Version: 1.4.4
--------------

:Release Date: 2019-1-31


**Bug Fixes**

The Casablanca maintenance release fixed the following bugs:

	- `APPC-1247 <https://jira.onap.org/browse/APPC-1247>`_ - java.lang.NoClassDefFoundError when publishing DMAAP message

	- `CCSDK-741 <https://jira.onap.org/browse/CCSDK-741>`_ - Removed Work-around required for vCPE use case to correct the error described in CCSDK ticket.
 
Special Note for `APPC-1367 <https://jira.onap.org/browse/APPC-1367>`_ - APPC fails healthcheck with 404 error:

       During testing, we found there is a timing issue. When using OOM to deploy to k8s environment the clustered MariaDB database is not accessible at the time when the APPC pod is trying to insert the DG into MariaDb. This would cause the healthcheck issue. The workaround to solve this issue is redeploying the APPC pod.

**Known Issues**

	- `APPC-1247 <https://jira.onap.org/browse/APPC-1247>`_ - java.lang.NoClassDefFoundError when publishing DMAAP message
	    - This issue is relevant during the vCPE use case.
	    - Due to this defect, the VM will perform four start/stop sequences, instead of the normal one.
	    - After the four start/stop sequences, the VM will be left in the correct state that it should be in.
	
	- Work-around required for vCPE use case to correct the error described in: `CCSDK-741 <https://jira.onap.org/browse/CCSDK-741>`_
	    - CCSDK aai adapter doesn't recognize generic-vnf attribute in the response, as it is not defined by aai_schema XSD
	    - To work around this, several steps must be performed as described here:
	        
	        1. Add a restapi template file into the appc docker containers
	            a. Enter the appc docker container (docker exec... or kubectl exec...)
	            b. Create a directory: /opt/onap/appc/templates
	            c. Download this file `aai-named-query.json <https://gerrit.onap.org/r/gitweb?p=appc/deployment.git;a=blob_plain;f=vcpe-workaround-files/aai-named-query.json;hb=refs/heads/casablanca>`_ and place it in that directory
	        2. Replace the generic restart DG with a new one
	            a. Download the `APPC_Generic_Restart.xml <https://gerrit.onap.org/r/gitweb?p=appc/deployment.git;a=blob_plain;f=vcpe-workaround-files/APPC_method_Generic_Restart_3.0.0.xml;hb=refs/heads/casablanca>`_
	            b. Edit the file. Find the parameter definition lines for restapiUrl, restapiUser, restapiPassword (lines 52-54) and replace these with the correct values for your aai server.
	            c. Copy this file into the appc docker containers to the /opt/onap/appc/svclogic/graphs directory (you will be replacing the old version of the file with this copy)
	        3. Load the new DG file
	            a. In the appc docker containers, enter the "/opt/appc/svclogic/bin directory
	            b. Run install-converted-dgs.sh

		- Currently APPC only supports OpenStack.

		- Admin level access for Tenant level operations.

		- OpenStack Hypervisorcheck is turned off by default.


	- Integration with MultiCloud is supported for Standalone Restart (i.e., not via DGOrchestrator). For any other action, such as Stop, Start, etc.. via MultiCloud requires the MultiCloud identity URL to be either passed in the payload or defined in appc.properties.

**Other**

- Limitations, Constraints and other worthy notes

	- An issue was discovered with usage of AAF in an OOM deployed environment after the Beijing release was created. The issue was twofold (tracked under `APPC-977 <https://jira.onap.org/browse/APPC-977>`_):
	  
	     - Needed APPC configuration files were missing in Beijing OOM , and 
	     - AAF updated their certificates to require 2way certs, which requires APPC updates 
		 
          Additionally, in a Heat deployed environment, a manual workaround will be required to authorize with AAF if they are using 2way certificates.  For instruction on workaround steps needed depending on type of deployment, please refer to the following wiki: https://wiki.onap.org/display/DW/AAF+Integration+with+APPC.  

        - During the testing of the vCPE/vMUX closed loop scenarios in an OOM deployed environment, an issue was encountered where transactions were not being deleted from the TRANSACTION table and was blocking other Restart request from completing successfully (tracked under `APPC-987 <https://jira.onap.org/browse/APPC-987>`_). A workaround is available and documented in the Jira ticket.

