The major changes for this release are:

• Proxies fix
• Updated proto files used by PowerShell worker
• Set response Content-Type to 'application/json' when an object is provided to Body
• Managed Dependencies (MDs) enhancements:
  • Added retry logic for module installation with a maximum of 3 retries
  • If unable to reach the PSGallery during installation:
    • If this is the first time we are installing MDs, we error out and stop execution
    • If there is a previous installation of MDs, log that we could not connect to the PSGallery and continue with the function app execution
• Enhancements to throughput performance
