# What’s new in CotEditor 2.3 on Mac

Auto Save and Versions
  CotEditor implemented now the modern document features: Auto Save and Versions. It saves changes automatically as you edit and enable roll-back to the previous versions. Of course, you can still use the classic saving only manually with ⌘S if you want. Choose your favorite way in the General pane.
Various line editing actions
  Move selected lines, remove duplicate lines and more. The various handy line editing actions enable document editing more smoothly and easier.
Auto indent style detection
  No more tab option switching for different source codes. CotEditor detects document’s indent style and sets the corresponding tab expansion behavior automatically for you.
