new RELEASE_NOTES structure for 0.11
merge f36be3db8c8cf419625993be72e4a580bd599501...e46159710500bd7515b134f7203c28c55ee0402b (from 0.11)
new RELEASE_NOTES structure for 1.0 (again, this does not include 0.11.6-dev release notes until they are released. also, no merging is necessary here because release notes are always only for stable versions, so we don't merge any 0.11 release notes fragments until *after* 1.0
better version placeholders :D
