13.0.0 (2021-11-18)
Whilst this is a major release of the packages, in this case the major version change is primarily there to signify alignment with v13 of Angular.
You should look to migrate to v13 of all Angular packages, as well as v8 of eslint and v5 of typescript-eslint.
All of this will be handled for you automatically if you leverage the ng update schematics provided by @angular-eslint. You can simply include @angular-eslint/schematics in your ng update command alongside @angular/cli and @angular/core, for example:
npx ng update @angular/cli @angular/core @angular-eslint/schematics
