Our team recently discovered (the hard way!) that not all objects in SharePoint 2010 have versioning enabled by default. From what I've discovered, it seems pages, master pages, and page layouts have versioning on by default. Is there a list of what objects are version-controlled by default in SharePoint?
We enabled versioning on the SiteAssets folder after two of us worked on the same CSS file and I accidentally overwrote the file another user had checked in. I had had it open for over a week. Then, carelessly, I said yes to save it when it said there was a newer version on the server.
What objects can be/should be version controlled? How many versions do you keep? Do you do minor/major versions?
Your guidance is appreciated. Thanks.
