Have patience Martin.  I read the news in digest form once a day and just saw
the
announcement and this follow-up a few minutes ago.  I haven't had cause to
download a new
copy of R-devel in the last month so the new Sept 5 version hasn't impacted
me.

The survival package had one line of code that will need modification, which
isn't so bad.
  It involves the scaled Shoenfeld residuals, for which the formula is r V + 1
beta'; r=
matrix of residuals with nvar columns and #deaths rows, V=vcov(fit) = variance
matrix, and
then add beta[j] to each column j.  When the number of covariates is 1 the first
term of
this collapsed to a vector *  1x1 matrix, mostly because of how the code was
written,
which was itself the result of evolution over time.   Bottom line is that I
don't find
either the prior behavior or the new one problematic.
