I'm now ready to update my version of calibre, which is:
0.4.56
I wish to update to the newest version, without losing any of my ebooks (of course!

) It's been awhile since I updated, as you can see by my version number. But now...I'm ready. Yes, I'm ready.
An enumerated procedure would be appreciated.
Also, do I need to be aware of any problems/issues?
Thanks, everyone.
Don
