Be sure to read the README.txt and RELEASE-NOTES.txt that are supplied in the zipfile.

Upgrading users are advised to enable the "old baro calc" for backwards compatability.

Some of the ini changes will result in harmless warnings when loading MSQs from 1.4.x
Users upgrading from 1.2.x or earlier codes need to pay more attention.
TunerStudio 3.0.x or later is REQUIRED.

Go ahead and use the built-in firmware loader on the Tools menu of TunerStudio 3.0.x - you'll like it.

CAN EGO is an option for v1.5 a4, but is missing in a5. (just checked)

Feedback. Closed loop boost isn't working. Boost works in open loop, but not closed loop. Back ported to 1.5.4 and closed loop boost works again

I have logs and can post later is needed

Feedback. Closed loop boost isn't working.

Thanks for the tunes and logs. There was a one line typo to blame. Looks back to normal on the bench.

The fix will be out soon.

Closed loop target boost table blending by flex% still isn't working.
Flex% is reading 80%, but it's using the unleaded target table.

[edit]
Oh, I should have read the above first
James, if you have a quick build you want tested, ill give it a go.

I wasn't aware of a reported issue, but I just tested what I believe to be the scenario on the bench and it seems to be working now.
