[Releasing] FW: [Development] Schedule for Qt 4.8.1

[Salovaara Akseli]

Hi,

Just noticed that conversation about Qt 4.8 release plan \ schedule is ongoing on development mailing list.  
How the schedule looks for releasing mailing list participant's point of view?  Comments, ideas, opinions?
For me at least preliminary schedule looks promising.

Br,
Akseli

Excellent. As it is a patch release, I think it will be just fine that
everybody knows the timing, and can handle the fixes accordingly.

For the patch releases there always needs to be the capability to issue
one quickly in case something urgent comes up (like a serious security
issue).

Having the patch releases strictly tied into some intervals, or amount of
fixes does not work well in my opinion. But I do agree that some criteria
should be agreed upon, so that it is easy to know when the time is right
for a release.

Then it should also be noted that 4.8 is a bit of a special case as the
last of the Qt 4 series. It needs a more patch releases than I think will
be needed for Qt 5 (with regular 6 months for the minor releases it should
be very easy to migrate between these).

I think good timing for the 4.8 patch releases would the roughly:

4.8.1 in mid-March 
4.8.2 in end-May
4.8.3 in end-September
4.8.3 in mid-January 2013

Which leads to about 3 month intervals, that should be suitable for
increasing the stability of this already mature base.

As said, we need to also see what makes sense content wise, and be
prepared for a quick release if something urgent comes up.

I am very happy to hear your feedback and thoughts on this. After the
discussion it would be good to update the wiki with jointly agreed release
plan for 4.8.

Yours,

		Tuukka
