TeX/texk/web2c/News:
| 7.5.1 (17 February 2003)
| * New upstream sources from Knuth.
 
TeX/texk/web2c/ChangeLog:
| 2003-02-16  Olaf Weber  <olaf@infovore.xs4all.nl>
|         * tex.web: TeX 3.141592 from Knuth: fixed \xleaders, glueset,
|         weird alignments.
| 
|         * tex.ch: Update banner for TeX 3.141592.

The changes are already done. And it would be difficult to distinguish
between 3.14159 and 3.141592 at macro level. I would not want to read
the .log file for the version number in the banner.
