Actually only maximum of 4, but still a lot.

Makes sense, no "old old stable" anymore. :)

According to our experience with 4.5 LTS and the expectation rised in
this thread I split up this maintainance of the LTS in two periods:

* 2 years of full support (bugfixes / backported bugfixes + security).
* 1 year of security fixes and "browser fixes" (making sure the LTS
still works on current browser technologies): no more backported fixes
other kind of fixes.

Actually we are almost reaching this kind of first phase "stability"
with 4.5, as I feel it.

I would not include "6.3" in any schedule yet.

An important question rised in this thread and not answered by the
initial proposal is: when will the new LTS be released?

6.2 could be a candidate (Oct/2013), but the argument of little overlap
(6 months) with the current 4.5 LTS maintainance can be important. On
the other hand we would have more time to focus on "getting the 6.x
branch" rocket stable and even more in line with the TYPO3 Neos / Flow

6.1 could be a candidate (Apr/2013), which would fit quite well in the
maintainence strategy for for LTS: As soon as a new LTS is released, the
old LTS goes into "old-LTS-mode" (only sec+important fixes) for a
further year (of overlap).

Regardless if the LTS is 6.1 or 6.2, starting Oct/2013 we will only be
maintaining 3 releases at a time.

Considering that 6.1 development will start very soon, a decision needs
to be made at that time (together with the new release manager...). :)
