Can someone confirm please.

The picture here clearly shows pin 1 as the top left pin of the JTag port:
EXTERNAL LINK 
But the PCB mask has pin 1 marked as the bottom left of the 10 pins.

Before I guess and destroy my board, could someone tell me which is correct please? Thanks.

Looked up the pin out and worked it out. It seems the image on the wiki is wrong and the pcb screen is correct. Which is actually reassuring!

Hi Martin - are you flashing a new core to your V4SA?  If so could you let me know how you get on? I'll have to wait for them to be released as exe files.

On Slack / IRC but they are heavy beta.

There will be .exe once its publicly ready, and in public download.

Yes, it was suggested that I should update to the one on slack.

It went well enough and was easy to do - but then I have done FPGA coding before so i already know the process. I can't say that I noticed any difference in my V4SA though. But without a changelog I wouldn't know if anything was likely to change.
