Changelog

Notable changes to AgentSeek API are documented in this file.

Unreleased

0.3.1 - 2026-09-03

Highlights

  • Upgraded both the base and embedded langchain-oceanbase dependency pins to 0.6.3, with the resolved embedded seekdb stack at pylibseekdb 1.4.0, pyobvector 0.2.29, and pyseekdb 1.4.0.post1.
  • Synchronized package metadata, generated container runtime artifacts, attestations, scripts, fixtures, and runtime labels at 0.3.1.
  • Restricted the supported Python range to >=3.12,<3.14 and made generated runtime verification reject unsupported Python versions.
  • Normalized current human-facing documentation and runtime prose to the lowercase seekdb product spelling.

Upgrade notes

  • No API or schema migration is required for this release.

0.3.0 - 2026-08-20

Highlights

  • Added the explicit preloaded-v1 container environment contract so the host remains the single owner of application environment resolution.
  • Generated containers install and attest the exact agentseek-api[embedded]==0.3.0 runtime independently of project dependencies.
  • Hardened Docker, Compose, and build-context boundaries so application values are carried only to the declared runtime target and credential-bearing source files are excluded from image inputs.
  • Defined compatible custom-image labels and runtime-manifest checks for preloaded-v1 launches.

Upgrade notes

  • Container projects that pin agentseek-api==0.2.2, or otherwise exclude 0.3.0, must update their dependency constraint before using generated images.
  • Custom images must publish the preloaded-v1 environment-contract, runtime manifest, distribution, and version labels; older images must keep using the older launcher until migrated.
  • dockerfile now writes a complete build-bundle directory. Declare only reviewed project paths with build_include; credentialed pip_config_file input is delivered as a BuildKit secret rather than copied into the bundle.
  • Container application values cross only an explicit runtime boundary: --pass-env selects the direct Docker carrier, while compose_env and --compose-pass-env select the private Compose dotenv carrier. All are trusted-input declarations and none authorize values to enter the build.
  • Custom images must provide the exact org.agentseek.environment-contract, org.agentseek.runtime-manifest, org.agentseek.runtime-distribution, and org.agentseek.runtime-version labels and matching manifest/runtime state. There is no legacy-image fallback.
  • Release Train A shipped API 0.2.3, templates 0.1.3, and AgentSeek 0.1.3. The planned Train B template/catalog release is 0.1.4. The separate planned AgentSeek release is also 0.1.4; both follow their shipped 0.1.3 releases and remain separate release gates.

0.2.3 - 2026-08-17

Fixed

  • When METADATA_DB_BACKEND=sqlite, store completed-run snapshots in the configured SQLite metadata database instead of constructing an OceanBase saver and attempting a MySQL-family connection.

Upgrade notes

  • No manual schema or configuration migration is required. The agentseek_checkpoints table is created idempotently at startup.
  • This fix covers completed-run snapshots only. LangGraph checkpoint state remains in memory when the metadata backend is SQLite.

0.2.2 - 2026-08-16

Highlights

  • Added bounded parallel Redis job execution within a worker process. Set WORKER_CONCURRENT_JOBS to control the limit; the default is 10.
  • Aligned assistant and run config.configurable / context handling with the LangGraph API contract, including assistant defaults and legacy configurable access for graphs without a context schema.
  • Defined one deterministic environment-ownership contract for the dev, serve, worker, and scheduler host runtimes.

Fixed

  • Made Redis job acknowledgement conditional on ownership of the active worker lease, and stopped scheduling safely when a job fails or the lease is lost.
  • Rejected client requests that provide both non-empty config.configurable and context, mirrored either input into the other representation, and merged assistant configuration into run configuration without discarding nested defaults.
  • Made inherited host environment keys, including explicit empty strings, authoritative over config and CLI dotenv sources.
  • Parsed each dotenv source independently with strict malformed-file handling, and distinguished valueless KEY from explicit empty KEY=.
  • Started worker and scheduler in fresh child processes so their settings are built after the resolved environment is installed.
  • Added bounded signal forwarding and descendant-process cleanup for serve, worker, and scheduler across supported platforms.
  • Kept version, help, and Dockerfile rendering independent of runtime settings validation.
  • Fell back to an ASCII CLI banner when a legacy Windows console cannot encode the Unicode banner.

Upgrade notes

  • Redis workers now execute up to 10 jobs concurrently by default. Set WORKER_CONCURRENT_JOBS=1 to retain the previous serial behavior.
  • Clients must not send both non-empty config.configurable and context in one assistant or run request; such requests now return HTTP 400. Prefer context for new integrations.
  • For dev, serve, worker, and scheduler, dotenv interpolation is supported only against the inherited environment and earlier bindings in the same physical file.
  • For those host runtime commands, missing, malformed, and non-UTF-8 dotenv sources fail closed with status 2 before a runtime child starts.
  • Dependency resolution now requires SQLAlchemy 2.0.12 or newer, LangGraph 1.0.6 or newer, LangChain Core 1.2.5 or newer, and MCP 1.27.1 through the 1.x series. python-dotenv 1.0 through 1.2 is now a direct dependency.

0.2.1 - 2026-07-14

Fixed

  • Preserved empty JSON arrays in Redis thread-stream events by avoiding a Lua cjson decode/encode round trip, while keeping generated envelope fields authoritative.
  • Mirrored completed tool, human, and system messages to messages-tuple when requested so LangGraph SDK clients receive tool results before final-answer streaming completes.

Upgrade notes

  • No schema or configuration migration is required from 0.2.0.

0.2.0 - 2026-07-12

Highlights

  • Expanded the Crons API to align its request, response, filtering, sorting, selection, and lifecycle behavior with the LangGraph Platform contract.
  • Moved Redis-worker run and protocol event persistence from SQL to bounded Redis Streams, removing metadata-database writes from the streaming hot path.
  • Preserved UTF-8 output across SSE, wait, and A2A JSON responses while keeping active thread event retention bounded without dropping live events.
  • Upgraded checkpoint integration to langchain-oceanbase 0.6.0.

Upgrade notes

  • Drain active Redis-worker runs before upgrading. Stream-event rows written to SQL by earlier versions are not imported into Redis Streams.
  • Redis stream replay is bounded by REDIS_STREAM_MAXLEN and REDIS_STREAM_TTL_SECONDS; review these settings for long-running workloads.
