JSHint 2.11.0

2.11.0 (2020-01-13)

This release was previously published using the "release candidate" pattern. No
regressions were reported in the four weeks that followed, so the change set is
being promoted to a true "minor" release.

The release notes for version 2.11.0-rc1 completely describes the changes
included in this version.

JSHint 2.10.0

2.10.0 (2019-02-05)

This release introduces support for the three most recent editions of
JavaScript: ES7, ES8, and ES9. Users can enable support for any one of these
via the esversion linting option.

Perhaps most notably, this includes "async functions." Since their
standardization in ES2017, no feature has been more requested. We're happy to
add support for this powerful new language feature. If the delay is any
indication, extending JSHint's parser was no small task, and we were able to
make many seemingly-unrelated corrections along the way.

That progress is easiest to see in JSHint's performance on Test262 (the
official test suite for the JavaScript programming language). Version 2.9.6
passed 84% of those tests. Version 2.10.0 passes 96%. We're excited to push
that number higher, especially considering that new language features and new
tests are being added every day. If you're curious about what needs to be done,
we maintain an "expectations file" describing every test JSHint is known to
fail today.

This release also includes brand-new parsing logic for classes. We thank Ethan
Dorta and Alex Kritchevsky, the two first-time contributors who made this
possible!
