- Improved SQLTables, SQLColumns, and SQLTablePrivileges performance by running their SHOW commands over the unnamed prepared-statement protocol, removing a redundant per-call server-side prepare.
- Fixed IAM authentication to pass the default CA file path to libcurl as UTF-8, resolving connection failures on Linux and macOS when CaFile is not set.
- Fixed ODBC escape-clause parsing to accept date/time/timestamp literals with no space after the keyword (for example {ts'2026-07-08 07:45:00'}) and fixed a use-after-free on malformed clauses.
- Fixed JWT/OAuth authentication to honor connection-level StsConnectionTimeout and StsEndpointUrl on the STS call.
- Further improved metadata query performance by skipping redundant match-all (%) filters.
