+
+This document summarizes OpenMP standards support in Flang. The information is only provided as a guideline. The
+TODOs/Not Yet Implemented messages emitted by the compiler for unimplemented features should be treated as authoritative.
+As of March 2025, standards support is provided upto OpenMP 4.0. We are actively working towards supporting OpenMP 4.5, OpenMP 5.* and OpenMP 6.0.

I know that it has been requested to have a date in the document, but I would treat the modification date of the file in the commit log as being more accurate than the date in the document that could easily be missed when updating the file (plus, it does not protect us from the document becoming outdated over time).
