The current default version of gcc in Ubuntu 20.04LTS is 9.3. Will this change over the lifetime of 20.04LTS?

I'm writing a book that looks at the assembly language generated for C and C++ code by gcc. It's an introductory book, so the code is very simple. I want to keep things simple for the reader. The simplest thing would be for the reader to install 20.04LTS and use the default compiler.

I've installed gcc 10.2. If 10.x will become the default for 20.04LTS over the next year or so, I would be inclined to use that for my examples in the book.

Again, this is an introductory book, so I want to keep things as simple as possible for the reader to do their programming.
