November releases: 30.0.2, 29.0.9 and 28.0.12

There was a reason the 29.0.9 is not distributed currently:

29.0.9 pulled from download servers

Due to a regression in the PDF viewer we had to pull NC 29.0.9 from the download server. Updates to this version are not proposed anymore (but to 30 instead). We will follow up with the regular 29.0.10 next week, along other maintenance releases. RC1s can be expected this Thursday.
