0.3.0

Release 0.3.0 🚀

Custom Prefixes for Checkpoint Savers (#125, #127)

You can now configure custom key prefixes for checkpoint and store data, enabling multiple isolated checkpoint savers to coexist in the same Redis instance:

from langgraph.checkpoint.redis import RedisSaver

# Use custom prefixes for isolation
saver = RedisSaver.from_conn_string(
    redis_url,
    checkpoint_prefix="myapp:checkpoints:",
    checkpoint_writes_prefix="myapp:writes:",
    blob_prefix="myapp:blobs:"
)

Bug Fixes

• Pydantic BaseModel Compatibility (#126): Fixed deserialization of Pydantic BaseModel state objects by prioritizing _revive_if_needed over _reviver in the serde chain
• LangChain Message Serialization in Store (#128): RedisStore now properly serializes and deserializes LangChain message objects (HumanMessage, AIMessage, etc.)
• Security Updates: Updated urllib3 and langchain-core to address high-severity vulnerabilities

Compatibility

• Redis-py 7.x Ready: Removed upper bound on redis-py version to allow 7.x when redisvl updates their constraint
• Python 3.13 Support: Added compatibility tests confirming support for Python 3.13

0.1.2

🎉 What's New

Features

• Custom Store Prefixes (#99): Added support for customizable store and vector prefixes, enabling multiple isolated stores in the same Redis instance
  store = RedisStore.from_conn_string(
  redis_url,
  store_prefix="myapp_store",
  vector_prefix="myapp_vectors"
  )

Bug Fixes

• Type Compatibility: Resolved mypy type errors with redis-py 6.3.0+ stricter JsonType requirements for JSONCommands.set()
• Runtime Warnings: Fixed deprecation warning for datetime.utcnow() (now uses datetime.now(timezone.utc))
• Async Client Info: Fixed RuntimeWarning about unawaited coroutines in set_client_info() by moving call to concrete implementations
• Test Accuracy (#87): Removed incorrect skip decorator from test_async_alist_with_deserialization - the deserialization feature was already implemented

Dependencies

• redisvl: Upgraded from 0.8.0 → 0.9.1
  • Fixes version reporting (version now correctly reports "0.9.1")
  • Includes fix for ClusterPipeline AttributeError (#96)
• redis: Constraint updated from ^6.2.0 to >=5.2.1,<7.0.0 to align with documentation

Testing

• Regression Tests (#96): Added comprehensive test suite for cluster mode AttributeError to prevent future regressions
• Custom Prefix Tests (#99): Added 9 tests covering default prefixes, custom prefixes, isolation, and backward compatibility

🔄 Upgrade Notes

This release is fully backward compatible. The default store prefixes ("store" and "store_vectors") remain unchanged, so existing deployments will continue to work without modifications.
