We are extremely pleased to announce that Eclipse Vert.x version 4.1.1 has been released.

Since the release of Vert.x 4.1.0, quite a few bugs have been reported. We would like to thank you all for reporting these issues.

This release also provides a few small features that were postponed from previous release.

Sql Client pool enhancements

The pool supports now load balancing accross multiple servers:

PgPool pool = PgPool.create(vertx, Arrays.asList(server1, server2);

There is a new hook for customizing connection after it has been created and before it is inserted in the pool:

pool.connectHandler(conn -> {
  conn.query(sql).execute().onSuccess(res -> {
    // Release the connection to the pool, ready to be used by the application
    conn.close();
  });
});

Finally

A few other noticeable improvements are available

• Jackson 2.11.4 upgrade
• MSSQL now supports batch queries as well as packet size configuration
• The PostgreSQL client now supports the INET data type
• MSSQL metadata version is now retrieved
• Redis Client exposes now pool metrics through the Vert.x metrics reporting
• HTTP server invalid request handler hook to customize invalid request responses
• Redis client fix for well known Azure issue
• Mail client supports NTLM

The 4.1.1 release notes can be found on the wiki.
