Hi JC,
By default any image you work on gets a small icon placed in the corner of the image, LR saves a sidecar file automatically of the modifications you've made, no need to do a save per say, any time you return to an image and re-enter the develop module your right back to where you left off, nothing is set in stone until you export your file as a .jpg or other format. I hope this helps and good luck with your PP, and keep shooting...
In Lightroom, you have to set the catalog preferences to write changes to xmp. The default state is to only keep edits in the preview database and NOT write them to xmp.
Changes made to a raw file are never set in stone. Exporting an image merely takes a snapshot of your current edits and commits them to a bitmap file. The original edits can still be undone, fine tuned, or you can even make virtual copies and reset the image to it's unedited state to do a different treatment - high-key, split toning, monochrome, etc.
