There is a bug related to relative values. Maybe that was what you encountered?
There will be a point release soon with a fix for that bug. In the mean
time you can just set database path to an absolute path.

You should not have to change your configuration to work with 0.32,
other than temporarily making sure database.path has an absolute value.
If you have a configuration file that works with 0.31 and not with 0.32,

Note that the ".notmuch" should not be included in database.path.

That's correct. Notmuch does not delete mail files.
