		 mod_cband - A per-user, per-virtualhost and per-destination bandwidth
			    limiter for the Apache HTTP Server Version 2


Changelog
=========

Version 0.9.7.5 (STABLE)
------------------------
13-11-2006 Lukasz Dembinski <dembol@cband.linux.pl>
* FIXED BUG: "CBand leaks memory in scoreboard read/write. The apr_file_open() function used in the functions
  that read and write the scoreboard files cause a memory leak since the file descriptors get allocated
  in the config memory pool, which isn't freed until Apache shuts down or restarts"
* FIXED BUG: "Swapped arguments in shmctl functions"
* Added truncf workaround for Solaris
* fixed HTML 4.0 Strict warnings

Version 0.9.7.4 (STABLE)
------------------------

28-05-2006 Lukasz Dembinski <dembol@cband.linux.pl>
* FIXED BUG: the module doesn't set normal speed after refresh period. The speed is still the same 
  as it was set by CBandExceededSpeed and isn't set to the normal speed after refresh period
  (thanks to Pawe³ Kustroñ <pawel.kustron@goin.pl>)
* Fixed small bugs in documentation
