This patch is for 2013.10, not 2013.07, but I prefer raising the issue as early as possible. If there is no way to make things smoother, then I think the 2013.10 release notes should contain a red, blinking, paragraph about this. I would *hate* it if people were not warned and given a method to port their current environment setting over. Possibly even, the 2013.07 could have a warning about the change to come, so that people have a better chance yet to prepare for the change. Amicalement, -- Albert.
