While some business decisions surrounding the RHEL ecosystem continue to generate discussion, AlmaLinux is stepping on the gas with its release 9.7 'Moss Jungle Cat' (after the AlmaLinux 9.6 release). Far from being a mere clone, this edition shows a maturity that already competes in performance and reliability. with any enterprise distribution, maintaining the 1:1 binary compatibility that organizations value so much.
This release is built from the same sources as RHEL 9.7, yes, but what's interesting is the set of improvements, tools, and processes that AlmaLinux integrates from Alma Linux 9.2 and makes it available to anyone free of charge. From a modern toolchain to enhanced security and expanded support for containers and cloudThe package encourages both starting from scratch and migrating existing infrastructures without any problems.
What AlmaLinux 9.7 'Moss Jungle Cat' offers
The core of the system remains on kernel 5.14, a stable and thoroughly tested point for production environments. The key promise remains: 1:1 binary compatibility with Red Hat Enterprise Linux 9.7with the advantage of an active community, a solid update schedule, and no license costs or vendor lock-in.
The AlmaLinux Foundation has announced the general availability (GA) of this version, with ISOs ready on the official mirrors and torrents to speed up downloads. The artifacts cover all common enterprise architectures (x86_64, AArch64, ppc64le and s390x)In addition, cloud, container, and live image builds are launched as soon as the public repository is ready.
Downloads, torrents and images
You can now obtain the installation ISOs from the mirrors, and if you prefer P2P, Torrents are also available to speed up and distribute the load.Cloud images (for major providers), containers, and live images are released as soon as the build pipelines are complete, so if you don't see them yet, they'll be arriving soon.
For finer details and comprehensive changes, the AlmaLinux wiki hosts the 9.7 release notes. If you need a canonical document for compliance or audits, the project's Release Notes are your reference., with updated package listings, module flows, and security policies.
Toolchain and module flows: unconstrained development
Version 9.7 stands out for bringing a modern build chain that allows you to compile and run current software without relying on third-party repositories. GCC 15, LLVM 20.1.8, Rust 1.88.0 and Go 1.24 They form a development base ready for high-performance workloads and cloud-native applications.
- GNU C Library 2.34 y GNU Binutils 2.44 They fine-tune compatibility and runtime performance.
- Compilation instrumentation benefits from Annobin 12.98 for metadata and security checks.
- Among the updated module flows, the following stand out: Node.js 24 y SWIG 4.3, opening the door to web stacks and links between more current languages.
- The Microsoft ecosystem is also covered: .NET 10.0 It lands with stable support and easier deployment.
In the user and software development section, there are significant increases: GIMP 3.0.4, Mesa 25.0.7, Samba 4.22.4 and Git-LFS 3.6.1, with improvements in compatibility, graphics, and workflows with large repositories.
Debugging, tracing, and performance: less time hunting bugs
Anyone who has had to diagnose crashes or memory leaks knows that every version of the tools matters. In AlmaLinux 9.7, GDB 16.3 It improves support for complex applications and multithreaded scenarios, while Valgrind 3.25.1 It refines the detection of memory leaks, invalid accesses, and memory usage profiles.
- System Tap 5.3 y Dyninst 13.0.0 They expand dynamic instrumentation options for analysis without restarting services.
- elfutils 0.193 y libabigail 2.8 They help navigate symbols, ABIs, and binary changes more accurately.
- For observability, Bpftrace 0.23.5 y PCP 6.3.7 They offer real-time inspection and time series performance data.
- The registration layer is strengthened with rsyslog 8.2506.0And for dashboards we continue to rely on Graphana 10.2.6.
In real-world projects, upgrading to a newer version of this suite of utilities can mean hours of diagnostics saved, fewer downtimes, and greater confidence. If you work in SRE, performance engineering, or production support, you'll notice the benefit on a daily basis..
Networking and security in AlmaLinux 9.7: thinking about business and the post-quantum future
In networking, the 9.7 level up with Network Manager 1.54This simplifies advanced topologies, bondings, and VLANs, and with Ethtool 6.15 to profile and adjust cards with greater granularity. iproute 6.14.0 It completes the trio for policies, advanced routing, and queues.
