Thanks for the replies
At the moment there are 2 Altium users here, I should have mentioned we're not using 365. I updated a couple of times in the past months and have am missing SVN update, my colleague stayed on an old release and still has it. I'm running Altium on both an office desktop and my laptop, both up to date (24.9.1), both now missing SVN update, so it's definitely one of their updates, I'll re-install on the laptop later.
I took a look at GIT, I see on my desktop there's a GIT repo (365), oddly though under Data Management "Create New" and "Connect To" only have a SVN option. We design for numerous customers each with their own SVN repo to avoid data cross contamination so ease of use is important, I'd rather not switch until there's a good level of support / integration and it's mature. When I get a free morning / afternoon I'll look some more.
