument, LoadFileAsBitmap, and TryLoadFileAsBitmap.
