Worked on the rclone/rclone repository to enhance clarity and consistency in the naming of the Glacier storage class within the S3 backend. Delivered a targeted feature that updated all references from “Glacier storage class” to “Glacier Flexible Retrieval storage class” across both Go code and Markdown documentation. This change aligned the terminology with the actual retrieval option, reducing potential user confusion and improving support efficiency. Focused on backend development and documentation, the work ensured that code and documentation remained synchronized, making it easier for users to understand available storage options and for maintainers to provide accurate guidance and support.
