Back in April we released cookstyle 0.0.1 as an experiment to bundle the .rubocop.yml file we had been using in community cookbooks with a pre-determined Rubocop release. Since then it’s turned out quite well and today I’m excited to announce that we’ve released cookstyle 1.0. Why 1.0? First there are breaking changes in this release as we’ve upgraded from Rubocop 0.39 -\> 0.46 and enabled new cops. Second we think Cookstyle is ready for primetime and we want to make sure any users that want to pin versions according to SemVer can.

Here’s a summary of the new cops that were introduced with this release:

**Newly disabled Cops:**  
Metrics/CyclomaticComplexity  
Style/NumericLiterals  
Style/RegexpLiteral in /tests/ directory  
Style/AsciiComments

**Newly Enabled Cops** :  
Bundler/DuplicatedGem  
Style/SpaceInsideArrayPercentLiteral  
Style/NumericPredicate  
Style/EmptyCaseCondition  
Style/EachForSimpleLoop  
Style/PreferredHashMethods  
Lint/UnifiedInteger  
Lint/ShadowedException  
Lint/PercentSymbolArray  
Lint/PercentStringArray  
Lint/EmptyWhen  
Lint/EmptyExpression  
Lint/DuplicateCaseCondition  
Style/TrailingCommaInLiteral
