Advisory:
=========

1. From ACP version : 2.45.0.27 and above, KSL dependency has been removed. 
   Please contact third party codec driver vendor for latest driver without KSL driver. 
   However, this ACP driver can work even with older third party drivers,but 
   it is recommended to update to the latest driver.
   
2. From ACP version : 2.89.0.58 + Realtek driver version 8964 and above, packet based mechanism 
   has been enabled to pass the HLK test items on 20H1 OS and above.
   All the compatibilities( update and backward compatibility scenarios )
   have been taken care of and all the OEMs are suggested to 
   adopt this new mechanism by contacting the third party codec vendor for updated driver.
   
3. ACP Version was modified to 6.0.0.0 due to new SOC related software changes(Rembrandt).
