This [update](https://docs.photoprism.app/release-notes/#may-23-2026) introduces a redesigned [Info Sidebar](https://docs.photoprism.app/user-guide/organize/info-sidebar/) that lets you [edit metadata, albums, and labels](https://github.com/photoprism/photoprism/issues/4966) as well as [manually tag faces](https://github.com/photoprism/photoprism/issues/1548) without leaving the full-screen viewer. On the AI side, our ONNX-based face recognition pipeline has fully [replaced the legacy Pigo detector](https://github.com/photoprism/photoprism/issues/5508), and the [`vision.yml`](https://docs.photoprism.app/user-guide/ai/#visionyml-reference) configuration now accepts [mixed-case model names](https://github.com/photoprism/photoprism/issues/5594) so all identifiers from Hugging Face, Ollama, and OpenAI-compatible catalogs can be used.

Media handling has been thoroughly modernized: video transcoding now supports [Vulkan hardware acceleration via FFmpeg 8](https://github.com/photoprism/photoprism/issues/5592), images use a [native HEIC/AVIF reader](https://github.com/photoprism/photoprism/issues/5509) (with `libheif` upgraded to v1.21.2), and [layered TIFF and Adobe Photoshop PSD](https://github.com/photoprism/photoprism/issues/5383) files are now supported. Other highlights include [NOT & AND operators in the label filter](https://github.com/photoprism/photoprism/issues/5535), a [drag-and-drop file upload zone](https://github.com/photoprism/photoprism/issues/1216), [`zstd` compression](https://github.com/photoprism/photoprism/issues/5550) for faster page loads, [hardened WebDAV interoperability](https://github.com/photoprism/photoprism/issues/3541), and a new Ubuntu 26.04 LTS base image.

A big thank you to [everyone who contributed](https://docs.photoprism.app/developer-guide/) and [helped with testing](https://github.com/photoprism/photoprism/issues?q=is%3Aissue%20state%3Aopen%20label%3Aplease-test)! We hope you enjoy this release. 🌈💎✨
