 Spreadsheet Architect lets you turn any activerecord relation or plain ruby class object into a XLSX, ODS, or CSV spreadsheets. Generates columns from model activerecord column_names or from an array of ruby methods.
 
 Spreadsheet Architect adds the following methods to your class:

 Post.order(name: :asc).where(published: true).to_csv
 ```
 
+## Note: Breaking Changes in 1.1.0
+The `spreadseheet_columns` method has been moved from the class to the instance. So now you can use string interpolation in your values. Please re-read the Model section below to see the changes. The side effect of this is if you are using the spreadsheet_columns option directly on the .to_* methods.
