+ <p>As of OTP release 17, the OTP release number corresponds to
+ the major OTP version number. In the normal case, the OTP version
+ number will be constructed as
+ <c>&lt;Major&gt;.&lt;Minor&gt;.&lt;Patch&gt;</c>. However more
+ dot separated parts may exist. If all parts less significant than
+ <c>Minor</c> equals <c>0</c>, they are omitted when printing the
+ version. Release candidates have an <c>-rc&lt;N&gt;</c> suffix. The
+ OTP version as a concept was introduced in OTP 17.</p>
+ <p>OTP of a specific version is a set of applications of
+ specific versions. The application versions identified by
+ an OTP version corresponds to application versions that
+ have been tested together by the Erlang/OTP team at Ericsson AB.
+ An OTP system can however be put together with applications from
+ different OTP versions. Such a combination of application versions
+ has not been tested by the Erlang/OTP team. It is therefore
+ <em>always preferred to use OTP applications from one single OTP
+ version</em>.</p>
+ <p>In an OTP source code tree as well as in an installed OTP
+ development system, the OTP version can be read from the text
+ file <c>OTP_VERSION</c> in the OTP installation root directory
+ (<seealso marker="kernel:code#root_dir/0"><c>code:root_dir()</c></seealso>).</p>
+ <p>If the version read from the <c>OTP_VERSION</c> file in a
+ development system has a <c>**</c> suffix, the system has been
+ patched using the <c>$ERL_TOP/otp_build patch_app</c> tool. In
+ this case, the system consists of application versions from
+ multiple OTP versions. The version preceding the <c>**</c>
+ suffix corresponds to the OTP version of the base system that
+ has been patched.</p>
+ <p>On a target system (see the
+ <seealso marker="doc/system_principles:create_target">system principles</seealso>
+ documentation) no <c>OTP_VERSION</c> file will exist. This since
+ one easily can create a target system where it is hard to even
+ determine the base OTP version.</p>
+ <p>Note that if a development system is updated by other means
+ than <c>$ERL_TOP/otp_build patch_app</c>, the <c>OTP_VERSION</c>
+ file may identify wrong OTP version.</p>
