April 2025 highlights in facebook/igl: delivered two focused improvements enhancing correctness for long-name handling and performance for CRC32 computation. Added a dedicated test for NameHandle long-string handling to validate toString and getCrc32 behavior for strings longer than one character. Refactored the CRC32 path to a loop-based template implementation, reducing recursion, lowering stack usage, and improving throughput. These changes strengthen data path reliability and performance, delivering tangible business value with maintainable code.
