8.0 – Coming soon 2026

• 🌱OptiMax OptiMax to maximize the page score.

7.9.1 – Sep 1 2026

• Core Aligned the runtime PHP and WordPress guards with the published minimum requirements.
• ESI Prevented Guest Mode pages from creating ESI subrequests when an integration registered its ESI hooks before Guest Mode detection.
• ESI Bound ESI execution to the signed query payload so POST parameters cannot replace validated block data.
• Image Optimize Fixed a fatal error when the WordPress HTTP fallback could not download an image.
• Image Optimize The image optimization callback is now verified by a QUIC.cloud signature instead of the source IP address, and every notified download location is validated before use.
• Image Optimize Successful callback retries now ignore rows already returned to the raw queue without blocking other live rows in the same batch.
• Image Optimize An image whose queued file can no longer be verified against its attachment is now dropped instead of being sent back for optimization, so it can no longer request optimization again on every cron run.
• Image Optimize Bounded and expired pending image-completion notifications without keeping the image pull cron running indefinitely.
• Image Optimize Optimized image downloads now use the WordPress safe HTTP API, refuse redirects, and validate each response before publication.
• Image Optimize Image pull notices now distinguish download, remote-service, and local-save failures.
• Cache Do Not Cache, Private Cached, Force Cache, Optimization and Lazy Load URI rules now compare the same query string against both spellings of a REST route, so a rule naming a query argument, or anchored to an exact address, applies to plain-permalink sites the same way it does elsewhere.
• Optimization Remote images, avatars, localized JavaScript, CSS/JS cache files, and Guest Mode lists now share bounded streamed downloads and atomic file publication.
• VPI Fixed queue-key collisions on plain-permalink sites and enforced the configured queue limit.
• Cloud Every QUIC.cloud callback — CDN status, error domains, IP validation and ping — is now verified by a QUIC.cloud signature rather than by the source IP address, and the source IP allow list has been removed. Activation, echo, account-link and CDN-enable signatures are now bound to their purpose and site.
• Cloud Added stable callback error codes so QUIC.cloud can distinguish retryable timestamp, storage and replay-cache-capacity failures from terminal authorization failures.
• REST Removed the legacy check_img diagnostic endpoint.
• API Removed the litespeed_is_from_cloud filter. Each callback is now authorized by its own signature instead of by a request-wide flag.
• API Added the litespeed_static_dir_htaccess filter so hosts can remove unsupported directives from the generated static-directory protection file. (vvvllll #1043)
• Avatar Prevented failed on-demand avatar downloads from redirecting visitors to the WordPress admin area.
