Removal of Omega 1.15
Omega 1.15 is obsolete and has now been removed from the distribution.
Windows 8.3 file names
In the past, it was possible to specify Windows 8.3 file names (aka
short file names) when invoking a TeX engine. As of 2.9.7440, this is
not supported anymore.
Impact: The following use case is broken:
pdflatex abraka~1.tex
where abraka~1.tex is the 8.3 variant of the long file name abrakadabra.tex.
Package database signing
In the past, package database signing was optional. As of MiKTeX
2.9.7440, it is required that MiKTeX package database files are
provided with a valid signature.
Reason: In order to support custom remote package repositories (see
Allow local http
mirrors), it must be
ensured that the conntents of the custom package repository is
unmodified.
Impact: Users will receive an error message if they visit an outdated
(no signature) or modified (tampered database) package repository.
Unrestricted shell escape commands and elevated privileges
As of MiKTeX 2.9.7440, it is possible to prevent the execution of
unrestricted shell escape commands when a program is running with
elevated privileges:
initexmf --verbose --set-config-value [Core]AllowUnrestrictedSuperUser=f
This prevents the following use case:
sudo pdflatex --shell-escape file.tex
where file.tex contains:
\documentclass{minimal}
\usepackage{shellesc}
\begin{document}
\ShellEscape{echo hello, world! > hello.txt}
\input{hello.txt}
\end{document}
