The new OS release drives major changes in enterprise computing.
Unpacking the Technical Core of Questing Quokka's Security Overhaul
Consequently, the release of Ubuntu 25.10, codenamed "Questing Quokka," marks a critical security milestone. Canonical officially unveiled the operating system on October 9, 2025. This interim release contains major architectural changes designed to pave the way for the next Long-Term Support (LTS) version. Developers worldwide are already adopting the new features in their cutting-edge projects.
Memory Safety and the Rust Revolution in System Utilities
Furthermore, one of the most profound updates involves core system utilities. Canonical officially replaced the traditional C-based `sudo` with sudo-rs. This move drastically improves security by eliminating an entire class of C language vulnerabilities. The project targets memory safety issues that have plagued operating systems for decades. This shift proves that the company places a high priority on user protection and stability. The foundational utilities, known as coreutils, also started their move to a Rust-based implementation in this release. This comprehensive effort strengthens the entire system structure. You can read more about the memory safety push on the Canonical blog.
Key Architectural Stats Driving the Next Enterprise Release
- Linux Kernel 6.17: This new kernel version powers the operating system, delivering enhanced support for new hardware. It notably includes better compatibility for Intel Core Ultra graphics and discrete Arc GPUs.
- Default Wayland and GNOME 49: Ubuntu 25.10 fully deprecates the X11 session for **GNOME 49**, making Wayland the default display server. This release introduces the memory-safe, Rust-built **Ptyxis** (new terminal) and **Loupe** (new image viewer) as default applications. This change is crucial for modern graphical performance and security across sophisticated LLM applications.
- TPM-backed Full Disk Encryption: The installer now includes experimental support for this high-security feature. This innovation utilizes the Trusted Platform Module (TPM) chip found in modern PCs. It automatically unlocks the disk using hardware keys, thereby minimizing manual risk.
- NTS and Post-Quantum Security: Network Time Security (NTS) is now enabled by default using Chrony, providing cryptographic authentication for time synchronization. The kernel also ships with **Post-Quantum Cryptography (PQC)** readiness via updated OpenSSH 10.0 and OpenSSL 3.5.3.
Canonical’s Billion-Dollar Bets: Investment, AI Workloads, and Market Reach
Moreover, Canonical's commercial strategy aligns directly with enterprise demands and market growth statistics. They actively focus their development efforts on areas providing the highest return for their business customers. These strategic investments ensure that Ubuntu maintains its dominant position in key technical sectors. This dedication guarantees platform relevance in rapidly evolving fields like artificial intelligence and cloud infrastructure.
Massive Long-Term Commitment to Core Developer Technology
Subsequently, Canonical announced a significant, long-term commitment to Java and OpenJDK development. This bold move guarantees up to twelve years of security maintenance for OpenJDK 8 on Ubuntu Pro until the year 2034. They promise this same commitment—at least twelve years of support—for **all future OpenJDK Long-Term Support releases**. This massive security deal represents a huge commitment to the enterprise Java ecosystem. Enterprises require this kind of reliable, decade-plus support for mission-critical software. Furthermore, this long-term investment solidifies Ubuntu's reputation as a trustworthy platform for cloud-native applications. This focus on backend infrastructure confirms the company's enterprise-first approach.
Statistical Highlights of AI and Compute Workloads
- Cloud Dominance Metric: Linux now powers 49.2% of all cloud workloads globally as of Q2 2025. This statistic clearly shows the operating system's dominance in IaaS and PaaS layers.
- AI Inference Shift: Conference talks at the Ubuntu Summit 25.10 heavily featured sessions on "Optimizing AI Workloads." This focus reflects the industry-wide pivot from model training to high-volume inference using intelligent systems.
- Market Valuation Trend: The total Linux OS market size is currently valued at around $9.1 billion in 2025. Analysts project this market will grow to $18.73 billion by 2029, indicating rapid enterprise adoption.
The Growing Desktop Foothold and Next-Generation Architectures
However, Canonical’s vision extends well beyond the server and cloud. The Ubuntu Summit 25.10 also showcased significant desktop environment refinements, including the adoption of memory-safe applications like **Ptyxis** and **Loupe**. This commitment targets general users, developers, and designers alike. They seek to increase the platform's overall market penetration in personal computing.
RISC-V, IoT, and New Hardware Compatibility Initiatives
Moreover, Canonical is making crucial investments in emerging hardware platforms. The Questing Quokka release officially adopts the RVA23 profile for RISC-V. This is an important step towards accelerating widespread implementation of the open standard processor architecture. This decision helps establish binary compatibility at the application level. Development sessions at the developer event specifically highlighted support for Qualcomm IoT platforms. Furthermore, this aggressive pursuit of new chip architectures ensures Canonical remains a leader in embedded systems and Internet of Things (IoT) deployment. Edge AI devices, for example, are predominantly driven by Linux, with 71.9% of edge inference workloads running on the OS.
Global Market Share and Developer Adoption Metrics
- Distribution Leadership: Ubuntu maintains its position as the most widely used Linux OS distribution overall, capturing a 33.9% market share. This figure combines server, desktop, and IoT usage globally.
- Developer Preference: A massive 78.5% of developers report using Linux as either their primary or secondary operating system in 2025. This metric highlights the platform's essential role in modern software development for building neural networks and other advanced technologies.
- Desktop Growth: The global Linux desktop market share has continued its steady climb. Current statistics place the desktop market share between 3.7% and 4.35% worldwide, showing consistent annual user growth.
A Forward-Looking Platform Built for Robust Enterprise Systems
Ultimately, the Ubuntu Summit 25.10 and the associated software release reinforce Canonical's focus on security and high-value workloads. The adoption of memory-safe languages, the introduction of NTS and PQC readiness, and the commitment to long-term enterprise Java support are definitive business decisions. These choices benefit not only developers but also large organizations seeking stability. Consequently, the new features ensure Ubuntu remains the premier platform for the next generation of computing workloads.
