48 \section{New math font encodings}
50 A joint working group of the \TeX{} Users Group and the \LaTeX3
51 Project is developing a new 8-bit math font encoding for \TeX{}.
52 It is designed to overcome several limitations and implementation
53 problems of the old math font encodings and to simplify switching
54 between different sets of math fonts, much as the \LaTeX{} font
55 selection interface has simplified switching between text fonts.
57 Since the work on this project relies entirely on volunteer work, we
58 cannot give a specific release date yet. However, a prototype
59 implementation already exists. This contains several sets of virtual
60 fonts, some \LaTeX{} packages and a kernel module; we hope to
61 integrate it into the main \LaTeX{} distribution for the next
62 release.
64 Documents using only standard \LaTeX{} commands for math symbols
65 should not be affected by switching to the new math font encodings
66 However, documents, classes or packages making specific assumptions
67 about the encoding of math symbol fonts are likely to break.
69 Further information about the Math Font Group may be found on
70 the World Wide Web at \texttt{http://www.tug.org/twg/mfg/}.
73 \section{A new math accent}
75 A new math accent, \verb|\mathring|, has been added. This is a math mode
76 version of the ring accent (\r{}) which is available in text
77 mode with the command \verb|\r|.
79 \section{Extended \cs{DeclareMathDelimiter}}
81 The command \verb|\DeclareMathDelimiter| has been extended.
82 Normally this command takes six arguments. Previously, when being used
83 to declare a character (such as \texttt{[}) as a delimiter, a variant
84 form was used with only five arguments. The argument specifying the
85 default `math class' was omitted. Now the full six-argument form may be
86 used in this case. The extra information is used to implicitly declare
87 the character via \verb|\DeclareMathSymbol| for use when the symbol is
88 not used with \verb|\left| or \verb|\right|.
90 The old five-argument form is detected and will work as before.

94 \section{Tools distribution}
96 The \texttt{multicol} package now supports the production of multiple
97 columns without balancing the last page. To get this effect use the
98 \texttt{multicols*} environment.
100 The \texttt{layout} package was partly recoded by Hideo Umeki to
101 display page layout effects in a better way.
103 As suggested by Donald Arseneau, the \texttt{calc} package was extended
104 to support the new commands \verb|\widthof{<text>}|,
105 \verb|\heightof{<text>}|, and \verb|\depthof{<text>}| within a
106 \texttt{calc}-expression. At the same time we modified a few kernel
107 commands so that \texttt{calc}-expressions can now be used in various
108 useful places such as the dimension arguments to the \texttt{tabular}
109 environment and the \verb|\rule| command. For many other standard
110 \LaTeX{} commands this was already possible.
113 \section{Support for Cyrillic encodings}
115 We are very pleased that, after a lengthy period of development, a set
116 of fonts, encodings and support files for using \LaTeX\ with Cyrillic
117 characters will soon be available.
119 Test versions of the `LH' fonts for these Cyrillic encodings, based on
120 the Computer Modern design, are available from CTAN archives in the
121 directory \texttt{fonts/cyrillic/lh-test}. The \LaTeX\ support files
122 (by Werner Lemberg and Vladimir Volovich) are also available from CTAN
123 archives in\\
124 \texttt{macros/latex/contrib/supported/t2}
127 \section{Default docstrip header}
129 Many \LaTeX\ users now distribute packages in documented source form
130 using the \textsf{docstrip} system. Docstrip allows a header to be
131 placed on generated package files, suitable for giving copyright
132 information, or distribution conditions.
134 We have changed the default version of this header so that it allows
135 stripped files to be distributed in ready-to-run installations such as
136 the \TeX{}Live CD\@. If you use the default header for distributing
137 your files you should check that the new copyright text is acceptable
138 to you. The file \texttt{docstrip.dtx} explains how to produce your own
139 header if you wish to do so.
