​
Agent Journal 1.6.0

First-class capture primitives + a cost-metering correction. Slice 1 of the cross-repo journal-capture contract ships the §4 primitives downstream repos import, alongside a fix that roughly halves a long-run cost-accounting error.
  • New primitives: PhaseCapture.stepCosts(), JournalSteps.fromEvents(), a production fail-loud RunRecorder, and per-turn usage in the immutable log
  • Cost-metering fix: the headline LLMCallEvent.tokenUsage is now the cost-bearing Σ-per-turn-by-type aggregate (incl. cache) instead of the last-ResultMessage snapshot, which under-counted ~2× on long runs — same field, corrected value, no schema change
  • A per-file schemaVersion header on events.jsonl / analysis.jsonl (loaders skip it)
  • Additive on the frozen capture contract — a 1.5.0 consumer keeps working; 482 tests green

​
AgentWorks BOM 1.13.0

Repins Agent Journal to 1.6.0. A focused, journal-only bump behind the usual gate.
  • All three journal artifacts (journal-core, claude-code-capture, gemini-cli-capture) → 1.6.0; every other member unchanged
  • Published behind the CI-enforced bom-verification gate (plain / Boot 3.5 / Boot 4), re-verified from Central post-publish

​
Agent Journal 1.5.0

First-class Gemini CLI capture. The new gemini-cli-capture module projects Gemini runs into the same portable trace + cost schema as Claude, so one analysis layer reads both runtimes — plus per-step cost attribution.
  • New gemini-cli-capture module — cross-runtime capture into one trace + cost format
  • Per-step cost attribution (StepCostEvent, analysis.jsonl sidecar); portable TraceWriter moved into journal-core

​
AgentWorks BOM 1.10.0 → 1.12.0

CVE remediation locked in, then the Gemini capture cut. Three BOM releases close out the Spring AI 2.0 security work and add the new journal member.
  • 1.10.0 / 1.11.0 (Jun 15): repin the source-fixed members to lock in the CVE remediation — claude-code-sdk 1.4.0, workflow 0.10.0, Spring AI BOM 2.0.0 backstop
  • 1.12.0 (Jun 17): repin Agent Journal to 1.5.0 and add gemini-cli-capture as a managed member — the first BOM release through the CI-gated release.yml (pre-publish gate + post-publish FINAL_PROOF)

Week of June 8, 2026

​
AgentWorks BOM 1.9.0

Suite-wide security release: Spring AI 2.0 GA convergence, four CVEs cleared. The BOM moves the suite onto Spring AI 2.0.0 GA and Spring Boot 4.0.7, and adds Jackson 3 and Reactor management so consumers resolve a vulnerability-free, converged dependency set — proven end-to-end against the published artifacts by the bom-verification gate.
  • Clears Spring Boot CVE-2026-40976 (CRITICAL) and -40973 (HIGH), Spring AI CVE-2026-41712 (HIGH), and Jackson CVE-2026-29062 (HIGH)
  • New managed import tools.jackson:jackson-bom 3.1.4 — converges Spring AI 2.0’s transitive Jackson 3 (its jsonschema-generator pulls jackson-core 3.0.3) up to a CVE-clear 3.1.4
  • New managed reactor-core 3.8.6 — reconciles claude-code-sdk’s 3.8.5 with Spring AI 2.0’s 3.8.6, a RequireUpperBoundDeps break the gate caught
  • Preceded by 1.8.0 (Jun 11), which cleared the long-deferred ACP bump to 0.14.0
  • Version Table | Source

​
Agent Client 0.22.0

Spring AI 2.0.0 GA + Spring Boot 4.0.7. The upgrade behind BOM 1.9.0 — primarily a security and dependency release, with one user-facing behavior change.
  • spring-ai 2.0.0-M2 → 2.0.0 GA and spring-boot 4.0.1 → 4.0.7, clearing the transitive Boot / Spring AI CVEs above
  • Spring AI 2.0 GA moved to Jackson 3, so agent-model, agent-claude, agent-codex, and agent-client-core now declare their Jackson 2 usage explicitly (governed by jackson-bom 2.21.2)
  • Default Gemini model upgraded to gemini-3.5-flash; override with agent-client.gemini.model

