Normally the beta version contains fixes hoping to fix problem with the previous version(s), then when the author is satisfied that the problem are resolved then a stable version is released. The b versions are beta test versions. So to answer your question it is 1.3.11; unless, there 1.3.12 beta or newer version.
With Google no longer supporting the File section here; other words, no longer allowing uploads. I would like to propose this question. How and where are we as a group going to get the new beta releases of the webmail add-on and updates its related add-ons? Eugene
