Release Notes

v5.9.0

⚠️ 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 defualtSeverity: #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)
