Dash and Dash-Renderer

Added

#1073 Two new functions to simplify usage handling URLs and pathnames: app.get_relative_path & app.trim_relative_path.
These functions are particularly useful for apps deployed on Dash Enterprise where the apps served under a URL prefix (the app name) which is unlike apps served on localhost:8050.
- app.get_relative_path returns a path with the config setting requests_pathname_prefix prefixed. Use app.get_relative_path anywhere you would provide a relative pathname, like dcc.Link(href=app.relative_path('/page-2')) or even as an alternative to app.get_asset_url with e.g. html.Img(src=app.get_relative_path('/assets/logo.png')).
- app.trim_relative_path a path with requests_pathname_prefix and leading & trailing
  slashes stripped from it. Use this function in callbacks that deal with dcc.Location pathname
  routing.
  Example usage:
```
app.layout = html.Div([
    dcc.Location(id='url'),
    html.Div(id='content')
])
@app.callback(Output('content', 'children'), [Input('url', 'pathname')])
def display_content(path):
    page_name = app.strip_relative_path(path)
    if not page_name:  # None or ''
        return html.Div([
            html.Img(src=app.get_relative_path('/assets/logo.png')),
            dcc.Link(href=app.get_relative_path('/page-1')),
            dcc.Link(href=app.get_relative_path('/page-2')),
        ])
    elif page_name == 'page-1':
        return chapters.page_1
    if page_name == "page-2":
        return chapters.page_2
```

Changed

#1035 Simplify our build process.
#1074 Error messages when providing an incorrect property to a component have been improved: they now specify the component type, library, version, and ID (if available).

Fixed

#1037 Fix no_update test to allow copies, such as those stored and retrieved from a cache.

Dash-Core-Components

Added

#711 Added support for dcc.Link (dccLink) and nested dcc.Markdown (dccMarkdown) react components inside of dcc.Markdown
#706
- Added new responsive property that overrides the underlying Plotly.js graph responsiveness from Dash-land
- Added responsiveness on graph parent element resize (previously only worked on window.resize)
- Added new dash-graph--pending class to dcc.Graph, present while resizing, (re-)rendering, loading

Changed

#723 Changed npm package content to allow source code inclusion from other projects
#725 Improve async graph performance by parallelizing resource fetching instead of fetching sequentially
#720 highlight.js is now bundled into the package, and no longer sets the window.hljs variable. Similarly to how plotly.js is handled, it is overridden by a user-provided version if one exists.

Updated

#732
- Upgraded plotly.js to 1.52.1
- Feature release 1.52.0 which contains:
  - Enable loading locale bundles before plotly.js bundles #4453
  - ko localization #4315
- Patch release 1.52.1 containing several bug fixes.
#706
- Upgraded plotly.js to 1.51.3

Dash-Table

Added

#606 Add markdown support for table cells. Cells will be rendered as markdown if the column presentation is specified as markdown.
- Add highlight.js for syntax highlighting. If window.hljs is specified, that will be used for highlighting instead.

Fixed

#670 Fix a bug where derived_filter_query_structure was not getting updated properly
#677 Fix a bug where the table fails to load when used inside an iframe with a sandbox attribute that only has allow-scripts
#665 Fix a bug in Firefox where the dropdown cells height is incorrect
