| The Eclipse Ditto teams is proud to announce the availability of Eclipse Ditto | ||
| [3.1.0](https://projects.eclipse.org/projects/iot.ditto/releases/3.1.0). | ||
|
|
||
| Version 3.1.0 brings **policy imports**, **AMQP 1.0 message annotation** support, **conditional message sending** and | ||
| other smaller improvements, e.g. regarding shutdown/restart improvements. | ||
|
|
||
|
|
||
| ## Adoption | ||
|
|
||
| Companies are willing to show their adoption of Eclipse Ditto publicly: | ||
| [https://iot.eclipse.org/adopters/?#iot.ditto](https://iot.eclipse.org/adopters/?#iot.ditto) | ||
|
|
||
| When you use Eclipse Ditto it would be great to support the project by putting your logo there. | ||
|
|
||
|
|
||
| ## Changelog | ||
|
|
||
| The main improvements and additions of Ditto 3.1.0 are: | ||
|
|
||
| * **Conditional message processing** based on a specified condition targeting the twin state | ||
| * Support for **reading/writing AMQP 1.0 "Message annotations"** in Ditto managed connections | ||
| * **Policy imports**: Reference other policies from policies, enabling reuse of policy entries | ||
| * Several Ditto explorer UI enhancements | ||
| * Support for configuring an **audience** for Ditto managed HTTP connections performing OAuth2.0 based authentication | ||
|
|
||
| The following non-functional enhancements are also included: | ||
|
|
||
| * End-2-End **graceful shutdown support**, enabling a smoother restart of Ditto services with less user impact | ||
| * Support for **encryption/decryption of secrets** (e.g. passwords) part of the Ditto managed connections before | ||
| persisting to the database | ||
| * IPv6 support for blocked subnet validation | ||
|
|
||

|
|
||

||
| ### New features | ||
|
|
||
| #### [Process/forward messages conditionally based on twin state](https://github.com/eclipse-ditto/ditto/issues/1363) | ||
|
|
||
| Similar to the [conditional requests](basic-conditional-requests.html) for CRUD of things, a (RQL based) `condition` | ||
| can now be passed when sending a messages from/to a thing. | ||
| There is a separate [blog post](2022-11-04-live-message-conditions.html) on this topic showing some example use cases. | ||
|
|
||
| #### [Support AMQP Message Annotations when extracting values for Headers](https://github.com/eclipse-ditto/ditto/issues/1390) | ||
|
|
||
| Ditto managed connections with the [AMQP 1.0](connectivity-protocol-bindings-amqp10.html) can now process | ||
| [AMQP 1.0 Message Annotations](http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-messaging-v1.0-os.html#type-message-annotations) | ||
| by reading/writing them as if they would be message headers. | ||
|
|
||
| #### [Let policies import other policies to enable re-use when securing things](https://github.com/eclipse-ditto/ditto/issues/298) | ||
|
|
||
| Coming back at a very old issue and feature request, it is now possible to reuse existing policies in other policies. | ||
| That enables many scenarios where it is important to provide certain access in a single policy and a change to that | ||
| policy is immediately applied to all policies importing that one. | ||
|
|
||
| For example, an administrator or support group could be defined in a global policy which gets referenced from all other | ||
| policies. When changes are required, e.g. a new user account is added as subject to the "administrator" policy, this | ||
| change must only be done for a single policy, being effective for potentially thousands of other policies. | ||
|
|
||
| #### Enhancements in Ditto explorer UI | ||
|
|
||
| We again received several contributions by [Thomas Fries](https://github.com/thfries), | ||
| who contributed the Ditto explorer UI. | ||
| The latest live version of the UI can be found here: | ||
| [https://eclipse-ditto.github.io/ditto/](https://eclipse-ditto.github.io/ditto/) | ||
|
|
||
| You can use it in order to e.g. connect to your Ditto installation to manage things, policies and even connections. | ||
|
|
||
| Contributions in this release: | ||
| * [Select Ditto Explorer UI "environment" via query parameter](https://github.com/eclipse-ditto/ditto/issues/1449) | ||
| * [Allow to use namespaces in search in Explorer UI](https://github.com/eclipse-ditto/ditto/pull/1519) | ||
| * [Explorer UI json payload for messages](https://github.com/eclipse-ditto/ditto/pull/1529) | ||
| * [Improved search filter in explorer ui](https://github.com/eclipse-ditto/ditto/pull/1531) | ||
| * [Explorer UI: fixed bug caused by filter dropdown](https://github.com/eclipse-ditto/ditto/pull/1534) | ||
|

|
||
| ### Changes | ||
|
|
||
| #### [End-2-end graceful shutdown support](https://github.com/eclipse-ditto/ditto/pull/1520) | ||
|
|
||
| The Ditto team again invested in improving graceful shutdown behavior of the single Ditto services, | ||
| e.g. to reduce the amount of failed (HTTP) requests in case of a rolling update. | ||
| Inflight requests are e.g. waited to complete before finally shutting down an instance which received a termination | ||
| request (e.g. from Kubernetes). | ||
|
|
||
| #### [Encrypt connection sensitive data stored in MongoDB](https://github.com/eclipse-ditto/ditto/pull/1550) | ||
|
|
||
| Add functionality to apply a symmetrical encryption/decryption of all known sensitive fields in a Ditto | ||
| managed connection stored in the DB. | ||
| See the updated [documentation](installation-operating.html#encrypt-sensitive-data-in-connections) for details. | ||
|
|
||
| #### [Adjust blocked subnet validation for IPv6](https://github.com/eclipse-ditto/ditto/pull/1522) | ||
|
|
||
| The Ditto team checked for compatibility of Ditto with IPv6 and found that the validation for blocked subnets did not | ||
| yet work with IPv6. | ||
| This is now supported. | ||
|
|
||
|
|
||
| ### Bugfixes | ||
|
|
||
| Several bugs in Ditto 3.0.x were fixed for 3.1.0. | ||
| This is a complete list of the | ||
| * [merged pull requests for milestone 3.1.0](https://github.com/eclipse-ditto/ditto/pulls?q=is:pr+milestone:3.1.0) | ||
|
|
||
| Here as well for the Ditto Java Client: [merged pull requests for milestone 3.1.0](https://github.com/eclipse-ditto/ditto-clients/pulls?q=is:pr+milestone:3.1.0) | ||
|
|
||
|
|
||
| ## Migration notes | ||
|
|
||
| There are no migration steps required when updating from Ditto 3.0.x to Ditto 3.1.0. | ||
| When updating from Ditto 2.x version to 3.1.0, the migration notes of | ||
| [Ditto 3.0.0](release_notes_300.html#migration-notes) apply. | ||
|
|
||
|
|
||
| ## Roadmap | ||
|
|
||
| Looking forward, the current plans for Ditto 3.2.0 are: | ||
|
|
||
| * [Addition of an Eclipse Hono connection type](https://github.com/eclipse-ditto/ditto/pull/1548) | ||
| * [Provide API to stream/replay persisted events from the event journal](https://github.com/eclipse-ditto/ditto/issues/1498) | ||
| * Perform a benchmark of Ditto and provide a "tuning" chapter in the documentation as a reference to the commonly | ||
| asked questions | ||
| * how many Things Ditto can manage | ||
| * how many updates/second can be done | ||
| * whether Ditto can scale horizontally | ||
| * how many resources (e.g. machines) are required at which scale |
