+ <p>
+ When a new OTP release is released it will have an OTP
+ version on the form <c>&lt;Major&gt;.0</c> where the
+ major OTP version number equals the release number.
+ The major version number is increased one step since the
+ last major version. All other OTP versions with the same
+ major OTP version number are patches on that OTP release.
+ </p>
+ <p>
+ Patches are either released as maintenance patch packages
+ or emergency patch packages. The only difference is that
+ maintenance patch packages are planned and usually contain
+ more changes than emergency patch packages. Emergency patch
+ packages are released to solve one or more specific issues
+ when such are discovered.
+ </p>
+ <p>
+ The release of a maintenance patch package usually imply
+ an increase of the OTP <c>&lt;Minor&gt;</c> version while
+ the release of an emergency patch package usually imply an
+ increase of the OTP <c>&lt;Patch&gt;</c> version. This is
+ however not necessarily always the case since changes of
+ OTP versions are based on the actual changes in the code
+ and not based on whether the patch was planned or not.
