Well, we’ve been a bit delinquent in announcing new alphas. This most recent one fixes a long-standing, but rarely seen bug where extractor patterns could magically appear where they shouldn’t. There are also quite a few other little niceties and bug fixes since 3.0.14a, when we last announced an update.
For those interested, feel free to upgrade in the usual way. As always, this is alpha code, so please back up your work before upgrading.
