Package aliascnt Warning: The package is obsolete

[paolieri]

I get this warning on Overleaf:

This is pdfTeX, Version 3.141592653-2.6-1.40.29 (TeX Live 2026) (preloaded format=pdflatex 2026.6.26)  12 SEP 2026 08:34

Package: aliascnt 2026-03-08 v1.7 Alias counters (HO)

Package aliascnt Warning: The package is obsolete. Check the documentation. on input line 62.

)

The reason is that aliascnt is now obsolete and \newcounteralias was added to the kernel.

I could patch pseudo.sty as follows:

1. Replaced \RequirePackage{aliascnt} with:

\cs_if_exist:NF \newcounteralias { \RequirePackage{aliascnt} }

2. Replaced \newaliascnt { #1 } { #2 } with:

 \cs_if_exist:NTF \newcounteralias
     { \newcounteralias { #1 } { #2 } }
     { \newaliascnt     { #1 } { #2 } }

This should work with old and new Latex installations.
