About
Binary JAR file downloads of the JDBC driver are available here and the current version with Maven Repository .

Source versions are also available here for recent driver versions.
Current Version 42.3.1
This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using. It supports PostgreSQL 8.2 or newer and requires Java 8 or newer. It contains support for SSL and the javax.sql package.
Other Versions
Many other versions of the JDBC driver are available. This includes development versions, compatibility with older JDKs, and previous versions of the driver.
