Supported platforms
-------------------
-* OS X 10.6.x / Snow Leopard. It should also work for 10.7 / Lion,
- but I haven't personally tested it.
+* OS X 10.6.x / Snow Leopard, OS X 10.7.x / Lion and probably newer versions.
* Solaris 10. I have done limited testing on Solaris 11 and
OpenIndiana release 151a, and both appear to work.
-* FreeBSD 9.0, though please see the "FreeBSD 9.0 Release Notes"
- section below!
+* FreeBSD 9.0 and 10.0.
* Linux via SystemTap compatibility. Please see
[$ERL_TOP/HOWTO/SYSTEMTAP.md][] for more details.
