The libdbi-drivers project hosts the database-specific drivers for
libdbi, a database abstraction library written in C. Currently,
drivers are available for Firebird/Interbase, FreeTDS (MS-SQL and
Sybase client), mSQL, MySQL, Oracle, PostgreSQL, and SQLite/SQLite3.


Changes:
Two bugs in the SQLite and SQLite3 drivers were fixed. An option to
improve concurrent access was added to these drivers. The
Firebird/Interbase and FreeTDS drivers are now fully functional.
