**Full Changelog**: https://github.com/zwicker-group/py-pde/compare/0.33.0...0.33.1

Release with minor improvements, but also some breaking of backwards compatibility. In particular, we made the definition of cell coordinates more precise, which previously was used inconsistently. Two different versions of cell coordinates have been used where integral coordinates either refer to the cell center or its left edge. We now define cell coordinates to use the latter, since then the integral part denotes the cell, while the fractional part denotes the position within the cell.
