2. Changelog⚓︎

2.1 Added⚓︎

• Added xApp Library instead of the xApp Python Template. Instead of having template Python files, we now have a full xApp Python Library, which abstracts the interfaces towards dRAX and dRAX RIC. More info can be found in the xApp Framework In-depth and xApp Library In-depth.
• Added new xApp Configuration API. More information can be found in the xApp Configuration In-depth section.

2.2 Changed⚓︎

• Updated the Workflows to add more options for easier development cycles. More info can be seen in the Quick guide, Development Workflows and Build your own xApp Dev Environment sections.
• As the new xApp Library is in place, all the previous abstractions of the interfaces are there, however, there are syntax changes. More info can be found in the xApp Library In-depth section.
• Updated the xApp API structure. More information can be found in the xApp Configuration In-depth section.
• The programmable approach to configuring the xApp has changed. More info can be found in the xApps Lifecycle In-depth section.
• The xApp Helm Chart has been updated to incorporate the changes above. More info can be found in the xApp Helm Chart In-Depth.

2.3 Removed⚓︎

• The xApp API has been removed as a separate Docker image. It is now integrated in the xApp Library and part of the xApp Core. More information can be found in the xApp REST API section.

2.4 Notes⚓︎

• In the Appendix: Conversion from the xApp Framework to the xApp Library section, we have summarized how to upgrade from the previous xApp Framework version 0.4.0 and 1.0.0 to the new 2.0.0.
