Hello Patrick,
We continue adapting all the customizations and features your current production server has to our newest version. We are doing some work on the Collections management that will impact the way the Collections are managed.
So We are postponing moving you to a newer version until we finish all the work on Collections, this way the impact of change on your current workflow will be less.
Meanwhile we decided to patch your current server for the 2 issues pending:
1) Closing the image preview with the X icon
2) Preview images not being displayed when the Collection (Proyect) has an "&" character in the name.
I tested the patches and they work ok in your current Production server.
We will keep you posted in following weeks to let you know about the progress on Collections in the newer version and then we can restart the moving process.
Please let us know if you see the issues fixed in your side, it may require a Browser restart since some of the changes were applied on Java Script components.
