Full Changelog: 1.2.6...4.0.0

Release 1.2.6

• Setting special limits for Python 3.6 and 3.7 (#890)
• Add a default script_file for function.json without scriptFile (#893)
• Update the max TP threads count to sys.maxsize (#875)

Release 1.2.5

• Fix an issue where the azure namespace is not initialized in placeholder mode
• Disable dependency isolation to fix an issue where azure. namespace related libraries are not able to load in Linux Consumption

Release 1.2.3

• Re-enable PYTHON_ISOLATE_WORKER_DEPENDENCIES.
• Fix an azure.functions module issue in its _thirdparty folder and fix azure namespace discovery.

Release 1.2.2

• Fix an issue where Python 3.9 Linux Consumption apps are facing 404 and 503 when the customer's files are not mounted during specialization.
• Re-enable worker status response to optimize the throughput

Release 1.2.1

• [HotFix] Disable WorkerStatus reporting due to the gRPC channel fails to acquire WorkerStatusResponse message from Python Queue structure, causing the Function Host /admin/host/ping endpoint to return 408 (timeout).

Release 1.2.0

• Added a new mechanism to transfer data between Functions Host and Python Worker via shared memory. This feature will improve the data transfer efficiency and performance especially when moving byte arrays between Host and Worker (e.g. Blob bindings). This feature can be turned on by setting FUNCTIONS_WORKER_SHARED_MEMORY_DATA_TRANSFER_ENABLED to true (PR: #816, thanks @gohar94)
• Added a new worker interface to allow third-party library integration into Python Worker. Third-party library developers can now integrate with Azure Functions by implementing lifecycle hooks in azure.functions.FuncExtensionBase or azure.functions.AppExtensionBase. This feature can be turned on by setting PYTHON_ENABLE_WORKER_EXTENSIONS to true. It is enabled in Python 3.9 by default. (PR: #815)

Release 1.1.12

• Implemented capability to isolate worker dependencies (#794)
  • New Experiment feature flag introduced - PYTHON_ISOLATE_WORKER_DEPENDENCIES (default: False)
• Setting PTPTC to None for Py3.9 only (#791)
  • More info on PYTHON_THREADPOOL_THREAD_COUNT in the docs page
• Update Python SDK Version to 1.6.0 (#812)
• Adding updates to the log messages (#805)

Release 1.1.10

1. Add support for Python 3.9 on Windows

Release 1.1.9

1. Reduce Linux and macOS Python worker size by enabling manylinux2010 wheel in Python worker. (#782)
