# Change Log for dash-renderer
All notable changes to this project will be documented in this file.
This project adheres to [Semantic Versioning](http://semver.org/).

## [0.9.0] - 2017-09-07
### Fixed
- 🐞 Fixed a bug where Dash would fire updates for each parent of a grandchild node that shared the same grandparent. Originally reported in https://community.plot.ly/t/specifying-dependency-tree-traversal/5080/5
- 🐞 Fixed a bug where the document title that displays "Updating..." wouldn't change if the callback raised an Exception. Now it will be removed on any response, even a failure.

### Added
- 🐌 Experimental behaviour for a customizable "loading state". When a callback is in motion, Dash now appends a `<div class="_dash-loading-callback"/>` to the DOM.
Users can style this element using custom CSS to display loading screen overlays.
This feature is in alpha, we may remove it at any time.

## [0.8.0] - 2017-09-07
### Added
- 🔧 Added support for the `requests_pathname_prefix` config parameter introduced in `dash==0.18.0`

## [0.7.4] - 2017-07-20
### Removed
- Remove unofficial support for `/routes`. This was never officially supported and was an antipattern in Dash. URLs and multi-page apps can be specified natively through the `dash_core_components.Link` and `dash_core_components.Location` components. See [https://plot.ly/dash/urls](https://plot.ly/dash/urls) for more details.

## [0.7.3] - 2017-06-20
### Added
- Added a class `_dash-undo-redo` to the undo/redo toolbar. This allows the undo/redo to be styled (or even removed)
