ESLint v3.17.0 released

We just pushed ESLint v3.17.0, which is a minor release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release.

Highlights

Two new rules were added:

• no-compare-neg-zero
• nonblock-statement-body-position

Two new methods were added to the SourceCode API for rules:

• getLocFromIndex and getIndexFromLoc

Two enhancements were made to the RuleTester utility:

• Error message assertions can now be regular expressions.
• output for a test case can be set to null to assert that the case is not autofixed.
