+years which are not related specifically to \PDF\ output, generally new

+across all engines (not necessarily by the same name), and some are or

+As of \TEXLIVE\ 2020, the \type{\input} primitive in all \TEX\ engines,
+including \PDFTEX, now also accepts a group-delimited filename argument,
+as a system-dependent extension, as in \type{\input\Lbrace
+foo.tex\Rbrace}. The usage with a standard space/token-delimited
+filename is completely unchanged.
+This group-delimited argument was previously implemented in Lua\TEX; now
+it is available in all engines. \ASCII\ double quote characters
+(\type{"}) are removed from the filename, but it is otherwise left
+unchanged after tokenization.
+This extension is unlike most others in that it affects a primitive in
+standard \TEX\ (\type{\input}), rather than being related to a new
+primitive, command line option, etc. This is allowed because additional
+methods of recognizing filenames are explicitly mentioned in
+\type{tex.web} as acceptable system-dependent extensions.
+Incidentally, this does not currently
