Summary

This release fixes a bug related to RTDS runtime guard override removal and introduces new opt-in features for monitoring HTTP/2 header statistics and limiting cookie header size.

Migration Steps

  1. To enable HTTP/2 header histograms, set the runtime feature flag envoy.reloadable_features.http2_record_histograms.

✨ New Features

  • Added opt-in histograms for HTTP/2 header statistics (header-entry count, header-map byte size, reassembled cookie header length, and individual cookie header count). Enable with envoy.reloadable_features.http2_record_histograms.
  • Added envoy.reloadable_features.http2_max_cookies_size_in_kb to limit the size of the reassembled cookie header (default is no limit).

🐛 Bug Fixes

  • Fixed RTDS runtime guard override removal so deleting an override restores the process-wide runtime guard value to the default value.
