Microsoft on Monday released Azure Linux 3.0.20251206 as the newest monthly update to its in-house Linux distribution used within the Azure cloud and elsewhere at the Windows company.
Azure Linux 3.0.20251206 adds the DM-CACHE module to its kernel for allowing better performance out of block devices, enables additional kernel build options like SCHED_core, and continues expanding its AArch64 support with enabling more packages like Kata Containers there.
This December update to Azure Linux 3.0 also adds in DigiCert root certificates to its CA certificates base package, and also brings dozens of patches for security fixes to different packages from Python and PyTorch to Docker and CUPS.
Azure Linux 3.0 continues using a Linux 6.6 LTS kernel by default but via the “kernel-hwe” there is a Linux 6.12 LTS based kernel with currently no option for the new Linux 6.18 LTS kernel.
Downloads and more details on this monthly update to the Azure Linux 3.0 platform can be found via GitHub.
