+Title: Apache Sling Launchpad 9 released
+
+Here are some of the more noteworthy things available in this release.
+
+Updated to Oak 1.6.1 and segment-tar persistence
+---
+
+We now include the latest stable version of Oak and have switched to the latest
+form of the disk-based persitence - oak-segment-tar. This module provides better
+runtime characteristics when compared to the oak-segment persistence and also
+allows reliable online compaction of the repository.
+
+If you're upgrading from a previous version of Sling you will need to manually
+upgrade the repository. See the [Oak documentation on Repository migration](http://jackrabbit.apache.org/oak/docs/migration.html)
+for more details.
+
+The Sling Explorer is replaced with Composum
+---
+
+The Sling Launchpad ships with a new repository explorer and administration tool - [Composum](https://github.com/ist-dresden/composum). Composum is more reliable and featurefull compared to the
+previous Sling explorer.
+
+New Resource Provider and Observation API
+---
+
+The Resource Provider API has been replaced with a new implementation, which is more performant
+and better suited for future evolution. Existing ResourceProvider will be able to work using
+a backwards-compatible layer, but developers are nonetheless encouraged to move to the
+new implementation.
+
+In the same manner, the Observation API has been refreshed.
+
+
+New modules added: Validation, Context-Aware Configuration, Repository Initialization Language
+---
+
+A number of new general-purpose modules have been added to the Sling Launchpad:
+
+* [Validation]({{refs.documentation.bundles.validation.path}})
+* [Context-Aware configuration]({{refs.bundles.context-aware-configuration.context-aware-configuration.path}})
+* [Repository Initialization Language]({{refs.bundles.repository-initialization.path}})
+
+Tooling: HTL Maven Plugin
+---
+
+The [HTL Maven Plugin](http://sling.apache.org/components/htl-maven-plugin/) provides build-time validation for projects using Sightly.
+
+Streaming Upload Support
+---
+
+The version of the Sling Engine shipped in the Launchpad now supports streaming uploads,
+for better I/O throughput. Streaming uploads are opt-in via setting the following HTTP Header:
+
+    Sling-UploadMode: stream
+
+Discovery: added Oak-based discovery implementation
+---
+
+The Sling discovery mechanism has been augmented with a mechanism which delegates instance
+discovery to Oak. When working with a DocumentNodeStore-based Oak implementation, this information
+is already available to Oak so there is no point in duplicating the work.
+
+Security: loginAdministrative deprecation
+---
+
+We believe that the vast majority of bundles performing background work do not require
+administrative access to the repository via `loginAdministrative`. We have removed many usages
+of `loginAdministrative` in the Sling code and replaced then with a service-based approach
+- `loginService`. We encourage you to do the same.
+
+Documentation available at [Service Authentication]({{refs.the-sling-engine.service-authentication.path}}).
+
+Removed org.apache.sling.commons.json and org.json bundles
+---
+
+Apache projects are no longer allowed, for legal reasons, to ship code which uses or links to the 
+JSON.org Java implementation. As a consequence we have removed all code which references that
+API.
+
+If you need to use these bundles, you can always retrieve then from Maven Central and incorporate
+them in your launchpad.
