The ARMv37 architecture, also known as ARM7 or armhfp, is slated for implementation in Fedora Linux 32. All development efforts for ARM systems are planned to be focused on the ARM64 (Aarch64) architecture. The change has not yet been reviewed by the FESCo (Fedora Engineering Steering Committee), which is responsible for the technical part of the development of the Fedora distribution. If the change is approved, the last release to support 32-bit ARM systems will be Fedora 36, which will receive updates until June 2023.
The reasons for ending support for ARMv7 are cited as a general distancing of development for 32-bit systems, as some of Fedora's new security and performance enhancements are only available for 64-bit architectures. Until now, ARMv7 has been the last fully supported 32-bit architecture in Fedora (repositories for the i686 architecture were discontinued in 2019, leaving only multi-lib repositories for x86_64 environments).
