They have now. However 2.6 uses different package names, configuration file name, log file etc. It is generally mongod instead of the earlier mongodb (eg before it was /etc/mongodb.conf and is now /etc/mongod.conf). This means no automatic upgrades to 2.6, and sysadmin action to correct config file name etc.
