+== Release notes for {pipelines-title} General Availability 1.17.2
+
+With this update, {pipelines-title} General Availability (GA) 1.17.2 is available on {OCP} 4.12, {OCP} 4.14 through to 4.18.

+[id="fixed-issues-1-17-2_{context}"]
+=== Fixed issues
+
+* Before this update, the `skopeo-copy` task required you to explicitly set the `source_image_url` and `destination_image_url` parameters. This requirement prevented the use of the `images_url` workspace with a `url.txt` file for batch image copying. With this update, both parameters default to empty values and are excluded from strict validation, allowing the task to fall back to the `url.txt` method as intended.
+
+* Before this update, when you used matrixed tasks in a fan-out and fan-in pattern, the `PipelineRun` execution failed with the following error: `invalid result reference in pipeline task 'printer': unable to validate result referencing pipeline task 'platforms': task spec not found`. This issue occurred when a downstream task attempted to reference aggregated results from a matrixed task by using the following syntax: `$(tasks.<taskName>.results.<resultName>[*])`.
+With this update, {pipelines-shortname} correctly resolves and validates result references from matrixed tasks. This enables dynamic fan-out and fan-in task orchestration using arrays and matrix expressions without triggering validation errors.
+
+* Before this update, there was no upgrade path from {pipelines-shortname} 1.16.x to later versions. With this update, the issue is fixed.
