Bug fixes
- Patch some backward-incompatible changes to
validate_presence_of
that were
made in the last version. As of 4.1.0 the presence matcher now checks to
ensure that empty string will cause the record to be invalid (in addition to
nil, which it was already checking against). However, this check was being
performed even if the attribute or column the presence matcher is being run
against didn't support being set to an empty string. This releases fixes this.
