# Changes to mh-e

mh-e had a fairly major facelift between Versions 3 and 4. The differences between Versions 4 and 5 from the user's viewpoint are relatively minor. The prompting order for the folder and message number in a couple of functions had been switched inadvertently in Version 4. Version 5 switches the order back. The ``+inbox'` folder is no longer hard-coded, but rather uses the ``Inbox'` MH Profile entry. See the file ``etc/MH-E-NEWS'` in the Emacs distribution for more details on the changes.

This section documents the changes between Version 3 and newer versions so that you'll know which commands to use (or which commands you won't have) in case you're stuck with an old version.

The following tables summarize the changes to buffer names, commands and variables.
