Anthropic has released Claude Code version 2.1.325, a maintenance update focused on security and infrastructure stability. The most critical change is a fix for a security issue in the decoding of zstd-compressed responses. The release also resolves numerous bugs affecting the Model Context Protocol (MCP), including issues where background tasks would lose connections or fail to reconnect after token refreshes. Additionally, the patch fixes context length errors on third-party gateways and corrects permission handling for artifact tools. These changes aim to reduce session interruptions and improve reliability for enterprise users managing complex agent workflows.

This release quietly introduces Code Mode, an opt-in feature where Claude writes JavaScript to call its own tools, marking a shift toward more autonomous agent-like behavior within the CLI. The update also hardens the plugin ecosystem by enforcing version ranges and adding strict TypeScript type checking for hooks, which should significantly reduce instability from third-party extensions. Beyond these features, the changelog is dominated by critical fixes for authentication drift in background sessions and memory leaks when handling large files, stabilizing the tool for heavy enterprise use.
This release quietly shifts the default Fable model to version 5.2 with a generous 1M context window, making long-context coding significantly more viable without manual configuration. More critically, it addresses several security gaps in MCP OAuth handling and sandbox permission checks that could have exposed sensitive tokens or bypassed safety protocols. The update also stabilizes Remote Control and background agent interactions, fixing issues where sessions would hang or lose state during network interruptions. For developers relying on Claude Code for complex, multi-step workflows, this patch reduces the friction of managing long-running tasks and ensures safer execution environments.
This release targets the persistent performance gap on AMD hardware by optimizing Vulkan Flash Attention specifically for RDNA3 and RDNA4 architectures. The changes include reducing shared memory usage through buffer reuse and fixing critical stability issues like NVIDIA hangs and sparse FA underflow bugs. While there are no new model architectures, these low-level shader optimizations directly translate to faster inference speeds for local users on modern AMD GPUs. It is a quiet but necessary engineering update that tightens the ecosystem for non-NVIDIA accelerators.
This release quietly extends llama.cpp’s hardware support to the latest NVIDIA and AMD stacks. By shipping binaries for CUDA 13.5 and ROCm 10.0, it ensures users on cutting-edge GPUs don't have to compile from source to get performance gains. The Vulkan build also fixes header inclusion issues that previously broke compilation on some Linux distributions. It’s a maintenance update rather than a feature leap, but it keeps the local inference runtime compatible with the fastest consumer and datacenter hardware available today.
This is a routine maintenance release for llama.cpp that quietly extends hardware support to the latest NVIDIA and AMD stacks. By adding CUDA 13.5 and ROCm 10.0 binaries, it ensures local inference remains viable on cutting-edge GPUs without waiting for community forks. The build also includes OpenVINO and SYCL variants, reinforcing its role as the universal runtime for diverse accelerators. While no new model architectures are introduced, this update keeps the toolchain compatible with modern driver ecosystems.
