ESLint v5.3.0 released

Highlights

Four new rules have been added:

• no-misleading-character-class reports multi-code-point characters in regular expression character classes. Using these characters in character classes often results in surprising behavior.
• require-atomic-updates reports potential race conditions that result from updating values in async or generator functions.
• no-async-promise-executor reports uses of the Promise constructor that have an async function as the argument. Using an async function in this scenario is not necessary and a potential source of bugs.
• require-unicode-regexp requires all regular expressions to have the u flag. Regular expressions with the u flag have stricter parsing rules and handle unicode text more sensibly, which is useful to avoid unexpected behavior when writing regular expressions.
