An in-range update of tslint is breaking the build 🚨

Version 5.4.0 of tslint just got published.

Branch	Build failing 🚨
Dependency	tslint
Current Version	5.3.2
Type	devDependency

This version is covered by your current version range and after updating it in your project the build failed.

As tslint is “only” a devDependency of this project it might not break production or downstream projects, but “only” your build or test tools – preventing new deploys or publishes.

I recommend you give this issue a high priority. I’m sure you can resolve this :muscle:

Status Details

- ❌ **continuous-integration/travis-ci/push** The Travis CI build failed [Details](https://travis-ci.org/types/npm-source-map-support/builds/238213273?utm_source=github_status&utm_medium=notification)

Release Notes

v5.4.0

⭐️ Non-breaking API changes

The --type-check CLI option now only enables checking for compiler errors before linting. It is no longer required to enable rules that use the type checker -- only need to supply --project now.

🎉 New rules, options, and fixers

[new-rule] use-default-type-parameter (#2253)

Version 5.9.0 just got published.

Your tests are passing again with this version. Explicitly upgrade to this version 🚀

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)
