-- Update WebJobsScriptHostService to remove hardcoded sleep during application shut down (#9520)
+- Increased maximum HTTP request content size to 210000000 Bytes (~200MB)
+- Update Node.js Worker Version to [3.8.1](https://github.com/Azure/azure-functions-nodejs-worker/releases/tag/v3.8.1)

-- Add support for standalone executable (ie: `dotnet build --standalone`) for out-of-proc workers in Linux Consumption. (#9550)
-- Bug fix: Do not restart worker channels or JobHost when an API request is made to get or update the function metadata (unless the config was changed) (#9510)
-  - This fixes a bug where requests to 'admin/functions' lead to a "Did not find initialized workers" error when
-    worker indexing is enabled.
-- Bug fix: If there are no channels created and the host is running, restart the JobHost instead of shutting down worker channels (#9510)
-  - This fixes a bug with worker indexing where we are shutting down worker channels and creating a new channel that never
-    gets properly initialized as the invocation buffers are not created - this leads to a "Did not find initialized workers" error.
-- Check if a blob container or table exists before trying to create it (#9555)
 - Limit dotnet-isolated specialization to 64 bit host process (#9548)
 - Sending command line arguments to language workers with `functions-` prefix to prevent conflicts (#9514)
