18870SrgrimesNew in 3.0.3:
250476Speter
38870Srgrimes* The generated C code is compatible with gcc-4.3.x in c99 or gnu99 mode.
42116Sjkh
52116SjkhNew in 3.0.2:
68870Srgrimes
72116Sjkh* Compiles with g++-4.0.x.
82116Sjkh* Added option --length-table-name.
98870Srgrimes* Added declaration %define length-table-name.

112116Sjkh
128870SrgrimesNew in 3.0.1:
138870Srgrimes
142116Sjkh* Bug fix.
152116Sjkh
162116SjkhNew in 3.0:
172116Sjkh
188870Srgrimes* Added option --output that allows to specify the output file name.
198870Srgrimes* Some options have been renamed:
2087804Sphantom    --hash-fn-name=NAME     -->   --hash-function-name=NAME
212116Sjkh    --lookup-fn-name=NAME   -->   --lookup-function-name=NAME
222116Sjkh    --compare-strlen        -->   --compare-lengths
232116Sjkh    --global                -->   --global-table
242116Sjkh  The older variants are still supported for backward compatibility.
252116Sjkh* The following options can now be specified inside the input file:
268870Srgrimes    %delimiters=DELIMITER-LIST
272116Sjkh    %struct-type
282116Sjkh    %ignore-case
292116Sjkh    %language=LANGUAGE-NAME
302116Sjkh    %define slot-name NAME
318870Srgrimes    %define initializer-suffix INITIALIZERS
322116Sjkh    %define hash-function-name NAME
332116Sjkh    %define lookup-function-name NAME
348870Srgrimes    %define class-name NAME
352116Sjkh    %7bit
362116Sjkh    %compare-lengths
378870Srgrimes    %compare-strncmp
382116Sjkh    %readonly-tables
392116Sjkh    %enum
408870Srgrimes    %includes
412116Sjkh    %global-table
428870Srgrimes    %pic
432116Sjkh    %define string-pool-name NAME
4433662Sjb    %null-strings
4533662Sjb    %define word-array-name NAME
4633662Sjb    %switch=COUNT
4733662Sjb    %omit-struct-type
4833662Sjb* When the option -k is not given, the default key positions are now
4933662Sjb  computed depending on the set of keywords.
5042044Sdfr* If the input file is given by name, the output file will now contain
5142044Sdfr  #line directives referring to the input file.
5233662Sjb* Some keyword sets containing permutations, like { "xy", "yx", "xz", "zx" }
5322808Sbde  or { "abc", "acb", "bca", "cab" }, are now handled by gperf without
542116Sjkh  requiring the option -D.
552116Sjkh* The generated table is usually much smaller than it was with earlier
5622731Sbde  versions of gperf.
572116Sjkh* Added option -m/--multiple-iterations that allows to further reduce the
58117917Sbde  size of the generated table.
59117917Sbde* When the search for a good hash function is not immediately successful,
6033662Sjb  the table's size will grow as needed. Earlier versions of gperf bailed
612116Sjkh  out with an "Internal error, duplicate hash code value".
6293211Sbde* The options -f/--fast and -o/--occurrence-sort have no effect any more.
632116Sjkh* Added options -P/--pic and --null-strings that optimize the generated code
642116Sjkh  for use in shared libraries. -P/--pic does a perfect optimization but may
652116Sjkh  require some small code changes (see the documentation for details), whereas
66117909Speter  --null-strings does only a half-hearted optimization but works without
672116Sjkh  needing any change to surrounding code.
682116Sjkh* Added option --ignore-case that produces a case independent lookup function.
6993211Sbde* Bug fixes.
7093211Sbde
712116SjkhNew in 2.7.2:
722116Sjkh
732116Sjkh* Keywords may now be enclosed in double quotes; this permits the use of
742116Sjkh  '#', ',', space or NUL inside keywords.
752116Sjkh* Bug fixes.
762116Sjkh
772116SjkhNew in 2.7.1:
782116Sjkh
792116Sjkh* Added option "-F" for gcc.
802116Sjkh
812116SjkhNew in 2.7:
822116Sjkh
8391514Sobrien* gperf is now a stand-alone package, untied from libg++.
842116Sjkh* Autoconfiguring.
852116Sjkh* Removed the "-a" and "-g" options, extended the "-L" option instead.
862116Sjkh* Removed the "-p" option, it is the default.
872116Sjkh* Added long options ("--help", "--version" etc.).
882116Sjkh* 8-bit cleanliness is now the default; use "-7" to get the old behaviour.
892116Sjkh* Compiles with any C++ compiler.
902116Sjkh* Numerous small improvements.
