It has never happened before. If it works for you in 7.0 it will continue to do so at least as good in 7.2. But there is a tiny possibility, with esoteric hardware, that a bug that was not fatal in a previous version becomes fatal in the new one. This is very rare but if you are very concerned you can check this by downloading a live cd (e.g. ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-i386/7.2/7.2-RELEASE-i386-livefs.iso), booting it and testing a little.
