Scheduler 1.9.0-pl

Released on 2026-01-20

Released on 2026-01-20

This release combines all changes from the separate versions previously maintained by modmore and @biz87 (found on Modstore) into a single codebase.

Version 1.9 includes all updates from both forks up to January 20, 2026.

Major Changes:

* **Fork Unification:** Merged all features and fixes from the modmore and @biz87 forks to ensure a single, consistent version moving forward.

* **Recurring Tasks:** Tasks can now be set to repeat automatically after a successful run using the new automatic rescheduling feature. This was already possible in code, now also in the UI.

* **Retry System:** Added the ability for failed tasks to retry automatically. This includes new settings for the maximum number of retries and the delay between attempts.

* **Custom Notifications:** You can now customize the email template and subject line used for task failure alerts via system settings.

### General Improvements

* Fixed a race condition issue to ensure task statuses update correctly and safely if you have multiple triggers.

* Added database indexes to help the system select and run pending tasks faster.

* Improved memory management by cleaning up resources after every task execution.

* Updated error handling to be more robust, catching both system errors and basic exceptions.

* Improved compatibility with MODX 3 namespaced processors.

* Fixed a timing bug where tasks were occasionally rounded up to the next minute incorrectly.

* Added a new setting to limit how many tasks are processed in a single run.

### Interface and Developer Updates

* Added the retry count to the task history grid.

* Added fields for max retries and retry delay to the task edit window.

* Fixed the component icon in the main menu.

* Made sTaskRun constants public and standardized the code style across the package.

* Added a simpler way to set task keys when scheduling tasks through code.
