George pointed out that 4.4 only has 6 months security support here,
which is just me counting wrong I think. It should be March 2017.

Likewise 4.5 followed suite.

Both of them should have been 1 year later. I have updated the wiki.

Meaning it will be earlier later than September 2015.

4.4.3 was released in August which was too soon.

I think it is right to err on the side of stopping later than we said.

Did we stop adding backports to staging-4.4 in September, i.e. is 4.4.4
going to be fixes from August-September + security issues until the release
date?

No, there was active backporting until December (and I expect to at
least put in Andrew's XSA-156 fixup before 4.4.4 goes out, which -
due to the osstest issues - is going to take a little more time anyway).

Done.

I dropped the "EOL - " prefixes, since it seems that if we forget to add
them as new things are EOL'd then there would be ambiguity between things
marked "EOL - Date" and things marked as just "Date" where Date is in the
past -- i.e. folks might think the EOL didn't occur.

Ian.
