## What's happening?

• #### Error messages hard to catch in plain TeX/ConTeXt

TeX does not pause in the event of an error in plain or ConTeXt because \PackageError is defined using an \immediate\write17 instead of an \errmessage in pgfutil-{plain,context}.tex.

• #### ConTeXt and ampersand

In ConTeXt MkIV, the active ampersand does not get assigned the correct value in a "matrix of math nodes." In the example below, the first "\show &" shows the value of \pgfmatrixnextcell as expected, while in the second case the contents of & is "&" \usemodule[tikz] \usetikzlibrary[matrix] \starttext \starttikzpicture \matrix[matrix of...

• #### pow broken for non-integer bases and exponents

Example: \documentclass{article} \usepackage{amsmath,tikz} \begin{document} \parindent=0em \pgfmathsetmacro\result{pow(0.5,1.5)} $(\tfrac12)^{3/2}\ne\result=2\sqrt2$\\ \pgfmathsetmacro\result{pow(0.5,0.5)} $(\tfrac12)^{1/2}\ne\result=\sqrt2?$\\ \pgfmathsetmacro\result{pow(0.5,-1.5)} $(\tfrac12)^{-3/2}\ne\result=2\sqrt2$\\ \pgfmathsetmacro\result{pow(0.5,-0.5)}...

• #### Auto label placement and curved paths

Combining the 'bend right' option and 'auto' label placement gives me strange results when applied to somewhat short paths. In the attached example, notice that the dots appear in the wrong order. If the distance of A and B is increased, or the 'auto' option removed, then one gets the expected result. \documentclass{article} \usepackage{tikz} \begin{document}...
