Fixes nothing I care about, none of the outstanding (and in my opinion serious) bugs have been addressed.
 
Don't turn on the Disable Reverb Multithreading option.  It's only changeable in the VST and when I turned it on, I couldn't load the HS Strings 1st Violin without it crashing both inside Cubase and stand-alone.  Changing the option back fixed that.
 
What's fixed and added in PLAY Software Update 6.0.5?

Add scroll bar to Voices of the Empire articulation list

Fix an issue with volume of repeated vowels in Wordbuilder

Remove blinking cursor from info panel in Libraries browser

Thanks Matt.
