ESLint v6.5.0 released

We just pushed ESLint v6.5.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

We have added a new --env-info CLI option, which provides a lot of information that is useful for GitHub issues.
The use-isnan rule supports a new option, enforceForSwitchCase.
The indent rule now supports JSXFragment nodes.

In addition, many rules that removed comments during autofix have been modified to avoid removing comments. Please open an issue if you find any more cases that need to be fixed.
