103 ** There is initial support for 30-bit integers in elisp (normally,
104 integers are only 28 bits wide on 32-bit machines.) Compile with
105 -DUSE_MINIMAL_TAGBITS to test. With this change, the maximum buffer
106 size on 32-bit machines is bumped from 128M to 512M.
107
108 ** The internal image code now uses the ImageMagick library as an
109 interface to various image-related functions. You still need the
110 other libraries to build the image support, though.

145 ** The line number tracking in modeline is now efficient, even for
146 very large buffers. This is achieved by caching the line numbers of
147 recent buffer positions, and reusing them. This cache is used only in
148 the buffers where `line-number-mode' is in effect.
