Full Changelog: 7.5.0...7.6.0

7.5.0

Release Date: July 7, 2026 | Download

New Features

• Implement string operations. This feature requires server version 8.1.3+. [CLIENT-4824]
• Support enhanced errors. This feature requires server version 8.1.3+. [CLIENT-4838]
• Create index to use “integer” instead of “numeric” for server version 8.1.3+. [CLIENT-4389]
• New release CI/CD pipeline. [CLIENT-4300]
• Support Ubuntu 26.04. [CLIENT-4799]

Bug Fixes

• Fix handling of libev as_ev_parse_authentication(). When user authentication is complete, as_ev_parse_authentication() watches for a write event and returns AS_EVENT_READ_COMPLETE. However, the calling code then incorrectly watches for a read event. Since, the event watching has already been performed in as_ev_parse_authentication(), the fix is to return instead of watching for a read. The same fix is also applied to libevent as_event_parse_authentication() handling. [CLIENT-4820]
• Change SendKey policy resolution from precedence hierarchy to union of sendKey settings. [CLIENT-4977]
• Add safeguarding against abort after a failed commit. [CLIENT-4960]

New Features

• Support recovering a connection after a client timeout. [CLIENT-3413]

• Remove unused EXP_DEPS variable in Makefile. [CLIENT-3640]
• Replace deprecated info commands with modern equivalents. [CLIENT-3628]
• Deprecate as_exp_device_size() and as_exp_memory_size(). Use as_exp_record_size() instead. [CLIENT-3628]

Bug Fixes

• Make batch result codes consistent between a batch with one key per node and a batch will multiple keys per node. [CLIENT-3403]
