Hi Akira, hi all, (please cc, not on the list)
(2) New primitives \pdfinfoomitdate and \pdftrailerid. If \pdfinfoomitdate=1, date is omitted. If \pdftrailerid{somestring}, somestring is used as the trailer. It can be \pdftrailerid{}.
I am playing with this and found that it doesn't work without problems in ini files: $ pdftex -ini ***\relax entering extended mode *\input pdftexconfig.tex (/home/norbert/tl/2016/texmf-dist/tex/generic/tex-ini-files/pdftexconfig.tex) *\pdfinfoomitdate = 1 *\pdfsuppressptexinfo = 1 *\pdftrailerid{} ! Missing { inserted. <to be read again> { <*> \pdftrailerid{ } ? *\pdftrailerid{} * So the *first* call to \pdftrailerid (and \pdfinfo the same!) fails but the second call works out. It seems that there is a problem withthe caatcode of the { which only gets set after the error handler is entered. That is current TeX Live source (svn) build.
