 ## Overview
 
-CachyOS provides a collection of enhanced Linux kernels designed for improved performance across different workloads. Kernels are built from the [CachyOS Linux](https://github.com/CachyOS/linux) fork (currently based on **Linux 7.0**), which merges topic branches on top of upstream stable releases.

 ## Features
 
-The CachyOS kernel fork merges topic branches into each release. The current **Linux 7.0** base includes the following integrated branches and enhancements.
+The CachyOS kernel fork merges topic branches into each release. The current **Linux 7.1** base integrates fifteen topic branches (`amd-isp4`, `bbr3`, `cachy`, `cgroup-vram`, `drm-fair`, `fixes`, `hdmi`, `lenovo-wmi`, `mglru`, `preempt-ipi`, `sched-cluster`, `snd-codecs`, `t2`, `vesa-dsc-bpp`, and `vmalloc-free`) on top of upstream stable.
 
 ### Performance Optimizations
 
 - **Advanced Compilation**: Highly customizable PKGBUILD with support for both GCC and Clang compilers
-- **Link Time Optimization (LTO)**: Clang Thin LTO enabled by default on the main `linux-cachyos` package
+- **Link Time Optimization (LTO)**: Clang Thin LTO (v12) enabled by default on the main `linux-cachyos` package
 - **Distributed ThinLTO**: Support for distributed Clang ThinLTO builds to speed up kernel compilation
 - **Profile-Guided Optimization**: AutoFDO + Propeller profiling on the default kernel for optimal code generation ([Learn more](https://cachyos.org/blog/2411-kernel-autofdo/))
 - **Kernel Control Flow Integrity (kCFI)**: Available when using LLVM for enhanced security
 - **Timer Frequency Options**: Configurable between 100Hz, 250Hz, 300Hz, 500Hz, 600Hz, 750Hz, and 1000Hz (default: 1000Hz)
 - **Architecture Optimizations**: Support for x86-64-v3, x86-64-v4, and AMD Zen4 specific builds
 - **Compiler Optimizations**: Advanced GCC flags including `-fivopts` and `-fmodulo-sched`
 - **PREEMPT_DYNAMIC**: Runtime-selectable preemption modes (full, lazy, voluntary, none)
+- **vmalloc Optimizations**: Bulk page freeing in `vfree()`, improved `vrealloc()` shrink/grow paths, and optimized contiguous range freeing
 
 ### CPU Enhancements
 
 - **Multiple Schedulers**: BORE, EEVDF, and BMQ schedulers for different workload optimization
-- **[POC Selector](https://github.com/masahitoS/scx_cake)**: Piece-Of-Cake fast idle CPU selector inspired by scx_cake, reducing wakeup latency
+- **[POC Selector](https://github.com/masahitoS/scx_cake) v2.6.2**: Piece-Of-Cake fast idle CPU selector inspired by scx_cake, reducing wakeup latency
+- **Cluster-Aware Scheduling**: Improved load balancing for CPU clusters, including balancing between CPUs of identical capacity on hybrid architectures
+- **Preempt-IPI Optimizations**: Lower-latency SMP/IPI paths with preemption re-enabled before TLB flushes and streamlined `smp_call_function()` handling
 - **CachyOS Sauce**: Custom `CONFIG_CACHY` configuration with scheduler and system tweaks
 - **AMD P-State Enhancements**: Preferred Core support and latest amd-pstate improvements from linux-next
 - **Real-Time Support**: RT kernel builds available with BORE scheduler integration
 - **Low-Latency Optimizations**: Patches for improved responsiveness and reduced jitter
 - **sched/wait LIFO accept()**: Socket accept() processed in LIFO order for better cache efficiency
+- **Wakeup CPU Affinity**: Prefer the previous CPU for task wakeups to improve cache locality
