Jaybird 4.0.4 has been released.

The following has been changed since Jaybird 4.0.3:

• Fixed: ResultSet.updateRow() sets fields to null in result set only (jaybird#37)
• New feature: Support for NBackup GUID-based backup and in-place restore (jaybird#672)
• Fixed: Logic error could lead to incorrect logging of "Specified statement was not created by this connection" (jaybird#674)
• Changed: Updated Firebird 4.0 reserved words based on 4.0.0.2496 (jaybird#597)
• Fixed: Protocol 15 and 16 had same priority, so Firebird 4.0 might select protocol 15, leading to timeout support not available. (jaybird#676)

Jaybird 4.0.4
Jaybird 4 supports Firebird 2.5 and higher, on Java 7, 8, 11, and 17 (support for Java 17 using the Java 11 version of the driver). See also:

The firebird-driver package provides official Python Database API 2.0-compliant driver. In addition to the minimal feature set of the standard Python DB API, this driver also exposes the new (interface-based) client API introduced in Firebird 3, and number of additional extensions and enhancements for convenient use of Firebird RDBMS. The driver is written as pure-Python package (requires Python 3.8+) on top of Firebird client library (fbclient.so/dll) using ctypes. Driver supports Firebird version 3.0 and higher.

You can download this driver from PyPI or or install it using pip.

This release contains bug fixes and expanded support for Firebird 4 features. See the Changelog for full details.
