[tex-k] [WEB] Outdated 'webmac.tex' in TeX Live 2021!

[Andreas Scherer]

> As far as I can tell TL is current.
Weird, 'tlmgr info knuth-lib' reports

package:     knuth-lib
category:    Package
shortdesc:   Core TeX and Metafont sources from Knuth
longdesc:    A collection of core TeX and Metafont macro files from DEK, 
apart from the plain format and base. Includes the MF logo font(s), 
webmac.tex, etc.
installed:   Yes
revision:    58216

and 'kpsewhich webmac.tex' points to
/opt/texlive/2021/texmf-dist/tex/plain/knuth-lib/webmac.tex

which was last installed in March
-rw-r--r-- 1 andreas andreas 10084 Mär 10 09:52 .../webmac.tex

and yet it is outdated
$ grep WEBMAC `kpsewhich webmac.tex`
\xdef\fmtversion{\fmtversion+WEBMAC4.1} % identifies current set of macros

After 'tlmgr install --reinstall knuth-lib' I get an older SVN revision

package:     knuth-lib
category:    Package
shortdesc:   Core TeX and Metafont sources from Knuth
longdesc:    A collection of core TeX and Metafont macro files from DEK, 
apart from the plain format and base. Includes the MF logo font(s), 
webmac.tex, etc.
installed:   Yes
revision:    57963

with the current contents

$ grep WEBMAC `kpsewhich webmac.tex`
\xdef\fmtversion{\fmtversion+WEBMAC4.2} % identifies current set of macros

Case closed,
Andreas
