Great answer! Thanks a lot.

Thanks for the answer!

Just wondering if there should be some kind of prompt or message for people when downloading 5.7.4 to update their marketplace themes?

At the moment, if we develop a theme for the marketplace and put html5-shiv.js and respond.js in our theme header, the js files will be duplicated. So I am assuming the idea is that we hold off adding those js files into our themes until 5.7.4 is available.

I am imagining the situation where a user updates their concrete5 core to 5.7.4, but not their marketplace theme, and then find problems with their site and wonders why :)

people should stay up to date with their packages regardless. That's kind of the responsibility of owning a website: keeping your stuff up to date, and knowing what to do otherwise.

Just my two cents.

It's kind of like driving. You own the responsibility of maintaining your car, whether you do it, or a mechanic does it.

Developers can check for the concrete5 version number in a theme, and if version is lower/higher than version 7.x.x do this, otherwise do that (or do nothing). So you can already prepare for this if you have one or multiple themes in the store. You just have to include some if/else for all version compatibility!

Thanks, Ramonleenders, that's an idea. I guess we won't know for sure before 5.7.4 is out whether it will in fact have the js files removed, so I suppose we will have to wait to see.

I know that people should update their themes, but sometimes people don't as they may not think there is any special need to do so. Just thought a prompt could be helpful in this case....

I've recently read about this and saw an issue on Github. As it seems, it will be in the new version, see the commit here:

https://github.com/concrete5/concrete5-5.7.0/commit/0971447ce11de35a...

You can see the page_theme.php change too!

Html5-shiv.js and respond.js will become assets that come with concrete5 and can be required in page_theme.php.

Thanks ramonleenders and MrKDilkington, that's good to hear!
