What shipped

Python SDK v2.2.1 fixes add() to report only records the vector store actually inserted, raising an error if none succeed. Release

Python SDK v2.2.0 adds User Profiles with get_profile(), generate_profile(), get_profile_settings(), update_profile_settings(), sample_profiles(), and get_profile_job(). Release
TurbopufferDB vector store now respects distance_metric in search score calculation instead of always using cosine formula. Pull request #6559
Memory and AsyncMemory context-manager protocol restored to support with...as syntax. Pull request #7354
TypeScript SDK no longer forces pg as a required peer dependency, making it optional for hosted MemoryClient users. Pull request #7450
Python SDK dev tooling (ruff, isort, pre-commit) now wired into hatch environments so setup works on fresh clone. Pull request #6684

Why it matters

Two SDK versions ship with User Profiles—a structured JSON summary shaped by per-project schema that stays current—plus fixes for config injection, vector store scoring across distance metrics, and the context-manager protocol. Multiple vector stores and LLM providers also get fixes for filter operators and content parsing.
