This change was planned for 0.40.0, + but *now* is the time to test it. + +* A bugfix for \primitive in various expandable contexts, + and \primitive now generates an error message when the + argument is not actually a primitive's name. + +* There was a bug found in the math accent handling. + +* Large math operators are now treated like extensible characters + in the sense that they can be composed of segments. + +* The extra assign- and restore tracing information from eTeX + had a massive bug because of a dangling else in the pascal web. + As a side-effect of fixing this bugs, all such potential errors + in the pascal web have been fixed (for now). + +* The math parameters can now be set and queried from lua code + via the new tex.setmath() and tex.getmath() functions. + +* Reflection in a \hbox was broken. + +* There was a leak of direction nodes in the paragraph builder. + +* The font backend now does a small peek to differentiate + truetype and postscript style opentype fonts. This fixes + the "Can't find CFF table" bug for otf's with truetype outlines. + +* Parameters and registers can now also be assinged to globally + from lua (see the manual for details). + +* It is now possible to query the current math style while a + formula is still being constructed by using the new read-only + value \mathstyle. Associated is the new command \Ustack that + is to be used as a prefix for {.. \over ..} and friends. + See the manual for more information. + +* The embedded MPLib is brought up to date with the current + metapost repository (version 1.110 and a few small patches). + +* Luatex can now handle two breakpoints inside a single ligature + (like for the functional word of-f-ice). The solution is not + perfect yet, but the chance of missed hyphenation points in + actual documents should now be negligible. + +* Some speedups in the font loading code, and in the handling of + pdf_literal nodes that are set from within Lua code. + +* Some source code and manual cleanup, as usual. + +============================================================== +Luatex beta-0.38.0 was released 20090410 +============================================================== + +* 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. + +============================================================== +Luatex beta-0.37.0 was released 20090331 +============================================================== + +* Luatex now implements shell_escape = 'p', a new feature + in web2c that intends to make \write18 more secure. As + a side-effect, if luatex is used for typesetting, it will + now also apply shell_escape = 'p' and shell_escape = 'f' + to the lua functions io.popen(), os.execute(), os.exec(), + and os.spawn(). + Nothing has changed for the case where luatex is used as + a script interpreter. + +* Attributes can now have negative values. The special value + for 'unset' is lowered to -0x7FFFFFFF (it used to be -1). + +* The lua 'kpse' library now has an object-oriented interface + as companion to the procedural interface. This is useful for + e.g. controlling the discovery of mplib files. + +* The new internal integer parameter \outputbox allows setting + of the output box number (default: 255, max: 65535) + +* The new primitives \Udelimiterunder and \Udelimiterover + complete the set of 'StretchStacks' for OpenType Math. + +* Fixed a bug in font string conversions on the Macintosh that + resulted in warnings about 'unaligned pointers being freed'. + +* Khaled Hosny spotted a bunch of manual errors. + +* There was bug in the width of math_accent objects when + there were super- or subscripts attached to the accentee. + +* In PDF mode, TRT \leaders were bugged. + +* The source tree now uses the new texlive build system that + Peter Breitenlohner created. + +* There is now a single build.sh instead of four separate + ones. It has a few options: + --make : only make, no make distclean; configure + --parallel : make -j 2 -l 3.0 + --nostrip : do not strip binary + --mingw : crosscompile for mingw32 from i386-linux + --ppc : crosscompile for ppc osx on intel osx + + Note: --parallel still sometimes causes crashes due to + timing errors, so use that option with care. + +* Many compiler warnings have been removed (but not all yet). + +============================================================== Luatex beta-0.36.0 was released 20090323 ============================================================== @@ -538,7 +698,7 @@ Other news: we probably introduced new problems as well). * Most (all?) files now have a corrected Copyright header, - and link in $Id$ and $URL$ into the object file. + and link in $Id$ and $URL: http://scm.foundry.supelec.fr/svn/luatex/trunk/source/texk/web2c/luatexdir/NEWS $ into the object file. * Some unnecessary files were removed from the distribution. |
