v1.14.0

• Minimum Go version is now 1.25.0 (previously 1.20): the go directive was raised to 1.25.0 while clearing OSV-Scanner findings and updating dependencies. Consumers building with an older toolchain will need to upgrade Go (#368)
• Fix panic in InitThriftClient when the endpoint URL is malformed: the thrift transport was type-asserted to *thrift.THttpClient before the error from NewTHttpClientWithOptions was checked, so a URL that fails to parse (nil transport) caused interface conversion: thrift.TTransport is nil, not *thrift.THttpClient; the error is now returned instead (#394)
• Stop using html/template in the U2M OAuth callback page. Reachable use of html/template disabled the Go linker's dead-code elimination for the entire binary of any application importing this driver; the page is now rendered with plain string building and explicit HTML escaping, restoring full DCE (#343)
• Fix DECIMAL precision loss inside complex types: DECIMAL values nested in STRUCT, ARRAY, and MAP columns are now rendered losslessly with their exact scale (e.g. 19.99 instead of 19.990000000000002), matching the behavior of top-level DECIMAL columns (#253)

v1.13.1

• Expose native Arrow decimal handling: add the WithArrowNativeDecimal connector option and the useArrowNativeDecimal DSN parameter so DECIMAL columns can be returned as native Arrow decimal128 (via GetArrowBatches) instead of strings. When scanned through database/sql, native DECIMAL values are returned as lossless, scale-applied strings (#274)

v1.13.0

• Add SPOG (unified) host support: extract the org-id from the cluster HTTP path for non-Thrift requests, and fix U2M/M2M OAuth on unified AWS hosts (#367, #374)
• Cap CloudFetch Arrow batches to the server-declared row count to avoid over-reading (#372)
• Detach result streaming from QueryContext cancellation so in-flight results aren't dropped when the query context is cancelled (#373)

v1.12.0

• Retry transient S3 errors in CloudFetch downloads and staging PUT/GET/REMOVE operations (#355, #361)
• Telemetry: normalize host key for per-host client + breaker registries; stop retrying into 429s, honour Retry-After, fix userAgent (#354, #364)
• Bump dependencies to clear Go-1.20-compatible CVEs: golang-jwt, x/net, protobuf, go-jose v3.0.5 (CVE-2026-34986) (#360, #363)

v1.11.1

• Fix CloudFetch goroutine leak that retained Arrow buffers after Close (#357)

v1.11.0

• Enable telemetry by default with DSN-controlled priority (#320, #321, #322, #349)
• Add SPOG (Custom URL) routing support via x-databricks-org-id header (#347)
• Add statement-level query tag support (#341)
• Add AI coding agent detection to User-Agent header (#326)
• Fix CloudFetch returning stale column names from cached results (#351)
• Fix resource leak: close staging Rows in execStagingOperation (#325)

v1.10.0

• Add token federation / token provider support for OAuth (#290, #291, #292)
• Internal: add foundational telemetry infrastructure, disabled by default (#297, #304, #305, #311, #319)
• Fix type inference for int64/uint64 (BIGINT) and float64 (DOUBLE) (#316)
• Fix context loss in polling and connection close operations (#295)
• CloudFetch: allow configuration of HTTP client (#308)
• Add metric view metadata support (#286)
