+2006-03-27  Mark Lindner  <markl@neuromancer>
+
+	* libconfigcpp.c++ - added missing break statements in switch (from
+	  Lukas Zweifel)
+	* libconfig.c - don't strdup() a NULL string (from Lukas Zweifel)

+
+2006-03-20  Mark Lindner  <markl@neuromancer>
+
+	* scanner.l - added '%option nounistd' and regenerated with newest

+
+2006-03-17  Mark Lindner  <markl@neuromancer>
+
+	* grammar.y - bugfix; error & abort parsing if duplicate setting name
+	  encountered (previously caused a crash ... reported by Tobias Witek)
+	* scanner.l - bugfix; multi-line C-style comments were causing line
+	  number counting to be thrown off, because the newlines were being
+	  "eaten"
+	* <multiple> - various fixes to support building of DLLs on Windows.
+
+2005-11-26  Mark Lindner  <markl@neuromancer>
+
+	* grammar.y, scanner.l - always strdup() yytext, and free the memory
+	  in the grammar rules.
+
+2005-11-22  Mark Lindner  <markl@neuromancer>
+
+	* libconfigcpp.c++, libconfig.h++, libconfig.c, libconfig.h -
+	  Added Daniel's enhancements: methods & functions for reading/writing
+	  files, fixes for various memory leaks, etc.
+	* samples/* - Added Daniel's example code.
+	* docs/libconfig.texi - Updated documentation
+
+2005-09-28  Mark Lindner  <markl@neuromancer>
+
+	* libconfigcpp.c++, libconfig.h++, libconfig.c, libconfig.h
+	  Enhanced API to support modification of a configuration.
+	* libconfig.texi - updated manual
+
+2005-06-02  Mark Lindner  <markl@neuromancer>
+
+	* libconfigcpp.c++, libconfig.h++ - Added getName() method;
+	  fixed operator[](int) to work with groups; this allows iteration over
+	  a group's child settings. Added a missing break statement (bugfix
+	  submitted by Pablo Barrera Gonzalez). Added operator int() and
+	  operator float() to Setting; note that these may cause loss of
+	  precision since the actual values are stored internally as long
+	  and double, respectively.
+
+	* libconfig.h - added config_setting_name() macro
+
+	* libconfig.c - maintain two lists of children at each node; a sorted
+	  list and an unsorted list (to preserve the order of the settings as
+	  they appear in the file).
+	
+	* scanner.l - fixed scanner rule for comments. '#' no longer has to
+	  be in column 0 to be recognized as a comment. Added support for C
+	  and C++ style comments.
