This one’s definitely a recommended upgrade. It contains a few bug fixes that should remedy some obnoxious behavior you might notice in the previous alpha version.
Aside from bug fixes, this version now allows for sub-extractor patterns to be applied in sequence. It’s not something that’s often needed, but once in a while it can be handy (and even necessary).
Feel free to give it a try and let us know of any more trouble. As always, be sure to back up your work before upgrading to an alpha version.
