    [tmac]: Drop AT&T troff font aliases/remappings.
    
    Now that we have working diagnostics for font selection problems, users
    will be made aware of portability issues and can address them where they
    feel appropriate; in a document, in the "troffrc" file, or by modifying
    these files.

 Macro packages
 --------------
 
+o The device-specific macro files loaded by "troffrc" automatically on
+  startup, such as "ps.tmac" and "html.tmac", no longer perform font
+  translations for font names used by varieties of AT&T troff ('C',
+  'Hb', 'HX', and many others).  These names are not portable: in AT&T
+  troff, the font repertoire, like the special character repertoire, was
+  device-dependent.  Since groff 1.23.0, our diagnostic messages report
+  problems with attempts to use nonexistent font names.  We recommend
+  addressing such portability issues wherever suits you; in a document,
+  perhaps by using `ie` and `el` requests and the `.g` register to test
+  for groff extensions; in your "troffrc" file; or by modifying these
+  macro files.  Users of the "dvi" and "lbp" output devices should be
+  aware that these devices don't supply full families of monospaced
+  fonts (and never have).  See grodvi(1) and grolbp(1).

 o Hyperlink support is now enabled by default on non-HTML devices that
   support it (PDF and terminal devices) for an (man) documents.
