What’s Changed

• Support for JupyterLab 2 (#301) Huge thanks to @consideRatio
• BLD: Fix final test install (#296) @gerrymanoim

What’s Changed

• Add license to setup.py (#292) @sergiuser1
• MAINT: Push qgrid to a new npm home (#288) @gerrymanoim
• README item on installing lab extension from source (#289) @itcarroll
• update grid.py for changes in pandas 1.0.1 (#290) @richdevboston

• Readme tweaks
• Compatibility with Jupyter Lab >=1.0.0

• Fixes an issue where the grid widget would flash noticeably when the df attribute or any other attributes were changed. This issue has existed since 1.0. (#186)
• Make the SlickGrid object available via $('.q-grid').data('slickgrid') as suggested here: #178 (comment). This allows you to work with a particular SlickGrid instance from the js console.

• Column options can be provided via the show_grid method. Options can be provided for all columns via the column_options parameter, and for individual columns via the column_definitions parameter.
• Added edit_cell, change_selection, toggle_editable methods for updating the state of an existing grid widget without having to call show_grid.
• Updated the add_row method so that the caller can specify the values for the new row via the row parameter. This will allow people to add rows to a qgrid instance even if it's showing a DataFrame that doesn't have an integer index.
• Updated the remove_row method so that the indices of the rows to remove can optionally be provided via the rows parameter.
• Fixed issue where moving the scroll bar around a bunch of times quickly can cause a series of grid refreshes to occur.
• Thanks to Abigail Hahn (vardaofthevalier) for adding many of the features in the following PR: #191

• Fixes issue where object type columns where not being converted to strings before display when they're an index column
• Fixes issue with displaying unicode strings in python 2 (#200)
• Improves support for viewing DataFrames with a MultiIndex.
  • Cells are merged vertically (similar to how pandas does it) to make it easier to identify the levels of the index.
  • Sorting or grouping any column other than level 0 of the multi-index results in the DataFrame returning to it's normal behavior of never merging cells vertically.
  • Column header is hidden for unnamed levels of the index (instead of showing "level_0", "level_1", etc)

• Fixes issue where editing cells in a DataFrame with an unnamed index results in an error pop up (#198)

• Make categorical column filtering work with old versions of pandas, like 0.18

• Adds new on and off methods at both the module-level (for listening to events on all qgrid instances) and at the instance-level (for listening to events on individual qgrid instances)
• The on and off methods mentioned above should now be used to listen for events instead of listening for the on_value_change event of the _df attribute. In other words using qgrid_widget.observe(on_value_change, names=['_df']) for being notified about changes to the state of the grid (i.e. editing, sorting, filtering) will no longer work.
