Nice to hear that pdftex

is not frozen totally. Could you
      please implement 

      \localleftbox

and

\localrightbox macros from luatex
      (or Omega) to pdftex?

These are very useful macros for example I use it for links break in DVI mode. Where I close the
active link on the line break and reopen it on the next line. And this perfectly works in page breaks, footnotes, floats

Thanks, Linas

pdftex will in texlive 2021 change  in two places

1. links where \pdfstartlink is in a different boxing level as
\pdfendlink are no longer a fatal error but gives only a warning:

x\hbox{\pdfstartlink
    attr {/Border[0 0 1]}
    user{
        /Subtype/Link%
        /A<<%
         /Type/Action%
         /S/URI%
         /URI(blkub)%
         >>%
        } Linktext}
\pdfendlink

\bye

pdfTeX warning: \pdfendlink ended up in different nesting level than
\pdfstartl
ink


2. There are two new primitives \pdfrunninglinkoff &
\pdfrunninglinkon which allow to interrupt a running link for
example in the header or footer. 

Would it be possible to get this changes into luatex too?
