Feature Release

Features

• Advertise support for Python-3.13, although no code changes were made to support it. (#434)
• Add kill_on_cancel kwarg to run_sync. The alias cancellable will remain indefinitely. (#437)
• Add cache_scope(), an async context manager that can override the behavior of trio_parallel.run_sync() in a subtree of your Trio tasks with an implicit WorkerContext. (#455)

Deprecations and Removals

• Stop advertising support for Python-3.8, although no code changes were made to break it. (#434)
• Removed deprecated atexit_shutdown_grace_period. Use configure_default_context to configure the default context shutdown grace period. (#435)

Bugfix release

Bugfixes

• Ensure worker processes are eagerly reaped after a rare race condition edge case. (#436)
• Fix a usage of a removed internal trio function in the test suite. (#444)

Bugfix release

Bugfixes

• Fix a regression induced by trio-0.27.0 that causes worker contexts to crash on exit if they happen to wait for jobs to finish. (#432)

Bugfix release

Bugfixes

• Fixed a rare race condition during cleanup that could trigger unraisable error tracebacks. (#398)
• Made several internal changes that may make compatibility with future Trio versions more stable (#412)

Bugfix release

Bugfixes

• Resolved a deprecation warning on python 3.12. (#380)

Deprecations and Removals

• Although python 3.7 has not been specifically broken, it is no longer tested in CI. (#389)

Feature release

Features

• The behavior of the default context is now fully configurable, superseding atexit_shutdown_grace_period (#328)

Bugfixes

• Use tblib lazily to pass tracebacks on user exceptions. Previously, tracebacks would only be passed on the built-in python exceptions. (#332)

Feature release

Features

• Add type hints for run_sync (#322)
• Use tblib to enable pickling of tracebacks between processes. Mainly, this preserves context of exceptions including chained exceptions. (#323)

Bugfixes

• Prevent Ctrl+C from inducing various leaks and inconsistent states. (#239)
• Cleaned up names/qualnames of objects in the trio_parallel namespace. (#291)

Deprecations and Removals

• Removed python 3.6 support (#236)

Major Release

Bugfixes

• Fixed a hang on failed worker subprocess spawns that mostly occurred upon accidental multiprocessing recursive spawn. #167
• Fixed a hang on Windows when trying to use WorkerContext.run_sync in sequential and concurrent Trio runs. #171

Improved Documentation

• Revamped documentation with tested examples. #168

Prerelease Postrelease

Updates trove classifiers and loosens CFFI requirement.

Feature Prerelease

With this release I consider the project "feature complete" although, as a beta release still, I would be open to PRs for new features with a strong motivation.

• Added an API to view statistics about a WorkerContext, specifically counting idle_workers and running_workers. #155
