It is a great milestone for this fast-growing project and the whole Pulsar community. This is the result of a huge effort from the community, with over 450 commits and a long list of new features, improvements, and bug fixes. + +Here is a selection of some of the most interesting and major features added to Pulsar 2.6.0. + +<!--truncate--> + +## Core Pulsar + +### [PIP-37] Large message size support + +This PIP adds support for producing and consuming large size messages by splitting the large message into multiple chunks. This is a very powerful feature for sending and consuming very large messages. + +Currently, this feature only works for the non-shared subscription and it has client-side changes. You need to upgrade the Pulsar client version to 2.6.0. You can enable the message trunk at the producer side as below. + +```java +client.newProducer() + .topic("my-topic") + .enableChunking(true) + .create(); +``` + +For more information about PIP-37, see [here](https://github.com/apache/pulsar/wiki/PIP-37:-Large-message-size-handling-in-Pulsar). <br> For more information about implementation details, see [PR-4440](https://github.com/apache/pulsar/pull/4400). + +### [PIP-39] Namespace change events (system topic) + +This PIP introduces the system topic to store namespace change events. Previously, Pulsar only allowed you to set the namespace policy, all topics under the namespace followed the namespace policy. Many users want to set the policy for topics. The main reason for not using the same way as namespace level policy is avoiding introducing more workload on ZooKeeper. + +The original intention of the system topic is able to store topic policy in a topic rather than ZooKeeper. So this is the first step to achieve topic level policy. And we can easily add support for the topic level policy with this feature.
