19   - GNU grep can now be built with autoconf 2.52.
21   - The new option --devices controls how grep handles device files. Its usage
28     grep -e '\(a\)\1' -e '\(b\)\1'
44     . The -q or --quiet or --silent option now causes grep to exit
62   - The new -P or --perl-regexp option tells grep to interpert the pattern as
65   - The new option --max-count=num makes grep stop reading a file after num
73   - Added more check in configure to default the grep-${version}/src/regex.c
78   - If the final byte of an input file is not a newline, grep now silently
81   - The new option --binary-files=TYPE makes grep assume that a binary input
92   - egrep is now equivalent to `grep -E' as required by POSIX,
94     `grep' is now more forgiving about stray `{'s, for backward
107   - New option --mmap.  By default, GNU grep now uses read instead of mmap.
110   - The new option -z or --null-data causes `grep' to treat a zero byte
114   - The new option -Z or --null causes `grep' to output a zero byte
122     e.g. GREP_OPTIONS='--directories=skip' reestablishes grep 2.1's
126     `grep -E -E' or `fgrep -F'.  It is still an error to specify
135     (This option was also in grep 2.3, but wasn't announced here.)
142   - When searching a binary file FOO, grep now just reports
148     The new -a or --text option causes `grep' to assume that all
152   - `grep' now searches directories just like ordinary files; it no longer
154     Unix text utilities (in particular, of traditional `grep').
155     Hence `grep PATTERN DIRECTORY' should report
156     `grep: DIRECTORY: Is a directory' on hosts where the operating system
158     `grep: DIRECTORY: Binary file matches' (or nothing) otherwise.
161     `-d skip' causes `grep' to silently skip directories, as in grep 2.1;
162     `-d read' (the default) causes `grep' to read directories if possible,
163     as in earlier versions of grep.
207 disappeared as separate programs into the single grep program mandated
209 selecting grep, egrep, and fgrep behavior respectively.  For
222 dependent, but (for example) grep 2.0 typically runs at least 30% faster
223 than grep 1.6 on a DECstation using the MIPS compiler.  Where possible,
224 grep now uses mmap() for file input; on a Sun 4 running SunOS 4.1 this
