This new version, recently release, provided us with two new features:
First, the ability to load widgets from your upload dir (to be more specific, wp-content/uploads/transposh/widgets), this is for everyone who created its own widget (maybe just changing a flag) and had problems updating the plugin because the current widget folder got overridden, this feature also opens up the possibility to share widgets with others.
The second feature is the addition of Google “rel=alternate hreflang” method, which is basically using fully qualified urls for each such reference instead of relative urls, this increases the size of your htmls by a lot (depending on the number of languages you support, just multiply this number by the size of address of your site and you can quickly add up 1k for each request for nothing). Our current recommandation is just to disable this feature, but if you want a better experience in Google’s webmaster tools, go ahead and have fun.
We hope you will enjoy this version, don’t hesitate to contact us for any bugs/feature requests.
I cannot make all languages active even I have chosen “Allow upgrading to full version” on settings page
You are correct, this was a problem in 1.0.1 when the upgrade to full won’t happen (needed to do that manually), however you may now upgrade to 1.0.2 which will upgrade to the full version.
