pypa:pywwt 0.13.0 (2021-09-24)

This is an important release, updating all variations of the pywwt UI ­— the Qt
widget, the ipywidgets widget, and the JupyterLab integration — to use the WWT
“research app”, instead of the old hand-coded HTML/JS wrapper that was specific
to pywwt. This enables us to take advantage of the app's much more sophisticated
UI and robust development framework, and to provide a homogeneous user interface
across these different variations. (#301, #302, @pkgw)

• This release bundles version 0.7.1 of the research app, which includes support
  for many new features, including catalog HiPS datasets, tiled FITS rendering,
  and more.
• Building in the capabilities of this new framework, the WWT widget has gained
  most_recent_source and selected_sources properties that allow code to
  interact with user selections of sources in the UI. Python code can be
  notified of selection actions by using the set_selection_change_callback()
  method. (#311, @Carifio24)
• Also building on the new framework, the WWT widget now knows about HiPS
  progressive catalogs (#308, @imbasimba, @pkgw). You can query available
  catalogs (via the available_hips_catalog_names) property, add them to the UI
  programmatically with wwt.layers.add_hips_catalog_layer, and obtain the data
  currently visible in the WWT view with the layer.refresh() method.
• To support the above, pywwt has started adding asynchronous processing support
  (#308, @pkgw). When pywwt is used inside a Jupyter kernel, the internals of
  the kernel message queue processing are modified to allow "expedited" message
  handling, which is needed to properly support certain pywwt interactive
  functionalities. This hack is relatively self-contained so hopefully it won't
  be too fragile, but time will have to tell.
• The wwt.load_image_collection() method now has a recursive for nested WTML
  files (#308, @imbasimba).
• The WWT widget constructors have a new hide_all_chrome option that hides all
  of the research app’s “chrome” (UI features), to enable a user experience that
  looks similar to the old pre-app style. This mode is the default in the Qt
  widget, so as to preserve the UX of the Glue app.
• Fix pywwt to be able to parse ImageSet XML data even when the ThumbnailUrl
  attribute is missing (#312, @Carifio24).
• Fixes for Astropy 4.3 (#310, @pkgw).
• The type of the wwt.solar_system.scale setting was corrected.
• The Jupyter server was failing to serve files with unguessable content-types;
  this is now fixed.
• Yet more improvements to the CI, test suite, and API documentation.

Tutorial and how-to documentation for all of this new functionality hasn't been
prepared ... yet.
