v0.2.0 - 2022/02/10

Added

• cache_selection=True allows to retrieve the checkbox state when re-displaying a grid,
  as long as they have the same name. Fixes #22
• prerender=False moves the rendering of molecule images from Python to the browser and
  only when the molecule is on the current page, giving a performance boost and allowing
  to process much larger files. Fixes #17
• substruct_highlight=True highlight the atoms that matched the substructure query when
  using the SMARTS search (only available when prerender=False). Fixes #18
• Added CSV save option. Exports all the data present in subset and tooltip for the
  current selection
• Support for .sdf.gz files
• Added automated tests of the interface, which should prevent future updates from
  breaking things

Changed

• Python 3.6 is no longer supported
• Molecule images are now generated by the web browser (see prerender=False argument)
• The coordinates of the input file are now ignored by default (use_coords=False). This
  change was made to comply with generating images from SMILES string with the browser by
  default.
• Python callbacks are now automatically registered in Google Colab
• Javascript callbacks can access RDKit as either RDKit or RDKitModule
• The "img" field is now available from the callback data
• The subset parameter now throws an error if "img" is not present
• Clicking "Check all"/"Uncheck all" should now be faster
• Bumped RDKit JS version to 2021.9.4 to better support moldrawoptions
• Installation now requires jinja2>=2.11.0 to prevent an error when given a pathlib.Path
  object instead of a string

Fixed

• Callbacks now work when selection=False. Fixes: Issue #22
• Using both transform and style should now display the labels as expected in the
  tooltip
• Fixed a race condition when clicking checkboxes on different grids
• Fixed the gap argument not being properly taken into account
• Automatic resizing of the iframe (used in mols2Grid.display) should now work even
  better
