No big changes, but a sufficiently significant change in the functionality to require a new minor version, rather than just a new release number.
-Q options (see item `-Q...') now write
their output lines (to stdout)
prefixed by the option letters, so that the output of -Qf now
consists of lines starting `Qf '. This makes it easier to
disentangle the output if several of these options are present - it
was added when option -Qb was added - but means that any
scripts parsing the previous version's output would break.-Rf and -Rb added (see item `-R[fb] int,int,int'), to set the foreground and
background colours on the command line, rather than just using the
foreground special. This is still a
bit rudimentary, as it can be done only once, for the whole document.
