+#### New features and enhancements in Zowe Application Framework
+#### Zlux App Manager
+* Updated the Desktop Angular version from 12 to 18.  Angular apps written for V2 will need to be upgraded to work in V3. `Iframe` and `React` is unaffected. ([#639](https://github.com/zowe/zlux-app-manager/pull/639))
+* The V2 Desktop is included alongside the V3 Desktop as a temporary compatibility option for the duration of the V2 maintenance schedule. Any user can switch to the V2 Desktop via the `?use-v2-desktop=true` parameter. ([#639](https://github.com/zowe/zlux-app-manager/pull/639))
+
+#### Zlux App Server
+* Added new `pluginDefinition` property to allow plugins to simultaneously contain v2 and v3 web assets. This property, `webContent.entryPoint`, can contain a “3.0” element which states the location of the entry JS file that the Desktop would load. See the `tn3270-ng2` app for an example of its usage. ([#323](https://github.com/zowe/zlux-app-server/pull/323)) ([#567](https://github.com/zowe/zlux-server-framework/pull/567))
+
+#### Zowe Common C
+* Added javascript `zos.getStatvfs`(path) function to obtain file system information. ([#482](https://github.com/zowe/zowe-common-c/pull/482))
+* Added support for `LE 64-bit` in isgenq.c. ([#422](https://github.com/zowe/zowe-common-c/issues/422))
+* Added more arguments to `httpClientSessionInit` to allow passing back rc. ([#467](https://github.com/zowe/zowe-common-c/issues/467)) 
+
+#### ZSS
+* If no `zowe.logDirectory` is defined in config, logging is disabled. ([#726](https://github.com/zowe/ZSS/pull/726))
+* Exposed new cross-memory server's functions in dynlink. ([#684](https://github.com/zowe/zss/issues/684)) 
+
+#### Bug fixes in Zowe Application Framework
+#### Zowe Common C
+* `IARV64` results must be checked for `0x7FFFF000` ([#474](https://github.com/zowe/zowe-common-c/pull/474))
+* `SLH` should not `ABEND` when `MEMLIMIT` is reached (additional NULL check)
+#### ZSS
+* Added Support for cross-memory server parameters longer than 128 characters. ([#684](https://github.com/zowe/zss/issues/684)) 
+
+### Known Issues
+Some apps and features of V2 Desktop have not yet been added to the V3 Desktop
+* The Editor app is not present on the V3 Desktop, but you can access it in the V2 desktop by including `?use-v2-desktop=true` at the end of your Desktop URL.
+* Support for languages other than English is limited. You can set your language preference in the V2 desktop, but this menu is not yet present in the V3 desktop and some parts of the V3 desktop will not yet honor the language choice.
