We just pushed ESLint v7.0.0, which is a major release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release. This release also has some breaking changes, so please read the following closely.
We want to share with you the significant changes that will be coming in v7.0.0 so you can better prepare for the changes and understand why the changes are necessary.
As part of automating the process of generating rules documentation, ESLint rules now have a new format. We explain the elements of this new format and how you can automatically transform rules from the old format to the new one. If you're a plugin author, it is recommended to update your custom rules accordingly.
In the next minor release of ESLint (which will be 0.7.1 due to us incorrectly pushing 0.6.2 as 0.7.0 last month), there will be a breaking change to the way formatters operate.
In the next version of ESLint, there is a breaking change to remove the capability to use JavaScript files as configuration files. All configuration files must be in JSON format.
