Release Notes: Item 2511-01

2026-2027 Regulatory Release (File Changes)

This is the first of two release items which comprise the 2026-2027 Regulatory release. This first item concerns new year-specific file definitions required for 2026-2027 Federal processing. The accompanying source code changes will be issued in release item 2511-02.

(Dictionary entries, traditionally delivered with the file changes, will be delivered with the source code changes for 2026-2027.)
