+
+ TexImg standard preamble changed
+
+ The teximg plugin now has a configurable LaTeX preamble.
+ As part of this change the `mchem` LaTeX package has been removed from
+ the default LaTeX preamble as it wasn't included in many TeX installations.
+
+ The previous behaviour can be restored by adding the following to your
+ ikiwiki setup:
+
+ teximg_prefix => '\documentclass{scrartcl}
+ \usepackage[version=3]{mhchem}
+ \usepackage{amsmath}
+ \usepackage{amsfonts}
+ \usepackage{amssymb}
+ \pagestyle{empty}
+ \begin{document}',
+
+ In addition, the rendering mechanism has been changed to use `dvipng` by
+ default, if available.

ikiwiki (2.60) unstable; urgency=low
Admin preferences are moving from the web interface to the setup file.
* ikiwiki-makerepo: Added support for monotone. (Thomas Keller)
* map: The fix for #449285 was buggy and broke display of parents in certian
circumstances.
+ * teximg: The prefix is configurable, and has changed to not include the
+ nonstandard mhchem by default. (willu)
+ * teximg: dvipng is used if available to render images. Its output is
+ antialiased and better than dvips. If not available, the old dvips+convert
+ chain will be used. (willu)
+ * Drop suggests on texlive-science, add suggests on dvipng.

+## configuration
+
+There are several configuration directives that can be used in the setup
+file. `teximg_prefix` can be set to change the LaTeX preamble, and
+`teximg_postfix` to change the LaTeX postfix. The `teximg_dvipng` setting
+can be set to 0 to disable use of `dvipng`, and instead force use of `dvips`
+and `convert`.
