This says that 5.x will change the database and that 4.23 will be able to read it. It does not say that 4.23 changes the database.

There are a few minor backwards incompatibilities to be aware of in calibre 5
  • Because calibre has now moved to Python 3, some third party plugins will no longer work, until they are also ported to Python 3. For status on the plugin porting effort, see here.
  • Because of the support for library wide annotations, the database format was slightly changed. While calibre 4.23 is able to open and operate with calibre 5 databases, older versions of calibre may have trouble.
