+Istanbul release updates
+------------------------
+Below aspects are covered in Istanbul release:
+
+1. **CPS-TBDMT Enhancements** - This service shall be used to map the erstwhile Config-DB-like REST APIs to appropriate CPS API calls. The purpose of this service is to abstract the details of (possibly multiple, and complex) XPath queries from the users of CPS. It enables CPS-users to continue using simple REST API calls that are intuitive and easy-to-understand and implement. The mapping to appropriate queries to CPS (including mapping of one API call to many Xpath queries) shall be done in a generic way by the CPS-TBDMT service. In Istanbul release, following are the main enhancements done:
+
+ - Support edit query ie. post, put and patch requests to CPS
+
+ - Support Output Transformation
+
+ (a) Extract desired output from the data returned from CPS.
+ (b) If 'transformParam' is not defined in the template no transformation takes place.
+ - Support Multiple query
+
+ (a) Make multiple queries to CPS in single request.
+ (b) If 'multipleQueryTemplateId' is mentioned in the template, it will execute this template first and insert the result to the current template to make multiple queries to CPS.
+ - Support Delete data requests to CPS
+
+ (a) Process delete request type.
+ - Support for dynamic anchor - Accept anchors at run time and execute query
+
+2. **CPS Integration**
+
+ - Config DB is replaced with the CPS component to read, write, update and delete the RAN Slice details. CPS APIs are accessed via CPS-TBDMT component. CPS integration with DCAE - Slice Analysis MS and OOF are completed. SDN-R integration with CPS is completed for the shared RAN Slice flow, activateRANslice and terminateRANSlice implementations are in progress.
+ - A new SDN-C karaf feature is introduced to register the cm-handle (anchor) with CPS. The integration with CPS-DMI plugin will be done in Jakarta release.
+
+3. **NSMF based TN Slices** - Support for interacting with TN NSSMF directly from NSMF for front haul and mid haul slice subnets. There will be separate SDC template for this scenario. NST will have 5 NSSTs - CN NSST, AN NSST, TN FH NSST, TN MH NSST, TN BH NSST.
+
+4. **KPI Monitoring** - Implementation is done in KPI Computation MS to configure the required KPIs and the KPI computaion formula based on policies.
+
+5. **Closed Loop** - Closed Loop updates are sent over A1 interface to NearRT-RIC. This is done at the POC level. This will be further enhanced in Jakarta release to make use of the A1-Policy Management Service in CCSDK.
+
+6. **Intelligent Slicing** - End to end intelligent slicing - closed loop flow is tested with the initial version of Machine Learning MS.
+
+7. **Carry-over Testing from Honolulu Release**
+
+ - RAN NSSMF Testing
+
+ (a) Testing completed for the allocation, modification, activation and deactivation of the RAN slice to support option1
+ (b) Integration Testing of AN NSSMF with SDNR interactions for allocate and modify flow is completed
+ - E2E Testing
+
+ (a) Service instantiation for non-shared and shared scenario and fixes to support option 1 are done
+ (b) NSI selection process support for shared NSI is tested
+
+Impacted Modules for Istanbul Release
+-------------------------------------
+- **SO**:
+
+ (a) Support of NSI termination by enhancing the interaction with OOF, AAI and UUI
+ (b) RAN NSSI Termination support with OOF & SDN-R interactions
+ (c) Bug fixes in Option 1 (CSMF, NSMF and NSSMFs are within ONAP & TN-FH, TN-MH are created by RAN NSSMF)
+
+ - **CSMF**: Fixed sNSSAI format and updated authentication for NSMF invocation
+ - **NSMF**: Fixes in NSI termination issues to support OOF interaction for NSI termination query and added subnet Type support for respective TN Domain
+ - **AN NSSMF**: Fixes for different termination scenarios in Option 1
+ - **CN NSSMF**: Bug fixes in shared allocate flow, modify flow and terminate flow
+ - Slice Profile alignement with NSSMF
+ (d) NSMF based TN Slices (TN-FH, TN-MH are created by NSMF) - Work flow changes to support this approach
+
+- **OOF**
+ (a) Integration with CPS for coverage area to coverage area TA list
+ (b) Bug fixes in NxI termination
+
+- **DCAE**
+ (a) Minor changes in Slice Analysis MS to support CPS integration
+ (b) KPI Computation MS in enhanced to support policy based KPIs and formula
+
+- **SDN-R**
+ (a) Bug fixes in instantiateRANSliceAllocate, instantiateRANSliceAllocateModify, activateRANSlice, terminateRANSlice Directed Graphs
+ (b) CPS integration for the instantiateRANSliceAllocateModify, activateRANSlice, terminateRANSlice Directed Graphs
+ (c) A new karaf feature is introduced to register the cm-handle with CPS
+
+- **CPS-TBDMT** - This component is enhanced to support different type of queries based on templates
+
+- **CPS** - Bug fixes and support for GET, POST, PATCH and DELETE type of queries.
+
