What’s new

The major changes and new features in Jaybird 6 are:

• Minimum supported Java version is Java 17.
  See Java support for more information.
• Minimum supported Firebird version is Firebird 3.0.
  See Firebird support for more information.

  See Pure Java will not connect to unsupported Firebird versions by default for more information.
• The native and embedded protocols have been moved to a separate artifact, jaybird-native.
  See NATIVE and EMBEDDED support moved to a separate artifact for more information.
• OOREMOTE (OpenOffice/LibreOffice protocol) removed
• Modularization of Jaybird
• Connection property createDatabaseIfNotExist
• Report actual process ID (pid)
• Logging facade removed
• Support for ChaCha64 wire encryption
• Opt-in feature for package information in DatabaseMetaData
• Asynchronous fetching
• Blob performance improvements
• Support for executing transaction management statements

Upgrading from Jaybird 5 should be straightforward, but please make sure to read Compatibility changes before using Jaybird 6. If you’re using Jaybird with the native or embedded connections, you will need to make some additional changes. See also Upgrading from Jaybird 5 to Jaybird 6.

Bug reports about undocumented changes in behavior are appreciated. Feedback can be sent to the Firebird-java mailing list or reported on the issue tracker https://github.com/FirebirdSQL/jaybird/issues.

Maven

The release is also available on Maven:

groupId: org.firebirdsql.jdbc
artifactId: jaybird
version: 6.0.0-beta-1

If you use the native or embedded protocol, you need to add the jaybird-native dependency:

groupId: org.firebirdsql.jdbc
artifactId: jaybird-native
version: 6.0.0-beta-1

For ChaCha64 wire encryption support, add the chacha64-plugin dependency:

groupId: org.firebirdsql.jdbc
artifactId: chacha64-plugin
version: 6.0.0-beta-1

We are happy to announce the release of Jaybird 5.0.6.

The following has been fixed since Jaybird 5.0.5:

• Fixed: Exceptions during statement execution did not always complete the statement, which could delay transaction commit in auto-commit mode (#806)
• Fixed: Closing a connection when the database was shutdown, or the connection was otherwise broken, could result in a NullPointerException (#812)
• Fixed: Error “Column unknown; IND.RDB$CONDITION_SOURCE” when calling DatabaseMetaData.getIndexInfo on Firebird 5.0 with a Firebird 4.0 (ODS 13.0) database (#813)
• Fixed: Calling ResultSet.wasNull() when on the insert-row throws a SQLException instead of reporting the null-state of the last retrieved column (#816)
• Fixed: Inserting a row into a result set backed by a server-side scrollable cursor could include the inserted row twice (#819)
• Improvement: Updated JNA dependency to version 5.15.0 (#823)

Jaybird 5 supports Firebird 2.5 and higher, on Java 8, 11, 17, 21, and 23 (support for Java 11 and higher using the Java 11 version of the driver).

We are happy to announce the release of Jaybird 5.0.5.

The following has been fixed since Jaybird 5.0.4:

• Optimized the query to retrieve extended field info for ResultSetMetaData.getPrecision to only retrieve columns of type NUMERIC or DECIMAL (#732)
• Fixed: PreparedStatement.executeBatch() of statement without parameters throws “Statement used in batch must have parameters [SQLState:07001, ISC error code:335545186]” on Firebird 4.0 or higher (#788)
• New feature: ResultSetMetaData.isAutoIncrement(int) reports true for identity columns if Jaybird can identify the underlying table and column (#793)

• Improvement: The FILTER_CONDITION of DatabaseMetaData.getIndexInfo is populated for Firebird 5.0 partial indices (#797)
• Fixed: ResultSet.isBeforeFirst() and ResultSet.isAfterLast() should always report false for an empty result set (#807)

• Java Connector Architecture (JCA) support removed
• ChaCha wire protocol encryption support (Java 11 and higher only)
• Changes to properties
• Unification of database and service addressing
• Changes to JDBC URL syntax
• Removal of LOCAL protocol implementation

• Firebird Embedded locator service provider (experimental)
• Table statistics of a connection (experimental)

Upgrading from Jaybird 4 to 5 should be simple, but please make sure to read Compatibility changes before using Jaybird 5. See also Upgrading from Jaybird 4 to Jaybird 5.
