Updated IVA manual

[silvertail]

Just did a quick check and noticed that the IVA manual was updated on 3rd October.

It's available here:

I've had a scan through the changes and didn't find anything that would affect my build. FWIW, there's some changes to safety glass marking (but not to windscreens specifically) and new bits on electronic immobilisers and hybrids (!)
