ESLint v5.3.0 released

by Teddy Katz - 3 August 2018

We just pushed ESLint v5.3.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.


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.
