This release brings a built-in Markdown editor, with both visual and source modes, plus support for tables, task lists, images, code blocks, file locking, and unsaved-change protection.

It also adds optional trash retention, storage quota synchronization via LDAP/OIDC, improved file editing and search, stronger full-text indexing, better text file detection, and safer uploads.

On the security side, Sync-in 2.3 improves guest link isolation, makes trashed files read-only, and fixes CVE-2026-47684 by strengthening SSRF protection for remote URL downloads.
