It has been a long time since its release Linux Mint 20. Eventually the distribution development team published instructions for the update. The remarkable thing is that this time you can only upgrade the Mint 19,3 64-bit.
The users running the 32-bit distribution are not so lucky.
The reason for this change is obvious, since Linux Mint 20 is based on Ubuntu 20.04 LTS, both operating systems are only available in 64-bit versions. Linux Mint 19.3 is the latest version to support the 32-bit architecture and will be available until April 2023.
