v0.19.0

• Update internal rust-analyzer
• jupyter: Ensure iopub idle isn't sent before stdout output
• Add support for shell commands (thanks wiseaidev and drendog)
• User code is now compiled with rust 2024 edition
• MSRV is now 1.85

v0.17.0

• Reverted to static linking by default as we had prior to 0.16.0. You can still get dynamic linking
  by setting :allow_static_linking 0 which is recommended if it works for you. Forcing dynamic
  linking was breaking in hard-to-debug ways for several people on both Mac and Linux.
• Fixes for async-await support.
• Added commands to set runtime environment variables (:env) and build environment variables
  (:build_env).
• An evcxr.toml in your startup directory can now be used to override your target-dir. Thanks
  baiguoname.
• Added support for selecting rustc's codegen backend. You can now use the cranelift backend by
  doing :toolchain nightly then :codegen_backend cranelift.
• Updated rust-analyzer
• Minimum rust version is now 1.74 due to changes in rust-analyzer

v0.16.0

• 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

v0.15.1

• Fix miscompilation when there's a trailing comment after an expression.
• Fix out-of-order printing in evcxr_jupyter

v0.15.0

• :dep now prints "Compiling" messages emitted by Cargo to show progress. Thanks d86leader and
  adiSuper94.
• :type (or :t) command added to get the type of a single variable. Thanks d86leader.
• :types command added to enable the display of evaluated expression types.
• Attributes (e.g. #[derive(Debug)]) now cause REPL to wait for an additional line. Thanks
  Marcono1234.
• Fixed :toolchain command that was broken in a previous release.
• Suggest offline mode when adding a dependency fails. Thanks Marcono1234.
• Added links to some new resources for the Jupyter kernel. Thanks wiseaidev.
• Escape paths - especially important for use on Windows. Thanks Marcono1234.
• Fix for a file locking issue on Windows.
• Documentation fixes. Thanks Marcono1234.
• init.evcxr is now executed all at once rather than a line at a time.
• Try to use cargo/rustc paths from build time if cargo/rustc aren't on the path at runtime.
• Minimum supported rust version is now 1.67.0.
• Arguments after -- are now available via std::env::args in the REPL.
• CLA no longer required for contributions.
• Repository moved out of Google org into its own "evcxr" org.
• License changed to dual Apache2/MIT (Previously just Apache2).

v0.14.2

• Fixed jupyter kernel running from vscode. Thanks TethysSvensson for bisecting
  the cause.
• Updated rust-analyzer

v0.14.1

• Fixed thread starvation in Jupyter integration on systems with few CPUs.
• Support interrupting execution in Jupyter notebook. Process gets terminated,
  so variables are lost, but other state is preserved.
• Support interrupting execution in REPL by pressing ctrl-c.
• Updated rust-analyzer.

v0.14.0

• :dep lines can now be commented out without breaking subsequent :dep
  lines. Thanks JohnScience!
• Reduced interleaving of stdout and stderr.
• Errors now render using ariadne, giving a much nicer presentation. Thanks
  HKalbasi!
• Small speedup in execution time by bypassing rustup.
• preserve_vars_on_panic is now true by default (as it used to be). It now
  works much better than before, with all variables being preserved if a panic
  occurs.
• By using rustyline's new external printer API, stderr output that hasn't been
  displayed before we return to the prompt no longer messes up the prompt. In
  fact, you can now spawn a thread that writes to stderr in the background and
  the output now appears above your prompt.
• Jupyter kernel now uses a native Rust library for ZMQ, so no longer requires
  cmake to build.
• The last bit of code that tried to use rustc error messages to determine
  variable types has been deleted. Now if rust-analyzer can't determine the type
  of a variable, we ask the user to add an explicit type annotation.
• Update rust-analyzer
• Building evcxr now requires rust 1.63 or higher.
• Added a release workflow so that binaries for the latest Linux (built on
  Ubuntu), Windows and Mac are available for download on the releases page.
