* Licence changed from GNU Lesser GPL 2.1 to GNU Lesser GPL 3.0
Version 2.24
* Added a #date meta-macro allowing for formatting of dates and
times
Version 2.23
* Fixed a bug where #error and #warning directives were processed
in the false branch of a conditional
Version 2.22
* Added --include option which allows user to specify a file
to be processed before the regular input file
Version 2.21
* Added CPP-style #error and #warning meta-macros
Version 2.20
* GPP's arithmetic evaluation macro (#eval) now supports
file-globbing via =~ (POSIX only)
* there is now an #elif macro to simplify conditional branching
* fixed a bug where GPP would be off by one when reporting line
numbers in its error messages or with the #line meta-macro
Version 2.14
* fixed a crash bug
* added built-in macros `line' and 'file'
* GPP documentation is now under a free licence
Version 2.13
* fixed bug which caused GPP to crash when the same macro was
defined twice on the command line
* GPP should compile on more systems now; non-standard C functions
have been replaced with custom code
* INSTALL contains installation instructions for Windows, Unix,
and other systems.
* GPP now issues a warning on use of deprecated command-line
options
* GPP is now packaged in a manner similar to most GNU
programs, including a `configure' configuration/installation
script suitable for Unix-like systems
* credits moved from manual to AUTHORS and THANKS files
* CHANGELOG superseded by files ChangeLog (detailed, for
developers) and NEWS (brief, user-visible changes only)
* added list of bugs and wishes as BUGS and TODO
* minor changes (mostly typographical) to the manual
Version 2.12
* New command-line options:
- -X for XHTML mode
- --help displays command-line option summary
- --version displays version information
- "long options" -nostdinc, -nocurinc, etc. changed to --nostdinc,
--nocurinc, etc.
* fixed miscellaneous typographical, grammatical, and spelling
mistakes in documentation
* licence changed from GNU Library GPL 2 to GNU Lesser GPL 2.1
* distribution now includes copy of the licence
* new project maintainer: Tristan Miller
Version 2.1
* Bugfixes:
- bugfix in #defeval (can now be used to iteratively redefine a
macro in terms of its previous definition)
- bugfix in arithmetic evaluation (operator precedence between +
and -, and between * and / was wrong)
* Arithmetic evaluation:
- length(...) builtin in #eval
- all comparison operators revert to string comparison if
arithmetic evaluation fails in #eval
* Command-line options:
- +n does the opposite of -n (do not preserve linefeeds; place
*after* -C/-P)
- -O sends output to file and stdout simultaneously
- options to control directory search order for #include
- option to adjust warning level
- option to specify an include file marker to keep track of
#include directives and line numbers in output
* Misbehavior fixes:
- numbered argument sequences (#1...#9) are disabled outside of
definitions.
- if a construct terminated by a newline is nested in last
position within another construct, then the nested newline is
optional. Concretely, this means that " #define myeval #eval #1 "
is now valid.
- macros defined on the command line with -D... can take named
arguments. The syntax is: -Dmacro(arg1,...)=definition ; the
definition should conform to the rules of the mode specified on
the command-line, although the arguments are specified in
C-style syntax (but without spaces !)
- input line numbers are almost always preserved when
-includemarker is specified
* Miscellaneous:
- LaTeX version of the manual in addition to man and html formats.
