To upgrade from 1.3.11sr6 to 1.3.11sr7-1, you need two files:
this and
this.
There is no complete tarball for 1.3.11sr7-1 since the later updates were only released when 1.4.0 was already the current version. If - for whatever reason - you wanted to do a fresh install of 1.3.11, then grab the
last complete tarball and apply the
combo update.
(Of course I would strongly advise against starting a new site with 1.3.11 now. Support for 1.3.11 will end when 1.4.1 is released.)
