Netty upgraded from 3.5.9.Final to 4.1.133.Final

The embedded Netty dependency has been upgraded from io.netty:netty:3.5.9.Final to io.netty:netty-all:4.1.133.Final. This brings security fixes and removes end-of-life Netty 3 from the transitive dependency tree.

Breaking change: The ReceivedBytesListener.onReceivedBytes method signature has changed:

// Before (Netty 3)
void onReceivedBytes(TemplateId templateId, org.jboss.netty.buffer.ChannelBuffer bytes);

// After (Netty 4)
void onReceivedBytes(TemplateId templateId, io.netty.buffer.ByteBuf bytes);

Update your import statements and replace ChannelBuffer with ByteBuf in any ReceivedBytesListener implementations. The io.netty:netty-all artifact must be on the classpath if you reference ByteBuf directly; it is already pulled in transitively by the handler.

New method ConnectionSettings.addAddressMapping

A new method addAddressMapping is added to ConnectionSettings to allow redirecting connections from one host/port endpoint to another.

Default TLS protocol changed to TLSv1.3

The default TLS protocol has been changed from TLSv1.2 to TLSv1.3. Eurex has decommissioned TLSv1.2 support. To override, use ConnectionSettings.setEnabledSslProtocols.

New HandlerSettings properties for sender and receiver thread affinity

To improve performance on NUMA and multi-socket systems, HandlerSettings now exposes setSendingThreadAffinity(int[]) and setReceivingThreadAffinity(int[]) methods that pin the respective I/O threads to specific CPU cores.

Add Password Encryption

Remove HandlerSettings's properties

The following properties are removed from the HandlerSettings class:

• gatewayPassword;
• partyIdSessionId.

Set these values directly in the LogonRequest.
