Release 4.2 adds a new API for enabling and installing extensions. Extensions can now be enabled at the system-level, rather than just per-user. An API is defined for installing directly from a Python package, as well.

Highlighted changes:

• Upgrade MathJax to 2.6 to fix vertical-bar appearing on some equations.
• Restore ability for notebook directory to be root (4.1 regression)
• Large outputs are now throttled, reducing the ability of output floods to kill the browser.
• Fix the notebook ignoring cell executions while a kernel is starting by queueing the messages.
• Fix handling of url prefixes (e.g. JupyterHub) in terminal and edit pages.
• Support nested SVGs in output.

And various other fixes and improvements.

4.1.0

Bug fixes:

• Properly reap zombie subprocesses
• Fix cross-origin problems
• Fix double-escaping of the base URL prefix
• Handle invalid unicode filenames more gracefully
• Fix ANSI color-processing
• Send keepalive messages for web terminals
• Fix bugs in the notebook tour

UI changes:

• Moved the cell toolbar selector into the View menu. Added a button that triggers a "hint" animation to the main toolbar so users can find the new location. (Click here to see a screencast )

  

• Added Restart & Run All to the Kernel menu. Users can also bind it to a keyboard shortcut on action restart-kernel-and-run-all-cells.

• Added multiple-cell selection. Users press Shift-Up/Down or Shift-K/J to extend selection in command mode. Various actions such as cut/copy/paste, execute, and cell type conversions apply to all selected cells.

  

• Added a command palette for executing Jupyter actions by name. Users press Cmd/Ctrl-Shift-P or click the new command palette icon on the toolbar.

  

• Added a Find and Replace dialog to the Edit menu. Users can also press F in command mode to show the dialog.

  

Other improvements:

• Custom KernelManager methods can be Tornado coroutines, allowing async operations.
• Make clearing output optional when rewriting input with set_next_input(replace=True).
• Added support for TLS client authentication via --NotebookApp.client-ca.
• Added tags to jupyter/notebook releases on DockerHub. latest continues to track the master branch.