Safety receives special attention. Open SSL 3.5 It introduces multiple improvements and, most notably, a cryptographic 'PQ' sub-policy to enable post-quantum algorithms (PQC) in a controlled manner at the system level. In addition, there are key updates such as SSSD 2.9.7, Keylime 7.12.1 for platform integrity with TPM, and SELinux-policy 38.1.65, which reinforces confinement and rules.
All of this translates into a platform prepared to meet today's stricter compliance requirements, and to anticipate tomorrow's post-quantum riskwithout having to reinvent the security stack in the medium term.
Containers, cloud and virtualization
For those working with microservices and CI/CD, the container base is up to date: Podman 5.6.0 y Buildah 1.41.4 They simplify daemon-free construction and execution, with improvements in security, compatibility, and performance. It's a platform ready for modern pipelines and deployments on Kubernetes or OpenShift without external dependencies.
AlmaLinux publishes official container and cloud images as soon as the public repository is ready, so the time-to-cloud is very short. If you work with heterogeneous or multi-cloud architectures, having aligned artifacts between on-premises and cloud reduces friction. when moving loads.
Binary compatibility and governance model
1:1 compatibility with RHEL is the core of the project. That means that what works on RHEL 9.7 will work on AlmaLinux 9.7 Without recompilation, a crucial guarantee for ISVs, hardware vendors, and operations teams with demanding SLAs.
Furthermore, the project is community-based and open source, with a focus on stability and reproducibility. The community is active, responds quickly to incidents, and collaborates on testing.This is noticeable in the overall quality and the frequency of updates.
Migration and upgrades: from scare to routine
If you come from 8.5 CentOSThe migration to AlmaLinux is designed to be straightforward using official deployment tools. The goal is to minimize the impact and preserve configurations, repos and services with the least possible downtime.
For those still using CentOS 7 or need to upgrade between major versions, the community maintains Elevatewhich allows for 'on-site' updates with verified control and paths. It is the recommended way to modernize without reinstalling from scratch. and maintain operational continuity.
Recent migration experiences provide interesting data in production. A 15–20% improvement has been observed on Java/Tomcat application servers performance improvements, lower memory consumption at the same load, and more stable boot times.
On development workstations, Compilations are faster with GCC 15 and debugging is improved with GDB 16.3For the teams, the change is transparent: same key tools, but more modern and refined.
Quick comparison with alternatives
Choosing an enterprise distribution involves evaluating community, support, and governance model. Compared to Rocky Linux, AlmaLinux is very similar in technical aspects., with differences in how the community is organized and makes decisions.
If you look at Oracle Linux, Commercial support can be a plusHowever, it is worth considering a possible vendor lock-in and its medium-term implications. Ubuntu Server It offers a more 'modern' stack in some areas, but often It is less stable for legacy workloads that depend on ABI, API, and predictable lifecycles.
Architectures supported in AlmaLinux 9.7
This version retains the four key architectures: x86_64 for the majority of servers and workstations; AArch64, increasingly present in cloud and high-performance ARM; ppc64le for enterprise environments that require big endian lite; and s390x for mainframes where stability, I/O and security are non-negotiable.
Deployment recommendations
For new installations, strip of official ISOswhich include accumulated patches and regression tests passed by the community. If the target is containers or lightweight VMs, the minimalist profile It will give you smaller images and less attack surface.
Don't forget to adjust the new ones kernel tunables depending on your load (I/O intensive, low latency, shared memory, etc.). In environments with compliance requirements, activate the 'PQ' cryptographic subpolicy only where applicable and validate compatibility with your clients and services.
If you're already on the 9.x branch, The update process is straightforward And it works well. Configurations are preserved, and if any problems arise, reverting is simple as long as you have snapshots, backups, or package transactions ready.
Looking at the whole picture, this 9.7 combines enterprise compatibility, a modern toolchain, powerful observability, and a clear focus on security (including post-quantum readiness). If your goal is stability without license fees and with an engaged community, here's a very solid foundation. for critical workloads, cloud-native environments, and demanding development teams.
