The 10.26.1 release focuses on reliability for Python tasks and packaged integrations. Scheduled tasks and integrations that failed after the upgrade to Swimlane 10.26.0 now complete without a timezone error.

# Addressed Issues

- **Python Tasks and Packaged Integrations Failed With a Timezone Error** — Fixed an issue where scheduled Python tasks and packaged integrations (such as Microsoft Exchange Email) failed with a `RuntimeError: Unable to find any timezone configuration` when calling `pendulum.now()`. The `swimlane-tasks` container has been updated to include default timezone configuration (`TZ=UTC`), ensuring all Python scripts and packaged plugins execute reliably without requiring manual timezone initialization.
