## v5.9.1

## :hammer_and_wrench: Bugfixes

-   [bugfix] Removed extraneous deprecation warning produced when using `tslint:recommended` or `tslint:latest` by disabling `typeof-compare` in these rulesets. (#3639)
-   [bugfix] Resolve directories as absolute paths when validating custom `rulesDirectory` paths, which fixes usage with tslint-loader. (#3640)

## v5.9.0

## :warning: Deprecations

-   [deprecation] Several utility functions from `src/language/utils.ts` have been deprecated (#3476)
-   [deprecation] Linting non-existent files now outputs a warning. This will be an error in TSLint 6. (#3313)

## Configuration inheritance changes

Significant changes have been made to configuration inheritance to address a long-standing UX issue around `defaultSeverity`: #2569.

`defaultSeverity` defined in a `tslint.json` file will now override the `defaultSeverity` value defined in any configurations you are extending.
This means that any rules specified in the base configurations can now take on a new `defaultSeverity` if you so choose. If you extend multiple
configuration files, the `defaultSeverity` defined in the last one wins.

In practice, this allows users to, for example, more easily use the built-in TSLint configurations (`tslint:recommended`, `tslint:latest`, `tslint:all`)
and treat all errors as warnings instead of errors.

For more details, see the relevant PRs:

-   Override `defaultSeverity` defined in extended configs (#3449)
-   Inherit defaultSeverity and apply it to preceding base configs (#3530)
