0.38.0

The main new features are a new storage (MovieStorage), which stores data in a compressed movie, thus saving space at the expense of reduced accuracy. The release also provides a new solver and additional improvements.

0.36.0

This version contains a larger reorganization of the grid classes, where we now separated the calculations concerning coordinate systems in separate classes. This will make code cleaner in the longterm and allow us to support additional features more easily. However, this might also have introduced some bugs in the short-term.

• Add ylim argument for line plots by @david-zwicker in #520
• Improved coordinate conversion capabilities by @david-zwicker in #523
• Improve merging color channels for field collections by @david-zwicker in #525
• Separate classes describing coordinate systems by @david-zwicker in #527

0.33.2

Full Changelog: 0.33.0...0.33.1

0.33.0

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.
