langgraph sdk==0.3.15 released
LangGraph SDK 0.3.15 adds metadata filtering to cron search/count, making it easier for agent builders to target and manage scheduled jobs by metadata, and it bumps core packages including `langchain-core` to 1.4.0, `langgraph` to 1.2.1, and promotes alpha packages to official versions. It also fixes a concrete SDK bug by percent-encoding caller-supplied identifiers in URL paths, which should prevent malformed requests and improve reliability when IDs contain special characters.
