Official Release — November 9, 2026
Open DBX4 ODBC Driver Remastered (dbx4odbc) is officially released!
Based on the original open-source project Open source dbExpress drivers, this project has been reengineered as a native DBX4 ODBC driver.
Supporting Delphi 10 through Delphi 13 Florence, it provides a free, open-source ODBC driver alternative for Delphi Professional and Community Edition users, as well as developers maintaining legacy dbExpress applications built with Enterprise or Architect editions.
What's New in Version 4.2026.11.09.1
- Native DBX4 Architecture: Reengineered the ODBC driver using the native DBX4 specification, eliminating the legacy DBX3 compatibility layer. Implemented entirely in Pascal with Win32 and Win64 support.
- Modern ODBC Compatibility: Primarily validated against Microsoft SQL Server, supporting modern Microsoft ODBC drivers with improved compatibility for DataSnap, BLOB handling, metadata, and the Delphi Data Explorer.
- Documentation and Performance Benchmarks: Includes comprehensive documentation, architecture decision records, and performance benchmarks comparing FireDAC, ADO, Embarcadero Native DBX SQL Native Client, and Embarcadero Native DBX ODBC.
