  • ➕ Added:

    • 🚦 When a subprocess exits with a signal (e.g. SIGSEGV), a message is printed, similar to Bash.
    • ➕ Added comma literals to subproc mode.
    • @$(cmd) has been added as a subprocess-mode operator, which replaces in the subprocess command itself with the result of running cmd.
    • 🆕 New showcmd alias for displaying how xonsh interprets subprocess mode commands and arguments.
    • Added $DYNAMIC_CWD_WIDTH to allow the adjusting of the current working directory width in the prompt.
    • ➕ Added $XONSH_DEBUG environment variable to help with debugging.
    • The ${...} shortcut for __xonsh_env__ now returns appropriate completion options

    🔄 Changed:

    • 🏁 On Windows the default bash completions files $BASH_COMPLETIONS now points to the default location of the completions files used by 'Git for Windows'
    • On Cygwin, some tweaks are applied to foreign shell subprocess calls and the readline import, in order to avoid hangs on launch.
