Docker brings Sandbox Kit Spec to the CNCF — Docker open-sourced the Sandbox Kit Spec under Apache 2.0 and is bringing it to CNCF governance. A Kit is an ordinary OCI image that packages an AI agent, its tools, and a typed list of hosts, credentials, and volumes it may reach, so pinning the image pins both the agent and its permission requests.

StreamNative open-sources Ursa, UFK, and the Lakestream API — StreamNative released Ursa 1.0, Ursa for Apache Kafka (UFK), and the Lakestream API and specification under Apache 2.0. Ursa turns object storage into stream storage with diskless Kafka topics and a stream materialization path into lakehouse tables; Pulsar support is planned next.

Transformers now runs llama.cpp GGUF quants — Hugging Face added efficient GGUF loading in transformers via from_pretrained, reusing ggml Metal kernels through the kernels library. The initial packed path targets Apple Silicon with Qwen3.5, with OpenAI-compatible serving through transformers serve. Hugging Face · cmum9u8x4c10a586c0e306c78

llama.cpp 0.5.0 expands backends and server ops — The v0.5.0 release ships CUDA conv2d acceleration, Metal MoE/SSM fusion, multi-address HTTP binding, broader model conversion support including MiMo-V2.6 and HunyuanOCR, and ggml 0.25.0 backend improvements. GitHub · cmum9u8x52f319147bbe46849

SkyWalking AI Sessionizer captures LangChain and LangGraph agents — Apache SkyWalking showed how Sessionizer 0.5.0 can assemble and replay LangChain/LangGraph conversations through a langsmith-ingest adapter without changing the application, recording tool side effects and mid-turn failures for agent observability.

Apache Parquet adds ALP floating-point encoding — Parquet format 2.14.0 introduces Adaptive Lossless floating-Point (ALP) encoding for FLOAT/DOUBLE decimal-like data, aiming for zstd-like ratios with much faster decompression, random access, and SIMD/GPU-friendly decoding; Rust parquet 60.0.0 already supports it.

Sley 2.0: machine-native programming for AI agents — Greyforge Labs released Sley 2.0 under Apache-2.0 as a clean break from 1.x: programs are typed semantic graphs that agents mutate through validated proposals rather than text patches, with a deterministic kernel, attested Linux binaries, and an honest non-GA acceptance ledger.

Cortex open-sources engrams for cloud coding agents — Cortex released engrams, an open-source platform to run Claude Code, Codex, or custom agents in your own cloud on Firecracker/KVM or Apple Virtualization, with automations for dependency and CVE upgrades, memory hot spots, and bug triage still at 0.x.

StreamNative open-sources Streaming Proof — Following Ursa, StreamNative published Streaming Proof under Apache 2.0: a long-running correctness harness for Kafka-compatible, Pulsar, and MQTT systems that checks delivery, per-key ordering, and exactly-once under chaos, with TLA+ specs for its own checkers.
