Spyder-notebook

Bug Fixes

* Fix compatibility issue which prevented the plugin from working at all if traitlets version 5 is installed ([Issue 314](https://github.com/spyder-ide/spyder-notebook/issues/314), [PR 326](https://github.com/spyder-ide/spyder-notebook/pull/326)).
* Add background to code completions to make them visible ([Issue 318](https://github.com/spyder-ide/spyder-notebook/issues/318), [PR 329](https://github.com/spyder-ide/spyder-notebook/pull/329)).
* Make strings brighter in dark mode to increase legibility ([Issue 319](https://github.com/spyder-ide/spyder-notebook/issues/319), [PR 331](https://github.com/spyder-ide/spyder-notebook/pull/331)).
* Prevent JSONDecodeError when closing notebook ([Issue 317](https://github.com/spyder-ide/spyder-notebook/issues/317), [PR 332](https://github.com/spyder-ide/spyder-notebook/pull/332)).

New Features

* The plugin now uses JupyterLab instead of Jupyter Notebook to render notebooks. This ensures that the new features developed by the Jupyter team, such as drag and drop to reorder code cells, are available in Spyder.
* Support for Python 2 is dropped. The plugin now requires Python 3.5 and Spyder 3.1 or later.
* Notebooks are rendered in a dark theme if Spyder is run using a dark theme.
* A new item, "Server Info", in the option menu of the plugin. This should help with troubleshooting in case of problems.
* Translations for Brazilian Portuguese, German and Spanish are now available.
* When you open Spyder, the plugin will open the notebooks that were open when you last quit Spyder.
