• Now compiles dependencies as dylibs. This means that mutable static variables in dependencies are
  now preserved between executions. If you hit problems with this, please file a bug report. You can
  restore the old behaviour with :allow_static_linking 1.
• New built-in caching mechanism. Enable a 500MiB cache by adding :cache 500 to your
  ~/.config/evcxr/init.evcxr.
• Use of sccache is now deprecated, since it doesn't work with dylibs. Switching to the new caching
  mechanism is recommended.
• Update to latest rust-analyzer
• New command to show current dependencies: :show_deps. Thanks momori256.
• Fixed some issues with the jupyter kernel not shutting down cleanly.
• Fixed Tokio runtime being poisoned after panic. Thanks martinitus.
• Added a :doc command to show documentation for something. Thanks baiguoname.
• Improvements to an error message. Thanks baiguoname.
• Improved docs for how to determine config path. Thanks anandijain.
• Now requires rust version 1.70 or later
