Hi,
What exactly should I to do with respect to TikZ on the garden (for
the minimals)?
Switch to the version of TikZ and pgfplots from TL 2014 + replace
t-tikz.tex with Hans' version and freeze in that state until TikZ is
fixed upstream?
Or just freeze at whatever version is in CVS at the moment and patch
t-tikz.tex and wait for the patch?
