+New in 3.0.1:
+
+* Bug fix.
+
+New in 3.0:
+
+* Added option --output that allows to specify the output file name.
+* Some options have been renamed:
+ --hash-fn-name=NAME --> --hash-function-name=NAME
+ --lookup-fn-name=NAME --> --lookup-function-name=NAME
+ --compare-strlen --> --compare-lengths
+ --global --> --global-table
+ The older variants are still supported for backward compatibility.
+* The following options can now be specified inside the input file:
+ %delimiters=DELIMITER-LIST
+ %struct-type
+ %ignore-case
+ %language=LANGUAGE-NAME
+ %define slot-name NAME
+ %define initializer-suffix INITIALIZERS
+ %define hash-function-name NAME
+ %define lookup-function-name NAME
+ %define class-name NAME
+ %7bit
+ %compare-lengths
+ %compare-strncmp
+ %readonly-tables
+ %enum
+ %includes
+ %global-table
+ %pic
+ %define string-pool-name NAME
+ %null-strings
+ %define word-array-name NAME
+ %switch=COUNT
+ %omit-struct-type
+* When the option -k is not given, the default key positions are now
+ computed depending on the set of keywords.
+* If the input file is given by name, the output file will now contain
+ #line directives referring to the input file.
+* Some keyword sets containing permutations, like { "xy", "yx", "xz", "zx" }
+ or { "abc", "acb", "bca", "cab" }, are now handled by gperf without
+ requiring the option -D.
+* The generated table is usually much smaller than it was with earlier
+ versions of gperf.
+* Added option -m/--multiple-iterations that allows to further reduce the
+ size of the generated table.
+* When the search for a good hash function is not immediately successful,
+ the table's size will grow as needed. Earlier versions of gperf bailed
+ out with an "Internal error, duplicate hash code value".
+* The options -f/--fast and -o/--occurrence-sort have no effect any more.
+* Added options -P/--pic and --null-strings that optimize the generated code
+ for use in shared libraries. -P/--pic does a perfect optimization but may
+ require some small code changes (see the documentation for details), whereas
+ --null-strings does only a half-hearted optimization but works without
+ needing any change to surrounding code.
+* Added option --ignore-case that produces a case independent lookup function.
+* Bug fixes.
+
+New in 2.7.2:
+
+* Keywords may now be enclosed in double quotes; this permits the use of
+ '#', ',', space or NUL inside keywords.
+* Bug fixes.
+
+New in 2.7.1:
+
+* Added option "-F" for gcc.
+
+New in 2.7:
+
+* gperf is now a stand-alone package, untied from libg++.
+* Autoconfiguring.
+* Removed the "-a" and "-g" options, extended the "-L" option instead.
+* Removed the "-p" option, it is the default.
+* Added long options ("--help", "--version" etc.).
+* 8-bit cleanliness is now the default; use "-7" to get the old behaviour.
+* Compiles with any C++ compiler.
+* Numerous small improvements.
