⚠️ Potential issue | 🟠 Major

Replace placeholder release date before merge.

(dd MMM 2026) looks like a template placeholder and should be a concrete date in the final notes.

Verify each finding against the current code and only fix it if needed.

In `@docs/src/main/sphinx/release/release-481.md` at line 1, Update the release
header that currently reads "# Release 481 (dd MMM 2026)" to include the actual
release date instead of the placeholder; locate the header line in
release-481.md and replace "(dd MMM 2026)" with the concrete date string (e.g.,
"(08 Apr 2026)") so the top-level title shows the final release date.
