Sorry PG, but this is still a sad excuse.
The support cut off ALL CONTACTS with the comment “It’s the 3rd party developers fault” - which wasn’t the first time btw (the same happened to me with my C7 reports, until I insisted on taking a closer look with the ASIO engine, and it was the first answer before my issue was even properly looked at with WL8!). And i know for a fact that Slate Digital/Eiosis (Fabrice Gabriel) contacted you on this issue. I also gave you very detailed bug reports, the “dev section” even asked further questions, asked to provide more data. Aside from two plugins from two different companies I forwarded you to, all plugins I mentioned were available to the public (mind you, not freeware!). Yet the support wrote me “according to our research, the plugins do not exist”.
Oh-kay!
Furthermore, people like U-HE stick to the VST3 specs like a fly to honey, yet the dev team still ran into issues with SATIN (but could thankfully fix it with a workaround). The “VST3 Audio Forward Bug”, as it’s infamously called among developers I beta test for, is existing since WL7 (!, so… almost 4 years now?!). Don’t tell me that high rollers like Nugen Audio did not code according to specs as well?
The VST3 SDK is an undocumented mess. That should be apparent by various angry comments through both the SDK ML and various web boards for VST Plugins. And Steinberg is the only host developer, where there need to be workarounds in 3rd party plugins. Totally understandable - especially if the VST3 plugins work in Cubase, but not in Wavelab.
But who am I to criticize? I’m just a mere paying user.
Then regarding the 8.0.4 update.
Thanks for the information. It was announced on KVR Audio, but was apparently not available to the public yet by Monday. The news post on Steinberg.net is also brand new (so to speak, 09th July - so that’s today)
I am also surprised to see a WL8.5 demo this time around - only with a 1 month and 3 days delay. That is a new one.
Though I do have a question on that behalf:
If I demo it, and then decide to update from my existing WL8.0 license, will the “demo” license be deleted from my USB key?
Now it’s down to testing again. But if you say that it’s for “internal plugins only”, then it’s once more moving the Old Maid over to the third party devs. Unless the issues have suddenly poof’d into thin air, then I consider this a silent confession that something was once again wrong on the host side of things.
Oh and greetings to the support!
A short and simple mail with “This will be addressed in the maintenance updates, due - please stay tuned” would have sufficed. Instead I got a “not our fault - furthermore I’m out of the office the next weeks, send in a new ticket if you have further questions”. 
And you wonder why the board is clogged with questions and disgruntled posts like these.
