The following notes correspond to a migration from 2.4.2 to 2.5.0. If you are migrating from an earlier release, please also refer to previous migration notes.
If desired, you can install 2 versions. See this blog post.
Note: There is more error checking as well, such that new errors now may be raised causing code to break if it did not have full error checking in place already. For quick resolution, you can use a legacy mode. Though eventually all error checking will need to be put in place.
