you can easily upgrade but you cannot easily downgrade.
therefore, if no strong reason to start out with the latest, it is probably safest and most flexible to start with the older version and then you can upgrade later if you needed specific features.
of course, using version control, you can relatively easily upgrade to newer version and check if the project works by making a build and testing. If you did that to ensure no hidden issues then you could safely move to new version without worries.
