+##The LabKey Remote API Library for Java
+
+Welcome to the LabKey Remote API library for Java. This library allows Java developers to access the data and services exposed from a LabKey Server installation.
+
+For detailed information on the library, its classes, and programming interfaces, see the [JavaDoc](https://www.labkey.org/download/clientapi_docs/java-api/).
+
+If you have any questions about this library or the LabKey Server, see our [Community Support Forums](https://www.labkey.org/wiki/home/page.view?name=support).
+
+This library is licensed under the [Apache 2.0 open-source license](http://www.apache.org/licenses/LICENSE-2.0).
+
+---
+
+###Changes in version 1.0.0
+- Migration to [SemVer](https://semver.org/) for library versioning. With 1.0.0 we will move away from using the LabKey server version 
+and adopt the standard used in our other API libraries. Version 1.0.0 will succeed the previous published version of : 19.1.0.
+- Support for truncating tables, there is a new TruncateTableCommand to expose this functionality.
+- CRUD operations for Domains. 
+- Improved support for Assay data import. LoadAssayBatchCommand and SaveAssayRunCommand have been added to allow support for ad-hoc properties.
+- New ListDomainsCommand.
+- New SaveAssayRunsCommand.
+- Update PropertyDescriptor to expose missing value toggling.
