As a result of practical issues on bug 7661 we were forced to remove the correct version and release numbers from the examples in the documentation. This is something we'd like to revert once we are able to.
The core issue was that we have separate builds for the client and server, but a common documentation. That means that the documentation generated as part of the server build will have incorrect release numbers.
To fix this we'd need to either:
a) Separate build numbers from release numbers (bug 7667)
b) Split the documentation in to client and server documentation (bug 6967)
Note that this can be a bit tricky after bug 4951 as reStructuredText doesn't allow much formatting nesting, so substitution markup won't work everywhere.
