Jaybird 3.0.9

The following has been changed or fixed since Jaybird 3.0.8

• Fixed: changes to the transaction configuration (transaction parameter buffer configuration) of one connection are no longer propagated to other connections with the same connection properties (JDBC-386)
  This change introduce a binary incompatibility as method setTransactionParameters(int, TransactionParameterBuffer) in FBManagedConnection can now throw ResourceException where previously it did not. Under the assumption that most users of Jaybird are not directly using this class, the change should not break anything.
• New feature: Firebird 4 data type bind configuration support (JDBC-603)
  This change also removes the timeZoneBind and decfloatBind connection properties introduced in Jaybird 3.0.6 as the corresponding DPB items were removed from Firebird 4. This feature requires Firebird 4 beta 2 or snapshot Firebird 4.0.0.1683 or higher.
  See also Limited support for new Firebird 4 data types.
• New feature: Jaybird now supports UTF-8 URL encoding for connection properties in the JDBC url. (JDBC-604)
  This introduce a minor incompatibility, see also URL encoding in query part of JDBC URL.
• Fixed: When updating a row through an updatable result set, selected but not updated blob fields were set to NULL (JDBC-623)

Jaybird 3.0.7

The following has been changed or fixed since Jaybird 3.0.6

• Fixed: attempts to use a blob after it was freed or after transaction end could throw a NullPointerException or just work depending on whether the connection had a new transaction. (JDBC-587)
• Fixed: Instances of java.sql.Blob and java.sql.Clob obtained from a result set were freed after calls to ResultSet.next(). (JDBC-588)
• New feature: added FBEventManager.createFor(Connection) to create an EventManager for an existing connection. Backported from Jaybird 4. (JDBC-594)

Jaybird 3.0.6

The following has been changed or fixed since Jaybird 3.0.5

• Fixed: Exceptions during fetch of cached result sets (holdable over commit, scrollable and metadata) prevented prepared statement reuse/re-execute with error "Statement state CURSOR_OPEN only allows next states [CLOSING, PREPARED, ERROR], received EXECUTING" (JDBC-531)
• Improvement: Added FBManager.setDefaultCharacterSet to set default database character set during database creation (JDBC-541)
• New feature: Support for Firebird 3 case sensitive user names (JDBC-549)
• Fixed: Savepoints did not work in connection dialect 1 as savepoint names were always quoted (JDBC-556)
• Changed: The DatabaseMetaData statement cache introduced in Jaybird 3 was unlimited, it is now limited to 12 prepared statements; the least recently used statement will be closed and removed when a new statement is added (JDBC-557)
• Fixed: UPDATE OR INSERT with existing RETURNING clause handled incorrectly for generated keys (JDBC-566)
• Fixed: Exceptions during initialization of result sets would not properly close the database cursor leading to error "Current statement state (CURSOR_OPEN) does not allow call to prepare" on reuse of the statement (or errors similar to described for JDBC-531 above). (JDBC-571)
  A stopgap measure has been added to prevent similar problems from occurring. This will log its use on debug-level with message "ensureClosedCursor has to close a cursor at" and a stacktrace.
• New feature: boolean connection property ignoreProcedureType to disable usage of metadata for stored procedure types in CallableStatement. When set to true, call escapes and EXECUTE PROCEDURE will default to use EXECUTE PROCEDURE and not switch to SELECT for selectable stored procedures. (JDBC-576)
• New feature: connection properties timeZoneBind and sessionTimeZone for limited support for Firebird 4 TIME(STAMP) WITH TIME ZONE types, and decfloatBind for limited support for Firebird 4 DECFLOAT types. (JDBC-538)
• Fixed: Connection property defaultIsolation/isolation did not work through DriverManager, but only on DataSource implementations. (JDBC-584)
