Introduction
The December 2, 2025, release of FreeBSD 15.0 started a new era for the operating system. It brought many enhancements across its entire stack. As a strong and reliable choice for servers, workstations, and embedded systems, FreeBSD keeps evolving. It incorporates modern features while staying committed to stability and performance. This FreeBSD 15 review will examine the most important changes, from low-level system optimizations to user-facing improvements. This will give you a clear understanding of what this major update offers.
Key New Features and Improvements in FreeBSD 15
FreeBSD 15.0-RELEASE includes significant updates that affect almost every part of the system. Here is a breakdown of the most notable additions and enhancements this FreeBSD 15 review covers:
Architectural Changes in FreeBSD 15
One major change in FreeBSD 15.0 is the end of 32-bit support for x86 and POWER architectures. ARM-v7 support remains, but the OS now mostly focuses on five CPU architectures: x86-64, AArch64 (Tier-1), and armv7, powerpc64le, and riscv64 (Tier-2). This smart move helps streamline development and optimize resource use for modern hardware.
Base System Management (pkgbase)
A highly anticipated change is the introduction of pkgbase. This new method for installing and managing the base operating system uses the familiar pkg(8) package manager. Although it is a technology preview in 15.0, pkgbase promises to simplify system updates, make minimal installations easier, and bring FreeBSD closer to Linux distributions’ package management. This is a big step towards more flexible system administration.
Build Process Enhancements
FreeBSD 15.0 brings important improvements to the build process. All release artifacts can now be built without needing root privileges. This is a welcome change for developers and those focused on secure build environments. Also, the release supports reproducible builds, which makes the software supply chain more transparent and trustworthy.
Kernel and Core System Updates
The kernel and core system components have received considerable attention in FreeBSD 15:
- A native
inotifyimplementation has been added. This simplifies directory watching and makes porting software from Linux environments easier. - The kernel now includes an extended error facility. It provides more detailed error information, including string descriptions and source code locations, which helps with debugging.
- Local (UNIX domain) sockets have been re-organized. This results in increased throughput and reduced latency for communication between processes.
Software Updates in FreeBSD 15
Many important software components have been updated to their latest stable versions. This ensures users get the newest features and security patches:
- OpenZFS has been updated to version 2.4.0-rc4. This brings the latest in storage management.
- OpenSSL is now at the latest long-term support (LTS) version 3.5.4. It includes support for QUIC and standardized quantum-resistant algorithms (ML-KEM, ML-DSA, SLH-DSA), which improves cryptographic security.
- OpenSSH has been updated to version 10.0p2. It features quantum-resistant key agreement by default for more secure remote connections.
- MIT KRB5 1.22.1 Kerberos replaces Heimdal 1.5.2 as the default Kerberos implementation.
- Updates also include various utilities and libraries such as
awk,mandoc,jemalloc,bmake,sendmail,bc,libarchive,llvm,tcpdump, andunbound.
Hardware Support and Networking Enhancements
FreeBSD 15.0 offers important improvements for desktop and laptop users, making it a better choice for daily use. These include better WiFi support, updated graphics drivers, and key fixes for suspend/resume functions. Networking also saw updates, like support for new devices and TCP improvements such as inline IPsec offload for smart NICs. The rtw88(4) and rtw89(4) drivers are updated to Linux v6.17, further expanding hardware compatibility.
Cloud and Containerization
The new release also focuses on cloud environments and containers. FreeBSD “base” EC2 images now start up to 76% faster, especially on arm64 instances. Smaller EC2 images are also available for more efficient deployments. Furthermore, OCI container support, including Podman and Linux containers, has improved. This simplifies running Docker commands and tools within FreeBSD environments.
User Experience Improvements
Refinements have been made to the user experience, particularly for desktop users. The Lumina desktop environment has received various improvements. It now includes a file manager, text editor, and PDF viewer. Setting up a desktop environment is also easier compared to previous major releases, which lowers the barrier for new users.
FreeBSD 15 Review: General Impression
Overall, FreeBSD 15.0 is a major update. It shows an important evolution in its construction model. Reviewers describe it as a solid, general-purpose operating system and a “workhorse” known for its reliability and detailed documentation. While it might not attract users looking for cutting-edge desktop technology or a quick desktop setup, it consistently provides a powerful and efficient experience for those who value its Unix-like philosophy.
FreeBSD 15 Performance Benchmarks
Comparisons with various Linux distributions show mixed performance results. FreeBSD 15.0 demonstrates strong concurrency in CPU tests and excellent disk performance in some benchmarks. However, memory read/write operations performed poorly in others. This points to specific areas for optimization and future enhancements.
Conclusion
FreeBSD 15.0-RELEASE is a significant update. It strengthens its position as a robust and adaptable operating system. The introduction of pkgbase, major architectural changes, and continuous improvements to its core system, software, and hardware support together make this release a strong choice. Whether for server deployments, network infrastructure, or as a powerful development platform, FreeBSD 15.0 provides a stable, efficient, and forward-looking foundation. This FreeBSD 15 review highlights a release that, while perhaps not revolutionary for every user, solidly builds upon FreeBSD’s strengths and points towards an exciting future.
