Our policy is to never remove any functionality between two versions.  
We replace the functionality with new functionality and print out  
warnings whenever you use the deprecated functions. We also add this  
to the documenation in the software and the UPGRADE.TXT file. So the  
functionality that you lost in 1.4 was old 1.0 functions that was  
marked as deprecated in 1.2 and removed in 1.4.

We might want to be more informative about those changes. We need to  
make a clear list of things you need to start changing as a user of  
1.4 to prepare for lost functionality in 1.6. This information already  
exist, but should maybe be a bit more public.

In some cases we do have to change in a dramatic way and can't  
preserve the old functionality to solve a bug in the software. This  
requires thorough discussion in the developer group and is something  
we really want to avoid at all costs. If this happens, it's clearly  
documented in the software.

Thank you for your feedback, it's important to us.
