  • Stretch histogram shows a spinner when the histogram data is updating. [#2644]
  • Spectrum and image viewer bounds can now be set through the Plot Options UI. [#2604, #2649]
  • Opacity for spatial subsets is now adjustable from within Plot Options. [#2663]
  • Live-preview of aperture selection in plugins. [#2664, #2684]

Cubeviz

  • Calculated moments can now be output in velocity units. [#2584, #2588, #2665, #2697]
  • Added functionality to Collapse and Spectral Extraction plugins to save results to FITS file. [#2586]
  • Moment map plugin now supports linear per-spaxel continuum subtraction. [#2587]
  • Single-pixel subset tool now shows spectrum-at-spaxel on hover. [#2647]
  • Spectral extraction plugin re-organized into subsections to be more consistent with specviz2d. [#2676]
  • New aperture photometry plugin that can perform aperture photometry on selected cube slice. [#2666]

Imviz

  • There is now option for image rotation in Orientation (was Links Control) plugin. This feature requires WCS linking. [#2179, #2673, #2699]

Mosviz

Specviz

Specviz2d

  • Spectral extraction plugin: highlighting of active header section. [#2676]

API Changes

  • width argument in Line Analysis plugin is renamed to continuum_width and width will be removed in a future release. [#2587]
  • New API access to viz.data_labels, viewer.data_labels_visible, and viewer.data_labels_loaded. [#2626]

Imviz

  • Links Control plugin is now called Orientation. [#2179]
  • Linking by WCS will now always generate a hidden reference data layer without distortion. As a result, when WCS linked, the first loaded data is no longer the reference data. Additionally, if data is distorted, its distortion will show when linked by WCS. If there is also data without WCS, it can no longer be displayed when WCS linked. [#2179]

  • Aperture photometry (previously "Imviz Simple Aperture Photometry") now supports batch mode. [#2465]
  • Aperture photometry sum is now presented in scientific notation consistently. [#2530]

In Specviz, if a fully-finite spectrum with non-finite uncertainties is loaded, the uncertainties will be dropped so every datapoint isn't filtered. For other scenarios with non-finite uncertainties, there are appropriate warning messages displayed to alert users that data points are being filtered because of non-finite uncertainties (when flux is finite). [#2437]
  • Add swatches to color picker. [#2494]
  • Plot options now includes better support for scatter viewers, including toggling line visibility. [#2449]

Cubeviz

  • Fixed moment map losing WCS when being written out to FITS file. [#2431]
