I need to upgrade Symfony minor version from 4.2 to 4.3.
I check the official document and find there is only 4.0 to 4.1 and there is no description for which files should be edited manually. I follow the document and find that is not clear enough to do it.
I read the document on Stackoverflow before and upgraded it for 4.1 to 4.2 successfully and I want something like this.
