Column names don't match metadata in cases where server doesn't return original column names (column functions) thus breaking compatibility with applications that expect 1-1 mappings between findColumn() and rsmd.getColumnName(), usually manifests itself as "Can't find column ('')" exceptions. (Bug#21379)

When using information_schema for metadata, COLUMN_SIZE for getColumns() is not clamped to range of java.lang.Integer as is the case when not using information_schema, thus leading to a truncation exception that isn't present when not using information_schema. (Bug#21544)

Newlines causing whitespace to span confuse procedure parser when getting parameter metadata for stored procedures. (Bug#22024)

Driver was using milliseconds for Statement.setQueryTimeout() when specification says argument is to be in seconds. (Bug#22359)

Workaround for server crash when calling stored procedures via a server-side prepared statement (driver now detects prepare(stored procedure) and substitutes client-side prepared statement). (Bug#22297)

Added new _ci collations to CharsetMapping - utf8_unicode_ci not working. (Bug#22456)

Driver issues truncation on write exception when it shouldn't (due to sending big decimal incorrectly to server with server-side prepared statement). (Bug#22290)

DBMD.getColumns() does not return expected COLUMN_SIZE for the SET type, now returns length of largest possible set disregarding whitespace or the "," delimitters to be consistent with the ODBC driver. (Bug#22613)

Fixed configuration property jdbcCompliantTruncation was not being used for reads of result set values.

Driver now supports {call sp} (without "()" if procedure has no arguments).

Driver now sends numeric 1 or 0 for client-prepared statement setBoolean() calls instead of '1' or '0'.

DatabaseMetaData correctly reports true for supportsCatalog*() methods.
