Backporting for 1.580.3 started

[oliver gondža]

The backporting is on for last 1.580 based LTS.

Scheduled RC date is Dec 24th, I suggest to postpone that by 2 two weeks
to Jan 7th so RC testing will not overlap with holidays.

IIRC Kohsuke accounted for year-end holidays in the 12-week cycle
proposal, by leaving some predetermined dead time at the end of the
year (so there are exactly 4 cycles per year). But I do not recall the
detailed proposal.

Twelve releases per year every four weeks (starting Jan 28 with 1.AAA.1) means we're done on Dec 3 with 1.DDD.3, and four weeks dead time.

The first release for this model was 1.554.1 on Apr 30. While a very quick release, it was still 8 days late in the new model.

After that, new versions were released on average every 30.5 days (6 releases in 183 days instead of 168) until 1.580.2. That one arrived 46 days after 1.580.1, 18 days late.

So while in theory there's a buffer in December, it was quickly used up, resulting in this overlap with holidays.

Backporting is over, we are ready for RC.
