Dear Guillaume,
thank you for reporting this issue. I apologize that the upgrade
resulted in incompatibilities - this should never happened :-(
Nevertheless, I have a question about the context of the problem... I
have just tried to reproduce the problem using
\documentclass[a4paper]{article}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot file {P.dat};
\end{axis}
\end{tikzpicture}
\end{document}
and the data file with contents
001 001
02 2
3 3
03 03
and it worked without problems (with the most recent versions of pgf and
pgfplots). Furthermore, I am sure that the '\addplot file' processing
did not change (at least not logically).
I can surely assist you, but I fear that I need more input. Can you
confirm that the compilation problem comes from an addplot file? If so,
I would appreciate a minimal working example - and perhaps the .log file
of your attempt to compile it.
Again, let me stress that I understand the burden of using software
which does not work anymore in the way it is expected to be (especially
if it worked earlier). I hope we can find a simple way to restore your
document without changes (even if it might require some sort of patch
from my side).
Best regards
Christian
PS
From what I know without further insight, the interpretation of number
literals as octal base representation has been introduces in pgf in 2008
- it is enabled as soon as one uses the math parser of pgf. I believe
that pgfplots has seen a change in
\addplot coordinates
some time ago: it now uses the math parser. It comes with an option to
disable the math parser, however: try
\pgfplotsset{plot coordinates/math parser=false}
in your preamble.
PS
again a PS: I took the freedom to post a copy of this mail on the
mailing list - perhaps there are other users with a similar problem.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
