There is a lot of links in many places that point to the documentation, even inside some messages in mongod. Those links do not include the version, and is causing problems to users and customer, because is not easy to realize that you are reading an article for a different version that the version you have installed.

Ideally, is a good practice to use the software version on the link even for the current in any kind of articles and messages. Currently is impossible to specify the version for the current stable.

2.4
http://docs.mongodb.org/v2.4/tutorial/install-mongodb-on-debian/

2.6
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/

The problem in 2.6 link is the fact that the current stable will change in the future, and there will be a lot of links for 2.6 that point to an incorrect documentation.
