----------------

- Support for big (tiled) Images. This is a major change ([243](https://github.com/ome/omero-figure/pull/243))
- Allow loading Polygons and Polylines from OMERO to add to Images ([253](https://github.com/ome/omero-figure/pull/253))
- Open-with Figure and adding Images now preserves the order of Images ([275](https://github.com/ome/omero-figure/pull/275))
- Support for adding label of T-index to time-lapse Images ([276](https://github.com/ome/omero-figure/pull/276))
- Show a spinner while loading new Images ([279](https://github.com/ome/omero-figure/pull/279))
- Stroke-width of ROIs are now based on page points, not on panel pixel sizes ([281](https://github.com/ome/omero-figure/pull/281))

Developers:

- Use test_infra to test listing of figure files ([270](https://github.com/ome/omero-figure/pull/270))
- Breaking change in figure JSON model. Stroke-widths changed (see above) and export-dpi renamed to min-export-dpi
- Use shape-editor 4.0.0 to support Polygons and Polylines ([253](https://github.com/ome/omero-figure/pull/253)) and not scale stroke-width

This release also upgrades the required version of OMERO
to 5.4.0 or newer.
