 ## Versions and versioning

 An example of Current vs Dependency versions: `com.azure:azure-storage-blob-batch` has dependencies on `com.azure:azure-core`, `com.azure:azure-core-http-netty` and `com.azure:azure-storage-blob`. Because `com.azure:azure-core` and `com.azure:azure-core-http-netty` are both built outside of azure-storage pipeline we should be using the released or *Dependency* versions of these when they're dependencies of another library. Similarly, libraries built as part of the same pipeline, that have interdependencies, should be using the Current version. Since `com.azure:azure-storage-blob-batch` and `com.azure:azure-storage-blob` are both built part of the azure-batch pipeline when `com.azure:azure-storage-blob` is declared as a dependency of `com.azure:azure-storage-blob-batch` it should be the *Current* version.
 
-An example of an Unreleased Dependency version: Additive, not breaking, API changes have been made to `com.azure:azure-core`. `com.azure:azure-storage-blob` has a dependency on `com.azure:azure-core` and requires the additive API change that has not yet been released. An unreleased entry needs to be created in [version_client.txt](https://github.com/Azure/azure-sdk-for-java/blob/master/eng/versioning/version_client.txt), under the unreleased section, with the following format: `unreleased_<groupId>:<artifactId>;dependency-version`, in this example that would be `unreleased_com.azure:azure-core;1.2.0` (this should match the 'current' version of core). The dependency update tags in the pom files that required this dependency would now reference `{x-version-update;unreleased_com.azure:azure-core;dependency}`. Once the updated library has been released the unreleased dependency version should be removed and the POM file update tags should be referencing the released version.

 1. I'd open up eng\versioning\version_client.txt and update the current-versions of the libraries that are built and released as part of the azure storage pipeline. This list can be found in pom.service.xml under the sdk/storage directory. It's worth noting that any module entry starting with "../" are external module dependencies and not something that's released as part of the pipeline. Dependencies for library components outside of a given area would be downloading the appropriate dependency from Maven like we do for external dependencies.

 ### Management: New Releases
 A new set of management libraries that follow the [Azure SDK Design Guidelines for Java](https://azure.github.io/azure-sdk/java/guidelines/) are now Generally Available (GA) and ready for production uses. These new libraries provide a higher-level, object-oriented API for _managing_ Azure resources, that is optimized for ease of use, succinctness and consistency. You can find the list of new packages **[on this page](https://azure.github.io/azure-sdk/releases/latest/mgmt/java.html)**.

This tag will be used for servicing via hotfix branches as well as debugging the code for a particular preview or stable release version.
