It is possible to run applications with a MATLAB Runtime Update level that does not match the MATLAB Release used to compile the application?

A new update was recently released for MATLAB. The MATLAB Runtime available on the MathWorks website was updated accordingly to match the newest update release number:

However, the standalone application was compiled using an older update release number of MATLAB. Will applications compiled with an older update of MATLAB work with the newer update of MATLAB Runtime for the same release, and vice-versa?

The compiled applications are tied to the release and not to specific updates. For example, if you have compiled an application using MATLAB R2021b Update 3, the application will launch with any R2021b version (v9.11) of the MATLAB Runtime. However, whether it will work as expected is dependent on whether the application is dependent on a bug fix in that particular update.

You can ensure compatibility by creating an application installer using our MATLAB Compiler apps such as the Application Compiler or Library Compiler. Our application installers will ensure that the installed runtime is at an update level equal to or greater than the update level of the MATLAB that created it.
