Open Source replacement for WPML? [closed]

Since WPML is not free anymore and still one of the most used WordPress Translation Plugins, is there an open source project that keeps development going? Or something similar that replaces it?

I know there are other alternatives out there, but most have different approaches or features. I for example like the fact, that every translation is in it’s own post.

Try qtranslate…I use it religiously. Has some issues like with dates and times, but I always find a solution.
