Changed

- Fix open redirect vulnerability GHSA-grfj-wjv9-4f9v (CVE-2020-26232)

Added.

- Added a basic, styled `login.html` template. ([220](https://github.com/jupyter/jupyter_server/pull/220), [295](https://github.com/jupyter/jupyter_server/pull/295))
- Added new extension manager API for handling server extensions. ([248](https://github.com/jupyter/jupyter_server/pull/248), [265](https://github.com/jupyter/jupyter_server/pull/265), [275](https://github.com/jupyter/jupyter_server/pull/275), [303](https://github.com/jupyter/jupyter_server/pull/303))
- The favicon and Jupyter logo are now available under jupyter_server's static namespace. ([284](https://github.com/jupyter/jupyter_server/pull/284))

Changed.

- `load_jupyter_server_extension` should be renamed to `_load_jupyter_server_extension` in server extensions. Server now throws a warning when the old name is used. ([213](https://github.com/jupyter/jupyter_server/pull/213))
- Docs for server extensions now recommend using `authenticated` decorator for handlers. ([219](https://github.com/jupyter/jupyter_server/pull/219))
- `_load_jupyter_server_paths` should be renamed to `_load_jupyter_server_points` in server extensions. ([277](https://github.com/jupyter/jupyter_server/pull/277))
- `static_url_prefix` in ExtensionApps is now a configurable trait. ([289](https://github.com/jupyter/jupyter_server/pull/289))
- `extension_name` trait was removed in favor of `name`. ([232](https://github.com/jupyter/jupyter_server/pull/232))
- Dropped support for Python 3.5. ([296](https://github.com/jupyter/jupyter_server/pull/296))
- Made the `config_dir_name` trait configurable in `ConfigManager`. ([297](https://github.com/jupyter/jupyter_server/pull/297))

Removed for now removed features.

- Removed ipykernel as a dependency of jupyter_server. ([255](https://github.com/jupyter/jupyter_server/pull/255))

Fixed for any bug fixes.

- Prevent a re-definition of prometheus metrics if `notebook` package already imports them. ([210](https://github.com/jupyter/jupyter_server/pull/210))
- Fixed `terminals` REST API unit tests that weren't shutting down properly. ([221](https://github.com/jupyter/jupyter_server/pull/221))
- Fixed jupyter_server on Windows for Python \< 3.7. Added patch to handle subprocess cleanup. ([240](https://github.com/jupyter/jupyter_server/pull/240))
- `base_url` was being duplicated when getting a url path from the `ServerApp`. ([280](https://github.com/jupyter/jupyter_server/pull/280))
- Extension URLs are now properly prefixed with `base_url`. Previously, all `static` paths were not. ([285](https://github.com/jupyter/jupyter_server/pull/285))
- Changed ExtensionApp mixin to inherit from `HasTraits`. This broke in traitlets 5.0 ([294](https://github.com/jupyter/jupyter_server/pull/294))
- Replaces `urlparse` with `url_path_join` to prevent URL squashing issues. ([304](https://github.com/jupyter/jupyter_server/pull/304))

Added

- ([191](https://github.com/jupyter/jupyter_server/pull/191)) Async kernel management is now possible using the `AsyncKernelManager` from `jupyter_client`
- ([201](https://github.com/jupyter/jupyter_server/pull/201)) Parameters can now be passed to new terminals created by the `terminals` REST API.

Changed

- ([196](https://github.com/jupyter/jupyter_server/pull/196)) Documentation was rewritten + refactored to use pydata_sphinx_theme.
- ([174](https://github.com/jupyter/jupyter_server/pull/174)) `ExtensionHandler` was changed to an Mixin class, i.e. `ExtensionHandlerMixin`

Removed

- ([194](https://github.com/jupyter/jupyter_server/pull/194)) The bundlerextension entry point was removed.
