I've been working on the latest release of Tesseract for the last few weeks, and I'm happy to announce the first beta release of the upcoming 1.4.0 series.
I daily drive my dev version throughout the development process, so all the bugs I've encountered/introduced should be fixed. The beta test on the main instance is more of a formality and final shakedown. That said, please report any bugs you encounter either through Github or by describing them in a comment here.
1.4.0 is a significant update as it drops all backwards compatibility with the 0.18.x API and introduces several new features. It's also had some additional polish since 1.3.0 and added things that have been requested for quite some time (pasting images into post/comments, etc).
As always: thanks in advance for being my beta testers. Appreciate it!
