Dash and Dash Renderer

Added

• #1493 Fix #1143, a bug where having a file with one of several common names (test.py, code.py, org.py, etc) that imports a dash component package would make import dash fail with a cryptic error message asking whether you have a file named "dash.py"

Dash v1.16.1

Dash and Dash-Renderer

Changed

• #1376 Extends the getTransform logic in the renderer to handle persistenceTransforms for both nested and non-nested persisted props. This was used to to fix dcc#700 in conjunction with dcc#854 by using persistenceTransforms to strip the time part of the datetime so that datepickers can persist when defined in callbacks.

Fixed

• #1408 Fixes a bug where the callback graph layout would reset whenever a callback fired, losing user-initiated layout changes (#1402) or creating a new force layout (#1401)

Dash-Core-Components

Fixed

• #854 Used persistenceTransforms to strip the time part of the datetime in the persited props of DatePickerSingle (date) and DatePickerRange (end_date, start_date), fixing dcc#700.

Added

• #850 Add property prependData to Graph to support Plotly.prependTraces
  • refactored the existing extendTraces API to be a single mergeTraces API that can handle both prepend as well as extend.

Dash v1.16.0

Dash and Dash-Renderer

Added

• #1371 You can now get CSP script-src hashes of all added inline scripts by calling app.csp_hashes() (both Dash internal inline scripts, and those added with app.clientside_callback) .

Changed

• #1385 Closes #1350 and fixes a previously undefined callback behavior when multiple elements are stacked on top of one another and their n_clicks props are used as inputs of the same callback. The callback will now trigger once with all the triggered n_clicks props changes.
• #1179 New and improved callback graph in the debug menu. Now based on Cytoscape for much more interactivity, plus callback profiling including number of calls, fine-grained time information, bytes sent and received, and more. You can even add custom timing information on the server with callback_context.record_timing(name, seconds)

Fixed

• #1384 Fixed a bug introduced by #1180 breaking use of prevent_initial_call as a positional arg in callback definitions

Dash-Core-Components

Updated

Dash v1.15.0

Dash and Dash Renderer

Added

• #1355 Removed redundant log message and consolidated logger initialization. You can now control the log level - for example suppress informational messages from Dash with app.logger.setLevel(logging.WARNING).
• #1253, #1377 Added experimental --jl-prefix option to dash-generate-components, optionally generates Julia version of components and corresponding Julia package

Changed

• #1180 and #1375 Input, Output, and State in callback definitions don't need to be in lists. You still need to provide Output items first, then Input items, then State, and the list form is still supported. In particular, if you want to return a single output item wrapped in a length-1 list, you should still wrap the Output in a list. This can be useful for procedurally-generated callbacks.
• #1368 Updated pytest to v6.0.1. To avoid deprecation warnings, this also updated pytest-sugar to 0.9.4 and pytest-mock to 3.2.0. The pytest-mock update only effects python >= 3.0. Pytest-mock remains pinned at 2.0.0 for python == 2.7.
