# Release Notes
- v4.7.2(Aug 6,2026)
  - Fixed a thread leak in the file transfer agent by properly shutting down ThreadPoolExecutors after PUT/GET transfers (SNOW-3556240, #2878).
  - Fixed `split_statements` treating `//` as SQL instead of a line comment, which could merge multiple statements when a `//` comment contained an apostrophe (SNOW-3772985).
  - Fixed large-file PUT uploads to internal Azure stages failing against the Azure 50,000-block-per-blob limit. The Azure multipart chunk size is now scaled up dynamically for very large files (mirroring the existing S3 behavior), and the default Azure chunk size was raised from 4 MB to 8 MB (consistent with S3) for better throughput (SNOW-3839943).
  - Fixed OAuth cached-credential connections failing with `250001 Invalid OAuth access token` when the cached token was invalid (GS code `390303`); the connector now...

## AI interpretation — verify before relying

A Python DB API 2.0-compliant connector for Snowflake cloud data warehouse, enabling SQL queries and data operations against Snowflake accounts from Python applications.

Verdict: Production-ready connector with active maintenance, no known vulnerabilities, and broad Python version support (3.10–3.14 including free-threaded). Medium install friction from native dependencies is typical for database drivers. Apache-2.0 license poses no commercial barrier.
