{{{
* Noteworthy changes in release 4.6 (2018-12-19) [stable]
** Improvements
sed now prints a clear error message when r/R/w/W (and s///w) commands
are missing a filename. Previously, w/W commands would fail with
confusing
error message, while r/R would be a silent no-op.
sed now uses fully-buffered output (instead of line-buffered) when
writing to files. This should noticeably improve performance of "sed -i"
and other write commands.
Buffering can be disabled (as before) with "sed -u".
sed in non-cygwin windows environments (e.g. mingw) now properly handles
'\n' newlines in -b/--binary mode.
** Bug fixes
sed no longer accesses invalid memory (heap overflow) when given invalid
backreferences in 's' command [bug#32082, present at least since
sed-4.0.6].
sed no longer adds extraneous NUL when given s/$//n command.
[related to bug#32271, present since sed-4.0.7]
sed no longer accesses invalid memory (heap overflow) with s/$//n
regexes.
[bug#32271, present since sed-4.3].
** New Features
New option, --debug: print the input sed script in canonical form
and annotate program execution.
