HISTORY

@ -1947,3 +1947,9 @@ Video Disk Recorder Revision History
- Fixed a new/delete malloc/free mismatch in ringbuffer.c (thanks to Stefan
Huelswitt for reporting this one).
- Improved CAM handling.
2003-02-09: Version 1.1.24
- Improved CAM handling (thanks to Reinhard Walter Buchner for a great deal of help
in debugging this). It is now possible to insert the CAM in any of the two slots,
to insert and remove it while VDR is running and even to have two CAMs inserted.
