Version 1.1.7

  • kernel controller class detects terminated kernel process while waiting for an evaluation result instead of hanging.

Version 1.1.5 and 1.1.6

  • update Wolfram Language code with latest addition from 12.3.
  • fix various deprecated naming convention in class names.

Version 1.1.4

  • Async cloud evaluator based on aiohttp now use certifi to create a default SSLContext if none is provided. Other cloud evaluator are based on the requests module which also uses this library.
  • Updating dependency list accordingly in setup.py. certifi was already listed as a requests dependency, so this should have no direct impact on user site package.

Version 1.1.3

  • Update asynchronous evaluator classes. Remove the loop parameter. Most optional loop parameters are deprecated in the Python standart library asyncio and in most libraries, mainly because it is misleading and lead to misuses and bugs. The loop parameter is useful when instantiating asynchronous evaluators outside the scope of an event loop. It's implementation was not good enough and was relying on usages deprecated in 3.8.
  • Removing four asynchronous generators in asynchronous evaluation result classes: iter_messages, iter_messages_name, iter_messages_tuple and iter_output. These coroutines are only working on python 3.6+ and are not critical enough to drop support for 3.5. Asynchronous properties: messages, messages_name and output provide the same information.

Version 1.1.2

  • Fix a backward incompatible change introduced in 12.1. Make sure the library works with any kernel version starting with 11.3.
  • Minor changes and tweaks.

Version 1.1.0

  • WXF deserialization maps List to tuple, was list before for two reasons. List and tuple are immutable. tuple contrary to list are hashable object and as such can be keys in dict.
  • WXF deserialization maps numeric arrays to NumPy arrays. Numpy being a pre-requisite of the library, and lazily loaded, this change will boost performances while causing very little trouble, if any.
  • Fix bug in WolframLanguageSession that was preventing Python interpreter from exiting.
  • Add new class PackedArray, a wrapper on top of NumPy ndarray. Instances of PackedArray are serialized as... WL packed array (!). This fixes the issue of having a WL packed array (say the output of Range[3]), being serialized to a ndarray (arange(3)), and send back to the kernel as a NumericArray.
  • Use black code formatter.

Version 1.0.2

  • Add two new optional flags to test command called -x or --xml and -d or --xml-dir. It produces an xml output of the test results using the unittest-xml-reporting library. -d expects the filepath of the output directory, default is test-reports. Also add -v or --verbosity to control the verbosity option of the test suite. Check python run.py test -h for more info.

Version 1.0.1

  • Bug fix in WXFConsumer.
  • Update some URLs.

Version 1.0.0

  • Introducing a new class WolframKernelController. Major code change to ensure ZMQ sockets are isolated in a given thread. Add a new controller class, a Thread, that own the sockets connected to the kernel. Interaction with this thread is done through a Queue.
  • Merge WolframLanguageFutureSession into WolframLanguageSession. All evaluate methods have a future counterpart.
  • Merge WolframCloudFutureSession into WolframCloudSession. Add relevant future methods.
  • Rename WolframAPICall method add_parameter to set_parameter since setting is exactly what it does.
  • Result of API call, the WolframAPIResponse family of classes, now automatically deserialize the response content using the content-type, if it's WXF or JSON. The content type remains accessible in the response member of those classes.
  • rename evaluator parameters STARTUP_READ_TIMEOUT to STARTUP_TIMEOUT, and TERMINATE_READ_TIMEOUT to TERMINATE_TIMEOUT.
  • CPU consumption reduced to ~1% with the latest ZMQLink version.
  • Local session checks for the Wolfram Kernel version at startup and fails with a specific message.
  • Local session supports instant logging for messages, with severity warn, and prints, with severity info. This only works for kernel with a kernel_loglevel set on initialization, and allows real time feedbacks, even if the kernel evaluation is not yet completed.
  • Change mapping of WXF symbols to Python objects. The only symbols that are deserialized to Python objects are the one that round trips: Null, True, False. Pi and None are no more deserialized to, respectively, math.pi and None.

Version 1.0.0.dev4

  • Inconsistent class name WolframCloudSessionFuture replaced with WolframCloudFutureSession.
  • Rework completely Dispatch class. Add a Dispatch instance called wolfram_encoder representing the multi dispatch function that encodes Python object.
  • Add an entry point allowing new encoders to be registered as separated libraries (plugins).
  • Add support for pandas classes: Series and DataFrame.
  • Extend support for NumPy numbers.
  • Local evaluators can be initialized without a Wolfram Kernel path, in which case default paths are scanned to find the most recent product.

Version 1.0.0.dev3

  • Add CHANGELOG.md to the repository to help users track the changes.
  • Major refactoring of the evaluation module.
    • add base classes for synchronous and asynchronous evaluation, specifying the evaluation scheme.
    • add cloud session implementation based on event loop using the aiohttp library.
    • rename asynchronous session based on future module from WolframCloudAsyncSession to WolframCloudSessionFuture.
    • add new implementation of WolframCloudAsyncSession based on asyncio and coroutines.
  • Cloud session named option authentication renamed credentials.
  • Significant improvement of PIL.Image support. Speed up serialization and deserialization of images, and add support for more input formats.

Version 1.0.0.dev2

First released version of the library as a release candidate.
