 ## Current development status
 
-The application is currently in Alpha status. But I have now implemented the majority of the functionality I planned for the first release, so we are close to a first beta release.
+The application is currently in Beta status. I have now implemented all of the functionality I planned for the first release, it just wants testing.
 
 Missing functionality:
 - Not many errors are reported to the user.

 - Configure the PCM3060 filters.
 - Reports device information to the user (version numbers etc..)
 - Validates the firmware version is supported.
+- Completely custom Infinite Impulse Response (IIR) filters
 
 Known issues:
 - There is a burst of audio noise when when writing a config to flash, this seems to be due to the time it takes to write to flash. I turn the DAC off then back on to mask it, the slight pop sounds much better.
