Several deprecated items were listed for removal in August, but it's looking likely that 2.060 will come out in August, and I'd prefer not to have them removed for 2.060 given how many items are already in the changelog, and they're already deprecated, so it'll only affect people compiling with -d either way. So, I'm changing the ddoc comments to say September instead of August. They'll be removed in 2.061.
