Linus Torvalds, the father of the Linux kernel, officially announced that the stable Linux 7.1 kernel has been released and will be integrated and tested by major distributions and pushed to end users through system updates. Stable channel users of some distributions (such as Debian) may not receive this version for a long time, or even skip it entirely; while faster-paced distributions such as Fedora are expected to provide users with 7.1 kernel updates in the near future.
With Linux 7.1 being released on time as planned, the merge window for the next version of Linux 7.2 has opened, allowing kernel contributors to start submitting patches for major new features that have been prepared over the past two months. Torvalds reminded that he is currently on a business trip and will be in different time zones with limited network conditions, which may have a certain impact on the processing rhythm during the merger window. He said that he had grabbed a batch of early merge requests in advance to process related work offline, but he still did not rule out the possibility of travel interfering with the rhythm. Although he has seriously considered extending this development cycle, he has not yet made a decision to extend it, and admitted that he may "some regret" this decision in the future.
In the last week of development before Linux 7.1 is officially released, Torvalds said there haven't been any major or alarming changes. The work of the past week has mainly focused on smaller but widely distributed driver updates, covering multiple subsystems such as GPU, network and audio. It also includes network stack fixes, trace tooling fixes, and some miscellaneous minor bug fixes. The official shortlog lists a large number of fixes for driver defects, memory leaks, I/O and USB, network and RDMA, DRM/graphics subsystem, as well as toolchain and verification processes.
In terms of specific repairs, this version fixes a number of USB-related heap overflow and buffer overflow issues, and fixes multiple use-after-free, memory leaks and reference counting (refcount) errors in i2c, zram, gpio, net and other subsystems. In terms of graphics, this update brings fixes and enhancements to graphics card drivers such as amdgpu, i915, and virtio. It also makes targeted adjustments to virtualization and hypervisor-related components such as mshv, vmbus, and Hyper-V.
According to a summary by third-party Linux technology site Phoronix, users who upgrade to Linux 7.1 should focus on key changes such as the new NTFS driver, FRED support for Intel Panther Lake and subsequent processors, improvements to improve Intel Arc Battlemage GPU graphics performance, and optimizations for older AMD Radeon graphics cards. The rewritten NTFS driver is expected to bring greater stability and efficiency to scenarios where this file system is used, while optimization for new-generation CPUs and GPUs will further unleash the performance potential of future hardware platforms in the Linux environment.
For ordinary desktop users, if the Linux system they are currently using runs stably under the existing kernel version and there are no obvious compatibility or performance issues, then there is no need to rush to proactively upgrade to Linux 7.1. You can wait for the distribution to push updates through the official warehouse. However, if you have tried to install Linux on some hardware devices before and encountered problems such as incomplete drivers and the device not working properly, you can consider trying again after the introduction of Linux 7.1 in the relevant distribution. With its enhanced hardware support and driver repairs, the system is expected to achieve better operating results on these machines.
