PostgreSQL JDBC Driver 42.0.0 Released

Notable Changes

Added

Replication protocol API was added: replication API documentation. PR 550
java.util.logging is now used for logging: logging documentation. PR 722
Add support for PreparedStatement.setCharacterStream(int, Reader). ee4c4265

Changed

Version bumped to 42.0.0 to avoid version clash with PostgreSQL version and follow a better semantic versioning. 46634923
Ensure executeBatch() can be used with pgbouncer. Previously pgjdbc could use server-prepared statements for batch execution even with prepareThreshold=0. Issue 742
Error position is displayed when SQL has unterminated literals, comments, etc. Issue 688
Strict handling of accepted values in getBoolean and setObject(BOOLEAN), now it follows PostgreSQL accepted values, only 1 and 0 for numeric types are acepted (previusly !=0 was true). PR 732
Return correct versions and name of the driver. PR 668

Removed

Support for PostgreSQL versions below 8.2 was dropped. PR 661

Deprecated

Deprecated PGPoolingDataSource, instead of this class you should use a fully featured connection pool like HikariCP, vibur-dbcp, commons-dbcp, c3p0, etc. PR 739

Regressions

Data truncated in setCharacterStream. Fixed in 42.1.0
No suitable driver found for jdbc:postgresql when using a DataSource implementation. Fixed in 42.1.0

You may have noticed the change in the versioning of the driver, you can read the FAQ for more information.
