Changelog for package autoware_utils_diagnostics

1.8.0 (2026-06-10)

• perf(autoware_utils_diagnostics): drop per-cycle shrink_to_fit in clear() (#106) clear() called values.shrink_to_fit() right after values.clear(), releasing the underlying buffer every cycle and forcing the next add_key_value() push_backs to reallocate on hot localization callbacks. Drop the shrink_to_fit() call so the buffer capacity is retained across cycles; .clear() and the level/message resets are unchanged, so published messages are output-identical. Add a pub/sub characterization test that pins the observable behavior across clear() cycles (value contents/order, level, message, dedup), proving the removal is behavior-preserving.

• feat: make DiagnosticsInterface's node argument as template type (#102)

  • templatize DiagnosticsInterface
