Full Changelog: v0.6.0...v0.7.0

v0.6.0

What's Changed

This version brings a lot of new and powerful APIs to the SDK.

The main change that v0.6 brings is enabling the integration of Dispatch in applications that are not based on FastAPI. The top-level dispatch package can now be used to create vanilla Dispatch applications:

import dispatch

# The .function decorator is available on the top-level package to
# declare functions that can be orchestrated by the scheduler.
@dispatch.function
def greet(who: str):
    ...

# The .run function runs the main event loop interacting with the
# scheduler. It takes an optional initialization function that will
# be called right before entering the event loop.
dispatch.run(lambda: greet.dispatch('me'))

New features

• Dispatch without FastAPI by @achille-roussel in #154

Other changes

• Remove mock server entry point by @chriso in #151
• Don't print verification key warning when running under Dispatch CLI by @chriso in #152
• Extract new proto fields by @chriso in #153

Full Changelog: v0.5.1...v0.6.0

v0.5.1

What's Changed

This version adds multiple bug fixes, including one that prevented dispatch functions from running concurrently within a single application instance (distributing concurrent calls across multiple instances was unaffected).

Other changes

• FastAPI: run Dispatch functions in a thread executor by @chriso in #146
• Add experimentation Lambda integration by @Pryz in #142
• Don't pickle coroutine state twice by @chriso in #148
• Bump cibuildwheel version to fix PyPI publish issue by @chriso in #149

Full Changelog: v0.5.0...v0.5.1

v0.5.0

What's Changed

This version introduces a new Reset error type, which when raised or returned, replaces the function being run by a different call.

New features

• add special Reset class to implement tail calls by @achille-roussel in #145

Full Changelog: v0.4.2...v0.5.0

v0.4.2

With this patch release, programs that run on Python 3.8 can now use Dispatch.

What's Changed

Other changes

• Python 3.8 support by @chriso in #143
• Don't test ./examples by default by @chriso in #144

Full Changelog: v0.4.1...v0.4.2

v0.4.1

This patch release brings compatibility with Python 3.9 and 3.10.

Prior to this update, the Python SDK for Dispatch was only compatible with Python 3.11+, which caused a lot of issues due to default Python installations often being older on OSX and Ubuntu (usually 3.9). This caused a lot of friction for users who tried Dispatch but didn't have a supported version pre-installed.

What's Changed

Bug fixes

• v0.4.1: fix build by @achille-roussel in #139
• Add MANIFEST.in by @chriso in #141

Other changes

• Minor UX improvements by @chriso in #138
• Python 3.10 support by @chriso in #136
• Python 3.9 support by @chriso in #140

Full Changelog: v0.4.0...v0.4.1

v0.4.0

This is an important release with new concurrency APIs to compose more advanced applications powered by Dispatch.

The release also includes new default integrations for errors raised by popular services like Slack and OpenAI, so dispatch functions can automatically handle retries when executing requests to those APIs.

What's Changed

New features

• Concurrency primitives: any, all, race by @chriso in #131
• Remote endpoints by @chriso in #134
• Slack integration by @chriso in #132
• OpenAI integration by @chriso in #133

Other changes

• Fix registration of synchronous functions by @chriso in #129
• mock server: show more info when a call fails by @chriso in #128
• Promote docopt dependency by @chriso in #130
• Promote httpx dependency by @chriso in #137

Full Changelog: v0.3.0...v0.4.0

v0.3.0

v0.3.0 introduces a new SDK feature called batch, allowing you to build a batch of functions to be dispatched and executed concurrently.

@dispatch.function
def funcA(): ...

@dispatch.function
def funcB(someargs): ...

batch = dispatch.batch()
batch.add(funcA)
batch.add(funcB, someargs)

batch.dispatch()

Take a look at the documentation to learn about the different SDK features: Workflow as code!

Happy building!
