    ⚡️ Rule Updates

    • 0️⃣ requireSpaceBeforeKeywords: add a allExcept option for filtering out default keywords (gpiress)
      • This allows you do specify exceptions to the all keywords instead of creating an array of whitelisted keywords when you only want to blacklist a few.

    • requireNumericLiterals: miss if first argument is an Identifier (Robert Jackson)
    • ✅ disallowSpacesInsideTemplateStringPlaceholders: skip the edge case (Oleg Gaidarenko)
