The OTP version as a concept was - introduced in OTP 17. In the normal case, the OTP version will be - constructed as - <c><Major>.<Minor>.<Patch></c> where <c><Major></c> - is the most significant part. However, more dot separated parts than - this may exist. The dot separated parts consists of integers. If all - parts less significant than <c><Minor></c> equals <c>0</c>, they - are omitted. The three normal parts - <c><Major>.<Minor>.<Patch></c> will be changed as - follows:</p> - <taglist> - <tag><c><Major></c></tag><item>Increased when major changes, - including incompatibilities, have been made.</item> - <tag><c><Minor></c></tag><item>Increased when new functionality - has been added.</item> - <tag><c><Patch></c></tag><item>Increased when pure bug fixes - have been made.</item> - </taglist> - <p>When a part in the version number is increased, all less significant - parts are set to <c>0</c>. Release candidates have an <c>-rc<N></c> - suffix. The suffix <c>-rc0</c> will be used during development up to - the first release candidate.</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>Application versions will be managed the same way as the OTP version. - Application versions part of a release candidate will however not have an - <c>-rc<N></c> suffix as the OTP version. Also note that a major - increment in an application version does not necessarily imply a major - increment of the OTP version. This depends on whether the - major change in the application is considered as a major change for - OTP as a whole or not.</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>$ERL_TOP/otp_build patch_app</c> tool. In - this case, the system consists of application versions from - multiple OTP versions. The version preceding the <c>**</c> - suffix corresponds to the OTP version of the base system that - has been patched. Note that if a development system is updated by - other means than <c>$ERL_TOP/otp_build patch_app</c>, the - <c>OTP_VERSION</c> file may identify wrong OTP version.</p> - - <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> -</chapter> - |
