Changelog

5.9.0 (March 21, 2026)

This release includes a number of new features such as SCRAM-SHA-256-PLUS support, OAuth authentication support, and PostgreSQL protocol 3.2 support.

It significantly reduces the amount of network traffic when using prepared statements (which are used automatically by default) by avoiding unnecessary Describe Portal messages. This also reduces local memory usage.

It also includes multiple fixes for potential DoS due to panic or OOM if connected to a malicious server that sends deliberately malformed messages.

• Fix: reversed strings.ContainsAny arguments in Numeric.ScanScientific
• Fix: message length parsing on 32-bit platforms
• Fix: FunctionCallResponse.Decode mishandling of signed result size
• Fix: returning wrong error in configTLS when DecryptPEMBlock fails (Maxim Motyshen)
• Fix: misleading ParseConfig error when default_query_exec_mode is invalid (Skarm)
• Fix: missed Unwatch in Pipeline error paths
• Clarify too many failed acquire attempts error message
• Better error wrapping with context and SQL statement (Aneesh Makala)
• Enable govet and ineffassign linters (Federico Guerinoni)

• Fix various godoc comments (ferhat elmas)
• Fix typos in comments (Oleksandr Redko)

5.8.0 (December 26, 2025)

• Require Go 1.24+
