- update to version 5.7.7:
  * Fix regression in restarting kernels in 5.7.5. The restart handler
    would return before restart was completed.
  * Further improve compatibility with tornado 6 with improved checks
    for when websockets are closed.
  * Fix regression in 5.7.6 on Windows where .js files could have the
    wrong mime-type.
  * Fix Open Redirect vulnerability where certain malicious URLs could
    redirect from the Jupyter login page to a malicious site after a
    successful login. A CVE has been requested for this vulnerability.
- update to version 5.7.6:
  * 5.7.6 contains a security fix for a cross-site inclusion (XSSI)
    vulnerability, where files at a known URL could be included in a
    page from an unauthorized website if the user is logged into a
    Jupyter server. The fix involves setting the
    X-Content-Type-Options: nosniff header, and applying CSRF checks
    previously on all non-GET API requests to GET requests to API
    endpoints and the /files/ endpoint.
    The attacking page is able to access some contents of files when
    using Internet Explorer through script errors, but this has not
    been demonstrated with other browsers. A CVE has been requested
    for this vulnerability.
- update to version 5.7.5:
  * Fix compatibility with tornado 6 (:ghpull:`4392`, :ghpull:`4449`).
  * Fix opening integer filedescriptor during startup on Python 2
    (:ghpull:`4349`)
  * Fix compatibility with asynchronous KernelManager.restart_kernel
    methods (:ghpull:`4412`)
- Update requirements: python-jupyter_core >= 4.4.0, python-terminado >= 0.8.1.
- Fix {name} -> %{name}
- Update to 5.7.4
  * fixes a bug introduced in 5.7.3, in which the ``list_running_servers()``
    function attempts to parse HTML files as JSON, and consequently crashes
   (:ghpull:`4284`).
- Update to 5.7.3
  * Launch the browser with a local file which redirects to the server address
    including the authentication token (:ghpull:`4260`).
    This prevents another logged-in user from stealing the token from command line
    arguments and authenticating to the server.
    The single-use token previously used to mitigate this has been removed.
    Thanks to Dr. Owain Kenway for suggesting the local file approach.
  * Upgrade bootstrap to 3.4, fixing an XSS vulnerability, which has been
    assigned `CVE-2018-14041 <https://nvd.nist.gov/vuln/detail/CVE-2018-14041>`_
    (:ghpull:`4271`).

    from being able to execute javascript. CVE request pending.

    executing javascript with access to the server API. CVE request
    pending.

      type conversions apply to all selected cells.

      name. Users press ``Cmd/Ctrl-Shift-P`` or click the new
      command palette icon on the toolbar.
