Releases XenForo 2.3.8 Full Stable Version has been released XenForo 2.3.8

XenForo 2.3.8 is a stability-focused point release, but it also introduces several developer/admin-facing features (notably better CLI tooling, template syntax improvements, and new API capabilities).

Notable new features​

• Retina thumbnails: XenForo now generates two attachment thumbnail sizes (normal + 2x) so compatible high‑DPI devices automatically display sharper thumbnails.
• Template syntax now supports the PHP-style null coalescing operator , letting templates fall back across multiple values more cleanly.??
• REST API support for Search: new API endpoints allow performing searches and retrieving search results via the XenForo REST API.

New CLI / developer tooling​

• New CLI command lists installed add-ons (with filters like active/inactive, JSON output, and verbose mode).xf:addon-list
• New scaffolding commands help developers generate common constructs (entity, repository, controller, listener, CLI command, etc.) with less manual setup.xf-make

Selected improvements and fixes (high impact)​

• Authentication/security: multiple passkey improvements (e.g., allow passkey creation on local hosts; require re-auth before passkey changes; delete passkeys when the user is deleted; count failed passkey logins toward the failed login limit; allow passkeys in place of password confirmations).
• Email: fixes related to DKIM signing and List-Unsubscribe headers, and improved bounce handling (e.g., Gmail inactive inbox treated as hard bounce; multi-digit status codes handled).
• Search: stricter search input handling and earlier errors for overly long keywords; improved filtering behavior in some areas (e.g., profile postings tab behavior and member thread search filters).
• Performance/consistency: add-on manager performance improvements with many add-ons installed; some query reduction/caching tweaks (e.g., caching user online counts in-request).

Templates touched (useful for style/add-on maintainers)​
