  * This is a simple program to limit the cpu usage of a process
  * If you modify this code, send me a copy please
  *
- * Date:    29/8/2008
- * Version: 1.2 alpha
+ * Date:    30/8/2008
+ * Version: 1.2 beta
  * Get the latest version at: http://cpulimit.sourceforge.net
  *
- * Changelog:
- * - experimental support for daemonize
- * - control algorithm has been optimized
- * - no longer segmentation fault when some processes exit
- * - no longer memory corruption when some processes exit
- * - cpulimit exits if --lazy option is specified and the process terminates
- * - light and scalable algorithm for subprocesses detection and control
+ * Changelog from 1.1:
+ * - reorganization of the code, splitted in more source files
  * - cpu count detection, i.e. if you have 4 cpu, it is possible to limit up to 400%
- * - in order to avoid deadlock, cpulimit prevents to limit itself
+ * - in order to avoid deadlocks, cpulimit now prevents to limit itself
+ * - option --path eliminated, use --exe instead both for absolute path and file name
+ * - call setpriority() just once
+ * - no more segmentation fault when processes exit
+ * - no more memory corruption when processes exit
+ * - cpulimit exits if --lazy option is specified and the process terminates
+ * - target process can be created on-fly given command line
+ * - light and scalable algorithm for subprocesses detection and limitation
+ * - mac os support
  * - minor enhancements and bugfixes
  *