        - It is impossible for us to test all aspect of the application. Scope of testing done in Beijing is captured on the following wiki:   https://wiki.onap.org/display/DW/APPC+Beijing+Testing+Scope+and+Status
	  
	- Currently APPC only supports OpenStack
	  
	- OpenStack Hypervisorcheck is turned off by default. If you want to invoke this functionality via the appc.properties, you need to enable it and ensure you have Admin level access to OpenStack.
	  
	- Integration with MultiCloud is supported for Standalone Restart (i.e., not via DGOrchestrator). For any other action, such as Stop, Start, etc.. via MultiCloud requires the MultiCloud identity URL to be either passed in the payload or defined in appc.properties.
	  
	- APPC needs Admin level access for Tenant level operations. 
	  
	- Currently, the "ModifyConfig" API and the implementation in the Master Directed Graph is only designed to work with the vFW Closed-Loop Demo.
  

Version: 1.2.0
--------------

:Release Date: 2017-11-16


**New Features**

The Amsterdam release continued evolving the design driven architecture of and functionality for APPC. 
APPC aims to be completely agnostic and make no assumption about the network. 

The main goal of the Amsterdam release was to:
 - Support the vCPE use case as part of the closed loop action to perform a Restart on the vGMUX
 - Demonstrate integration with MultiCloud as a proxy to OpenStack 
 - Continue supporting the vFW closed loop use case as part of regression from the seed contribution. 

Other key features added in this release include:
 - Support for Ansible 
   - The Ansible Extension for APP-C allows management of VNFs that support Ansible. Ansible is a an open-source VNF management framework that provides an almost cli like set of tools in a structured form. APPC supports Ansible through the following three additions: An Ansible server interface, Ansible Adapter, and Ansible Directed Graph. 
 - Support for Chef 
   - The Chef Extension for APPC allows management of VNFs that support Chef through the following two additions: a Chef Adapter and Chef Directed Graph.
 - LifeCycle Management (LCM) APIs via standalone DGs or via the DGOrchestrator architecture to trigger actions on VMs, VNFs, or VNFCs
 - OAM APIs to manage the APPC application itself
 - Upgrade of OpenDaylight to Carbon version


**Bug Fixes**

	- This is technically the first release of APPC, previous release was the seed code contribution. As such, the defects fixed in this release were raised during the course of the release. Anything not closed is captured below under Known Issues. If you want to review the defects fixed in the Amsterdam release, refer to `Jira <https://jira.onap.org/issues/?filter=10570&jql=project%20%3D%20APPC%20AND%20issuetype%20%3D%20Bug%20AND%20status%20%3D%20Closed%20AND%20fixVersion%20%3D%20%22Amsterdam%20Release%22>`_. 
	
	- Please also refer to the notes below. Given the timeframe and resource limitations, not all functions of the release could be validated. Items that were validated are documented on the wiki at the link provide below. If you find issues in the course of your work with APPC, please open a defect in the Application Controller project of Jira (jira.onpa.org)
	
**Known Issues**

	- `APPC-312 <https://jira.onap.org/browse/APPC-312>`_ - APPC request is going to wrong request handler and rejecting request. Configure request failing with following error: ``REJECTED Action Configure is not supported on VM level``.
	
	- `APPC-311 <https://jira.onap.org/browse/APPC-311>`_ - The APPC LCM Provider Healthcheck, which does a healthceck on a VNF, is failing. No known workaround at this time. 
	
	- `APPC-309 <https://jira.onap.org/browse/APPC-309>`_ - The property: ``appc.LCM.provider.url=http://127.0.0.1:8181/restconf/operations/appc-provider-lcm`` is missing from appc.properties in the appc deployment.  The property can be manually added as a workaround, then bounce the appc container. 
	
	- `APPC-307 <https://jira.onap.org/browse/APPC-307>`_ - Missing jackson-annotations dependency in appc-dg-common - This issue results in Rebuild operation via the APPC Provider not to work. Use instead Rebuild via the APPC LCM Provider using DGOrchestrator.
	
	- `APPC-276 <https://jira.onap.org/browse/APPC-276>`_ - A number of junit testcases need to be reworked because they are causing APPC builds to take much  longer to complete. This issue does not cause the build to fail, just take longer. You can comment out these junit in your local build if this is a problem. 
	  
	- `APPC-248 <https://jira.onap.org/browse/APPC-248>`_ - There is an compatibility issue between PowerMock and Jacoco which causes Sonar coverage not to be captured. There is no functional impact on APPC.
	 
	- `APPC-154 <https://jira.onap.org/browse/APPC-154>`_ - Logging issue - Request REST API of APPC has RequestID (MDC) in Body or Payload section instead of Header.
