Questions about this new 2.6.0-dev version

I uploaded the latest version litecart-2.6.0-dev-f34779 to test the compatibility of my template (on 2.5.5) and to adapt it to the new php code. I had some questions about this new (development) 2.6 version. Where is the right forum to ask these kinds of questions about development versions?

Same as other version.

Problems -> Errors and Troubleshooting
Template -> Templates and CSS
If you are not sure -> General Discussions

Like Dodo said, like any other version.
Keep putting "2.6.0-dev" in the topic so everyone knows it's a development release you are discussing.
