When I try to download MCR 2022b, it appears the Update is 5
However the latest Update for MATLAB R2022b itself is Update 4.
What is the change of MCR Update 5 ? How can I be sure the deployed app will work identical to the test of the non-deployed code performed on Update 4 ?

You can force MATLAB to update to Update 5 if you run the update_installer.exe found in C:\Program Files\MATLAB\R2022b\bin\win64.
However, there don't seem to be any release notes for Update 5 yet, so I don't think we can be sure of anything yet. I wouldn't update anything to Update 5 if you depend on MATLAB/MCR for work.
EDIT: The release notes are now available from the link above.

@Bruno Luong why do you need the MCR? Just to distribute to your end users? I have the development environment with the compiler and if I compile my code into a standalone program I don't need the MCR to run it. It runs on my computer without it because I guess it finds whatever it needs in the development (main) folder. However if I deploy my executable to end users, they will have to somehow get the MCR (either I give it to them or they download it themselves).
  1. Are you compiling and distributing standalone programs?
  2. Do you install the MCR on your own development computer?

  1. Yes
  2. Not necessary but some time I do for testing
MCR is needed for anyone who run the the compiled application without MATLAB.
To reduce the risk I need to test/validate the app the same version of MCR and the MATLAB where test are performed.
TMW needs to understand this is important and stop messing around with update version.

I just tried to update on my personal, non-work computer. The bell icon in the upper left said something like "Update 5 is ready". So I clicked on it and it went though the install procedure but the window said "Updating to update 3" or something like that. And when it was all finished, it was update 3 that had been installed. I have no idea why.

Sure thing.
I haven’t heard of the bell notification installing a different update than what it displays. My guess is it had to do with the weirdness going on with Update 4. I think you’re right about it being a moot point, though.

I just successfully updated to Update 5 using the approach described in this Comment. When I launched MATLAB afterward, it noted that Update 5 had been installed. (That was in spite of something crashing my desktop mid-download. I just re-sttarted the download and everything worked.)
