v1.4.25

October 06, 2026

  • Universal WordPress & HTTP Cacheability Gatekeeping: eliminated brittle regex exclusions in favor of universal cacheability gatekeeping based on core WordPress and HTML5 specifications.
  • Universal Visitor Miss Gatekeeping: requests defining DONOTCACHEPAGE, returning non-200 status codes, 404, search, feeds, embeds, trackbacks, password-protected posts, or headers declaring Cache-Control: no-store/no-cache or X-Robots-Tag: noindex are never enqueued into the preload queue.
  • Preloader Crawler Non-Cacheable Outcome Classification: when a 200 OK crawler response is not cacheable, it is marked skipped (non_cacheable) instead of failed, eliminating retry loops.
  • Preload Output Buffer & Bypass Signaling: ensured PageCache buffering starts on crawler requests to emit X-OptiWave-Cache: BYPASS headers and inline markers when page caching is not applicable.

October 05, 2026

  • Zero-Downtime Atomic Preload: removed premature pre-request cache file deletion, serving visitors continuously with sub-millisecond cache hits until atomic swap via rename.
  • Timestamp-Based Cache Verification: verifies that preloaded cache files on disk have mtime >= request_started – 2, ensuring newly written files are validated without destroying existing assets.

v1.4.23

October 05, 2026
