Did Apple get rid of autosave and versions in Mavericks?
Versions is not in Finder's context menu in Mavericks and later. Apple recommends the use of the File menu to access versions of files.


  Browse, restore, duplicate, and delete versions
  
  
  Open the document, then choose File > Revert To > Browse All Versions.
  Click tick marks along the timeline to browse versions.
  Display the version you want, then do one of the following:
  
  
  To restore your document to this version, click Restore.
  To duplicate this version in a new document, press the Option key and click “Restore a Copy.”
  To leave your document as is, without changes, click Done.

Documents can be reverted again using the File menu.


  Revert a document to the last opened version
  
  Choose File > Revert To, then choose Last Opened, Last Saved, or Previous Save.

Access to versions through the disclosure triangle icon next to the name of the document in the title bar is also gone—again, the File menu is preferred.
