+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.
+Standards support is provided upto OpenMP 4.0 for now. It will be extended later for OpenMP 4.5, OpenMP 5.* and OpenMP 6.0.

Would it be worth putting in a date here, so there is some indication of how valid this sentence is?

As of March 2025, standards support is provided upto OpenMP 4.0. It will be extended later for OpenMP 4.5, OpenMP 5.* and OpenMP 6.0.
```

```
We are actively working towards supporting OpenMP 4.5, OpenMP 5.* and OpenMP 6.0.
