This new branch was released to allow to export Input Formats, Wysiwyg profiles and maybe other modules objects that works with entities provided by drupal core that doesn't have machine names.
Exportables 2.x doesn't include a UI like version 1.x. Even more, a lot of code from exportables 1.x was not included into 2.x. The last version of Ctools (1.7) allows to define JOINS between tables to generate exports, therefore it is probable that the original code from 1.x will not be included in this branch, since there are other methods to do this.
<strong>This is the first beta of this module, and shouldn't be used in productions sites</strong>. The most important reason for this release is to make easier to test <a href ="http://drupal.org/project/input_formats">Input Formats</a> Beta-2 and the wysiwyg patch that allows to export profiles to code. See: [#624018]
There is no upgrade path from 1.x, so please uninstall Exportables 1.x before installing this release.
If you were using Exportables to load your taxonomy vocabularies from code, now this capability is included in Features-1.x-beta10 and was removed from exportables 2.x.
