  [#1401, #1642, #1643, #1636, #1641, #1634, #1635, #1637, #1658, #1640, #1657, #1639, #1699, #1701, #1702, #1708]

• Line Lists show which medium the catalog wavelengths were measured in,

• Added ability to set height of application widget using show method. [#1646]

• Add Common Galactic line lists, split Atomic/Ionic list with verified medium info [#1656]

Cubeviz

• Image viewers now have linked pan/zoom and linked box zoom. [#1596]

• Added ability to select spatial subset collapsed spectrum for Line Analysis. [#1583]

• Increased size of Cubeviz configuration from 600px to 750px. [#1638]

  a non-reference image if images are linked by WCS. [#1524]

• Calling imviz.load_data(data, data_label), where data_label is passed in

  this will crash because second positional argument is actually a
  parser_reference that is meant for internal use. [#1644]

  subset is deleted after a viewer is deleted. [#1649]

Mosviz

• New specviz2d.specviz helper property to directly access Specviz functionality from Specviz2d. [#1577]

API Changes

Imviz

• Imviz.load_static_regions_from_file() and Imviz.load_static_regions() are
  deprecated in favor of Imviz.load_regions_from_file() and Imviz.load_regions(),
  respectively. This is because some region shapes can be made interactive now even though
  they are loaded from API. The new methods have slightly different API signatures, please
  read the API documentation carefully before use. [#1463]

Bug Fixes

• Fixes subset mode to reset to "Replace" when choosing to "Create New" subset. [#1532]

Cubeviz

• Fixed validation message of moment number in moment map plugin. [#1536]

  non-celestial WCS is loaded into Imviz together with another
  extension with celestial WCS. [#1499]
