We have been doing the minor release of series 5 and 6 on the same
date which is 10th of every month. Doing both on the same day is a lot
of work together. To make it easier, we are going to have the series 6
release on 30th of every month.
Note: 5 is on 10th and 4.1 is on 20th and once we have 7, we will end
of life 4.1 and do 7 on 20th.
