Fedora 43 Cleared To Ship With Zstd Initrd, Updated Compiler Toolchains & More

Written by Michael Larabel in Fedora on 22 July 2025 at 08:47 AM EDT. 3 Comments
The Fedora Engineering and Steering Committee (FESCo) this week voted to approve a number of new features/changes for the upcoming Fedora 43 release.

Among the newly-approved Fedora 43 changes that have been signed off by FESCo include:

- Golang 1.25 for providing the latest Go programming language support.

- Fedora's Anaconda installer is cleared to drop support for UEFI on MBR partitioned disks -- leaving only UEFI on GPT partitions support.

- Cross-compilation support for the Free Pascal Compiler shipped by Fedora Linux.

- LLVM 21 is cleared to ship in Fedora 43 for providing the latest LLVM 21, Clang 21, and other LLVM toolchain updates. LLVM 21 stable will be released in the next month or so.

- Fedora 43 will also ship an updated GNU compiler toolchain consisting of GCC 15.2, GNU Binutils 2.45, GNU C Library 2.42, and GNU Debugger 17.1.

- Zstd compression of the initrd by default for space savings and faster boot speeds.

- Preserving debug information within static libraries.

More details via this FESCo thread for the items voted on within their tickets this week.

Fedora 43 is currently aiming for release on 11 November.
