Pay attention to everything that does or may have impact on your Samba 
installation.

Most important are the major changes listed at the beginning of the RN. 
Additionally, it's important to know about new/removed/deprecated 
parameters, and if defaults have been changed.

Also the list of bugs that have been fixed may be interesting. Maybe you 
see that a problem is fixed that affected you. Additionally it's good to 
know what we fixed, in case you later have related problems. Maybe the 
fix introduced a regression. For example, the latest release fixes a 
regression, introduced by a fix in the previous version.

Everything in the RN is good to know. That's why we put it there. :-)

Read the x.y.0 RN from the major releases + the all for minor versions 
of the new branch.

For example, if you want to switch from 4.4.5 to 4.6.2, read the RN from:
- 4.5.0
- 4.6.0
- 4.6.1
- 4.6.2
to know what has been changed between your current and the version you 
want to install.
