Heads up!

With the transition to xml2rfc vocabulary version 3, xml2rfc has gained
the ability to generate PDF output when the necessary system libraries
are installed.  However, xml2rfc runs on Python 2.7, but the library
needed for PDF generation ended support for Python 2.7 about 10
releases ago.  This means that the need to end support for xml2rfc on
Python 2.7 is becoming urgent.  Another factor is that bugfix support
for Python 2.7.x itself officially stops on 1 January 2020, so we need
to transition away from Python 2.7 soon in any case.

The latest xml2rfc release is 2.32.0.  There will most likely be one or
two additional xml2rfc releases in the 2.x series, but after that, the
plan is to transition to a 3.x release series, with two major changes:

(1) xml2rfc will no longer run under Python 2.7; it will require
    Python 3.5 or higher.  If you cannot install and run Python 3 on
    your system, the web service at xml2rfc.ietf.org can be used.

(2) The default output formatters will change to v3.  The v2 formatters
    will still be available by using a --legacy switch.

Expect the first xml2rfc 3.x series release before the end of the month.
