Noel Borthwick [Cakewalk]
2018.04.01 release notes are updated in the main forum post now. Scroll to the bottom of the message to read them.
This is the official release and fully tested so no longer early access status.

I must be very thick today, but I cannot find the release notes with that link.

Page 14 of that thread?  I must be looking in the wrong place Noel.

Found it here:

Correction - the latest release notes can be found towards the end of this post:

[Edit: tenfoot beat me to it!]

Existing SPLAT users, don't forget when you upgrade Assistant 3.0.8 you now have an option to Install Add On's.
 
I missed that option and it downloaded everything and it installed the Studio Instrument Suite without asking.
Then when I found this option I just upgraded the Theme Editor separately.
All working  100%

Manual is now available but only an online version the Option is gone from Preferences for offline viewing.

- I was then asked if I wanted to install Studio Instruments and clicked 'no'.
- I opened CbB and all seems well, including the Powr dithering options reappearing (thanks guys!)
- But: the Assistant is still saying 'a new version is available'.

 
I had a similar experience with the Studio Instruments.  Since it said something like the install would not be complete if I cancelled, I reluctantly allowed it to install Studio Instruments even though I already had it installed long ago.  I was wondering why that seemed to be forced.  Anyway, it did complete the install and I haven't seen any difference with the newly installed SI.
 
One other minor problem - Win10 Programs and Features shows 2 lines for Bandlab - one for version 3.0.6 and 3.0.8.  I thought it should have replaced the 3.0.6 line.  So I deleted the 3.0.6 version using Programs and Features and then both versions were deleted.  So then I re-downloaded BA, installed it, and I still have the 2 lines and can't seem to get rid of the 3.0.6 line.

YES- A progress bar would be very very nice!! 
The assistant update gives you zero feedback and I had to close and try again after 20 minutes of nothing happening. 
Second try worked right away and took 2 minutes. PITArse. 
Then I had to sign in AGAIN.. 3rd time. 
Then I click update for Cakewalk and once again,, is it doing anything?? OK a faded "downloading" is winking on and off for those with good eyesight. But one may ask...what is it downloading?? After 10 minutes it showed a green "Update" again?? I was busy typing this and when I looked again-- it's say's downloading again? what? Now I'm probably re downloading something I don't want.  Oh well I can afford the bandwidth right now, but there was a day when I had to be careful about my bandwidth usage. 
 
It's not a big deal but I can't think of any other software installers that are this candid about what is going on. 
 
Overall I'm in a good mood as this is excellent stuff and looking forward to an improved version. Bug fixes--bring em on,,, forget the fancy features, lets' get rid of every single bug first,, right on...Good job Noel, Ben and team. 

Great job Meng + Noel + Team -- great to see such a good start! Keep it up!

I take ownership for the thickness - I originally posted the wrong link :-P
I was outdoors and couldn't edit from my phone afterwards so thanks to Ben for fixing it.
