ESLint v5.13.0 released

Highlights

Configuration of globals has been improved with three new options: “off”, “readable”, and “writeable”.

• “off”: Completely disables a global variable that was previously defined.
• “readable”: Equivalent to the old false value, “readable” global variables are in scope but cannot be written to.
• “writeable”: Equivalent to the old true value, “writeable” global variables can be read from and written to.

Configurations using the old true/false values will continue to work, but we encourage you to use the newer, more explicit options.

Check out the documentation on specifying globals for more details!
