Dash v1.21.0

on GitHub

Dash and Dash Renderer

Added

• #1675 Add new Dash constructor argument extra_hot_reload_paths. This allows you to re-initialize the Python code of the app when non-Python files change, if you know that these files impact the app.

Changed

• #1675 Remove the constraint that requests_pathname_prefix ends with routes_pathname_prefix. When you are serving your app behind a reverse proxy that rewrites URLs that constraint needs to be violated.
• #1611 and #1685 Package dash-renderer artifacts and dependencies with Dash, and source renderer resources from within Dash.
• #1567 Julia component generator puts components into src/jl - fixes an issue on case-insensitive filesystems when the component name and module name match (modulo case) and no prefix is used. Also reduces JS/Julia clutter in the overloaded src directory.

Fixed

• #1664 Fix #1649, makes the devtools readable with a dark theme.
• #1640 Fix #1475, missing timing_information after certain modifications to Flask behavior

Dash Core Components

Fixed

• #963 Fixes #885

  This applies the fix from #878 to the RangeSlider.
  It not only fixes the bug where the tooltips were visible when slider was not, but it also reduces the lag in the
  tooltip when the slider handles are moved.

Updated

• #939 Upgrade Plotly.js to v2.2.1. Note that this is a major version upgrade to Plotly.js, however we are not treating this as a breaking change for DCC as the majority of breaking changes in Plotly.js do not affect the Dash API. The one exception is that several trace types that have long been deprecated are removed entirely.
  • Major release 2.0.0:
    • Stop exporting d3 as Plotly.d3, and remove many other deep pieces of the public API. This does not affect the dcc.Graph component, but if you make use of Plotly from the global scope in some other way you may be affected.
    • Drop the deprecated trace types contourgl and area, as well as legacy pre-scatterpolar polar attributes bar.r, bar.t, scatter.r, scatter.t, layout.radialaxis, layout.angularaxis. Use scatterpolar, barpolar, and polar subplots instead.
    • heatmapgl and pointcloud trace types, and the transform attribute are deprecated, and will be removed in a future release.
    • Increase CSP safety by removing function constructors. 3D plots still use function constructors, but if you place one of the non-3D bundles (including the new strict bundle) in your assets folder you will have no function constructors.
    • Remove "Aa" text in legends.
    • Default hovermode to "closest".
    • Default textposition to "auto" in bar traces. If you previously used the bar.text attribute for hover only, you will need to explicitly set textposition="none".
    • Add bar.marker.pattern, image.zsmooth, and various other features and bugfixes.
  • Feature release 2.1.0:
    • New icicle trace type.
    • New legendrank trace attribute.
    • Several other additions and bug fixes.
  • Feature release 2.2.0:
    • Legend group titles
    • Half-year directive (%h) for date formatting
    • Several other bug fixes and performance improvements
  • Patch release 2.2.1 containing a security fix.

Added

• #932 Adds a new copy to clipboard component.
• #948] Adds disabled_days prop to DatePickerRange and DatePickerSingle components. With this prop you can specify days that should be made unselectable in the date picker, in addition to those that fall outside of the range specified by min_date_allowed and max_date_allowed.

Changed

• #972 Updated R package vignettes and dash-info.yaml to regenerate examples without attaching now-deprecated core component packages (dashHtmlComponents, dashCoreComponents, or dashTable).

Dash HTML Components

Changed

• #194 Updated dependencies and build process
• #190 Updated R package vignettes and dash-info.yaml to regenerate examples without attaching now-deprecated core component packages (dashHtmlComponents, dashCoreComponents, or dashTable).

Dash Table

Fixed

• #907
  • Fix a bug where pagination did not work or was not visible. #834
  • Fix a bug where if you are on a page that no longer exists after the data is updated, no data is displayed. #892

Added

• #916

  • Added html option to markdown_options prop. This enables the use of html tags in markdown text.

• #545

  • Case insensitive filtering
  • New props: filter_options - to control case of all filters, columns.filter_options - to control filter case for each column
  • New operators: i=, ieq, i>=, ige, i>, igt, i<=, ile, i<, ilt, i!=, ine, icontains - for case-insensitive filtering, s=, seq, s>=, sge, s>, sgt, s<=, sle, s<, slt, s!=, sne, scontains - to force case-sensitive filtering on case-insensitive columns

Changed

• #918 Updated all dependencies. In particular the highlight.js upgrade changes code highlighting in markdown: we have long used their "github" style, this has been updated to more closely match current github styles.
• #901 Updated R package dash-info.yaml to regenerate example without attaching now-deprecated core component packages (dashHtmlComponents, dashCoreComponents, or dashTable).
