@@ -82,6 +82,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - 🗄️ **Configurable storage local cache.** Administrators can now disable persistent local caching for cloud-backed uploads with the "STORAGE_LOCAL_CACHE" setting, reducing local disk usage by cleaning temporary upload copies after processing. [Commit](https://github.com/open-webui/open-webui/commit/8172c7e3d56918d1372be06b9369b58a3a88f6b1)
 - 🚪 **Back-channel logout.** OpenID Connect providers can now trigger centralized logout through the "ENABLE_OAUTH_BACKCHANNEL_LOGOUT" setting, helping administrators invalidate user sessions more reliably across connected devices. [Commit](https://github.com/open-webui/open-webui/commit/0dd9f462ffb2f160bc4aebad182047f41874d250)
 - 🛡️ **Expanded security header controls.** Administrators can now configure additional browser security headers, including "CONTENT_SECURITY_POLICY_REPORT_ONLY", "CROSS_ORIGIN_EMBEDDER_POLICY", "CROSS_ORIGIN_OPENER_POLICY", and "CROSS_ORIGIN_RESOURCE_POLICY", for stricter and more flexible deployment hardening. [Commit](https://github.com/open-webui/open-webui/commit/f246a66810fa4995d9494da3599c0fb297fb0213)
+- 🖼️ **Image MIME fallback option.** Administrators can now enable "ENABLE_IMAGE_CONTENT_TYPE_EXTENSION_FALLBACK" so image-to-base64 conversion can still detect common image types by file extension when MIME metadata is missing, improving compatibility on minimal container images and older file records. [Commit](https://github.com/open-webui/open-webui/commit/5127354b3eb4eaa71bc4ad68da69729e2196e7a4)
 - 🛡️ **Public sharing permissions.** Public channels, models, notes, prompts, and tools now respect allowed access grants more consistently, helping administrators control who can share content more safely. [Commit](https://github.com/open-webui/open-webui/commit/9d3e0637c86292b8b92e7607097a83f1075d7cd8)
 - 🆔 **Skill lookup by ID.** Skill instructions now include each skill’s ID, and the skill viewer now finds skills by ID in a case-insensitive way so attached skills are identified more reliably in chats. [Commit](https://github.com/open-webui/open-webui/commit/65ee771fd0d62d785ecbcf189e3f5b63858c11e6)
 - 🏷️ **Source context metadata.** Retrieval source context now includes each source’s resource type and resource ID metadata, helping downstream model workflows preserve richer source identity during processing.