​
AgentWorks BOM 1.6.0

The bom-verification quality gate lands, with Jackson 2.21.2 convergence. The largest coordinated release of the week — nearly every member moved — and the first to publish behind an automated gate that proves consumers get a single, converged dependency set.
  • New bom-verification/ harness: plain, Spring Boot 3.5, and Spring Boot 4 consumer scenarios with a JacksonConvergenceTest and the enforcer RequireUpperBoundDeps rule; releases now publish only behind a green gate
  • Imports jackson-bom 2.21.2, converging every member and shielding consumers from stray third-party Jackson transitives
  • The gate is load-bearing — re-running it against 1.5.0 fails on the exact Jackson divergence 1.6.0 fixes
  • Bookended by 1.5.0 (Jun 4, a managed test stack — Mockito / JUnit / AssertJ / Byte Buddy) and 1.7.0 (Jun 7, agent-client 0.21.0)
  • Coordinated bump: claude-code-sdk 1.3.0, agent-client / agent-starter 0.20.0, agent-workflow 0.9.0, agent-judge 0.12.0, agent-memory 0.2.0, agent-journal 1.4.0, agent-hooks 0.6.3, agent-sandbox 0.9.3, agent-bench 0.4.0, experiment-core 0.5.0

​
Agent Client 0.21.0

Portable reasoning-effort control across providers. A new provider-agnostic effort option (low / medium / high), with provider-native overrides — and the Provider Parity TCK now actually runs (it had been reporting green without ever executing).
  • AgentOptions.getEffort() — the cross-provider low/medium/high intersection, covered by the TCK
  • Provider-native overrides win when set: Claude ClaudeAgentOptions.effort (→ --effort), Codex CodexAgentOptions.reasoningEffort up to xhigh
  • 0.20.0 (Jun 6) shipped first: Claude trace content modes — traceContentMode(FULL | TRUNCATED | LENGTHS) — and automatic session-transcript archival, powered by agent-journal’s TraceWriter v2
  • Portable Options | Source

​
Claude Agent SDK 1.3.0

Aligned to Claude CLI 2.1.162, with a lossless rawJson escape hatch. A compatibility-and-hardening release that pins the wire contract and exposes wire fields the typed API doesn’t model yet.
  • ParsedMessage.RegularMessage gains a rawJson component carrying the exact stdout line each message was parsed from — backward compatible
  • All six HookInput subtypes now ignore unknown properties, fixing a hook hang under CLI 2.1.162’s added PostToolUse fields
  • New WireFixtureTest pins parsing against real 2.1.162 stream-json fixtures
  • Project | Source

​
Agent Workflow 0.9.0

A tool-agnostic Question / Option callback record. The AgentCallback.onQuestion SPI no longer leaks a tool-library type, and the judge integration completes its move to the io.github.markpollack namespace.
  • New workflow.callback.Question record (with nested Option) owned by workflow-api, replacing the leaked AskUserQuestionTool.Question; the spring-ai-agent-utils dependency drops out of workflow-api
  • Judge integration migrated to io.github.markpollack.judge (agent-judge 0.12.0) across JudgeGate, TieredGate, and the jury loops
  • Agent Loop | Source

​
Agent Client 0.19.0

JSONL trace file support. ClaudeAgentModel now writes durable trace files during agent execution — tool calls, thinking blocks, text, and result metrics, flushed per event. Set traceDir on the builder or agent-client.claude.trace-dir in Spring Boot config. Each invocation writes one uniquely-named JSONL file, and the path is exposed via providerFields.get("tracePath").
  • TraceTarget record pairs run ID with trace file path
  • Fail-fast on invalid trace directory (before client setup)
  • Full UUID in filenames for collision safety
  • Claude Reference | Source

​
Agent Workflow 0.8.0

Trace file capture through the workflow journal. AgentClientStep propagates trace paths from the agent model into StepTransition and journal events. Every tool call in a multi-step workflow is now traceable back to a specific JSONL file.
  • ExecutionResult(text, tracePath) — new return type from AgentClient.executeForResult()
  • AgentContext.TRACE_PATH — well-known context key, cleared per step
  • JdbcTraceRecorder — trace_path column in step_transitions table
  • What’s New | Trace Capture Guide | Source

​
ACP Java SDK 0.12.0

7 new protocol methods. Session lifecycle (list, close, resume) is now stable. Elicitation, fork, and config options land as unstable with the new @UnstableAcpApi marker.

​
AgentWorks BOM 1.2.0

Coordinated version bump: agent-client 0.19.0, agent-workflow 0.8.0, agent-journal 1.2.0, ACP Java SDK 0.12.0, and all other managed artifacts.

​
Week of May 19, 2026

​
Agent Workflow 0.7.0

Managed Agents as a step runtime. ManagedAgentStep delegates workflow steps to Anthropic’s Managed Agents API. The workflow graph stays in charge — specific steps run in Anthropic’s cloud sandbox.

​
Agent Client 0.18.0

Migration to markpollack org. Package rename from org.springaicommunity.agents to io.github.markpollack, BSL license, standalone POM.
