Draft NOTES for 1.13.0

@mglukhovsky can you please review?

@danielmewes @Tryneus @mlucy @danielmewes @neumino @srh Please also take a look to make sure I haven't mis-characterized some of your fixes.
Additional documentation on why this was removed, or what users should use instead, or a link to an alternate API command's documentation to read would be good here.
