Apropos the bib module, ConTeXt users wishing to use both the pgf/tikz module (v1.10) and the bib module together, will (currently) have to use the CVS version of pgf because both modules clash with the use of the .aux file. The following was posted by the pgf developer Till Tantau on the pgf maillist: "it turns out that, indeed, the .aux writing of the bib module clashes with pgf's usage of the file of the same name. I renamed this stuff to .pgf and it works fine, now. You will need to get the current CVS of pgf since the change is not quite trivial. Alternatively, a quick-and-easy-fix is to find the file pgf/generic/ pgf/utilities/pgfutil-context.def and to delete the three lines having to do with .aux files at the beginning. Then picture remembering will not work (which it does in the CVS), but that may not be a top priority." I'm assuming the new bib module still uses the .aux file for the same purposes as before.
