Hi, I have just uploaded luatex 0.38.0. This is a beta in the process towards 0.40.0, the version that will be included in texlive 2009. This beta will be shortlived, the plan is to release the next (hopefully last) intermediate beta within a week. What's new: * tex.enableprimitives() had a bug were previously defined (but currently undefined) control sequences prevented the creation of the new csname. * The special calling format callback.register('name', false) not only disables the callback, but also the builtin code it is supposed to replace. * Empty \localleftbox and \localrightbox -es are now suppressed. * Support for <f>.MathConstants.SubscriptShiftDownWithSuperscript was added, to solve the lack of "sub2" in OpenType math. * Luatex now supports horizontal super- and subscript placement corrections via the OpenType MATH mathkern table. See the manual for details. * node.write() no longer copies its argument node list before appending it. * There are six new primitives that are verbose forms of one and two byte special tokens: \Usuperscript \Usubscript \Ustartmath \Ustopmath \Ustartdisplaymath \Ustopdisplaymath * The attribute node leaks in math mode and alignmetns have been fixed. * The 11 simple math noads are now combined into a single "noad" node type. * Static linking against libstdc++ is working once again. * There is a small fix in the keyword scanner to solve the problem of 'Runaway ... while scanning ???' that could happen for some primitives. * Lua now also has the "architecture independent bytecode" patch applied. * Lua is updated to version 5.1.4 with coco patches 1.1.5, and lpeg is now 0.9. * Some TRT/TLT backend bugs are fixed. * Various manual updates. The archives (now including source again) can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ You could also check out the sources via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.38.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco
