Perpetuity v0.4 Release Notes

    • Mapper select DSL now more closely resembles Enumerable syntax
      • Instead of mapper.select { published_at < Time.now } you would write mapper.select { |article| article.published_at < Time.now }
      • It's a little more typing, but it eliminates a lot of problems that came from calling instance_exec on the block. It meant we couldn't call methods on the current object (they would be invoked on the Query object) or use instance variables from the current object.
      • Explained more in issue #19
