Dec 1, 2024December 2024: LitData feature documentation enhancement. Added README examples demonstrating how to filter illegal or unwanted data from datasets using LitData, including a boolean-function approach to select data by index and a try-except approach to skip entries that would cause processing errors. The update also bumps the LitData library version to reflect the changes. No major bugs fixed this month. This work improves data quality, accelerates user onboarding, and strengthens reliability of data processing pipelines for end users and downstream applications.
