Rocket.Chat vs PhotoPrism: at a glance
What is Rocket.Chat?
All the substance lands in rc.0 — this cycle it's phishing-resistant MFA
Rocket.Chat publishes a release candidate per patch, and the shape is consistent: rc.0 carries the actual changes and every candidate after it is a Meteor version bump with dependency updates. In the 8.7 cycle, rc.0 introduced phishing-resistant multi-factor authentication via a server-side OAuth flow, plus a current field on DeviceManagementSession so the sessions endpoint can flag the caller's own active session. The 8.6 candidates in this window carry nothing but version bumps. Engine versions are pinned across the line at Node 22, Deno 2.3 and MongoDB 8.
What is PhotoPrism?
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.

All the substance lands in rc.0 — this cycle it's phishing-resistant MFA
◆ Current state
Rocket.Chat publishes a release candidate per patch, and the shape is consistent: rc.0 carries the actual changes and every candidate after it is a Meteor version bump with dependency updates. In the 8.7 cycle, rc.0 introduced phishing-resistant multi-factor authentication via a server-side OAuth flow, plus a current field on DeviceManagementSession so the sessions endpoint can flag the caller's own active session. The 8.6 candidates in this window carry nothing but version bumps. Engine versions are pinned across the line at Node 22, Deno 2.3 and MongoDB 8.
◆ Where it's heading
The work visible here is identity and session control rather than messaging features — who is authenticated, how strongly, and which device is asking. Phishing-resistant MFA and caller-session identification are both procurement concerns for the regulated and self-hosting buyers Rocket.Chat competes for, and they arrive together. The release-candidate pattern means the feed's cadence overstates activity: six entries in this window represent two substantive changes.
◆ Prediction
Expect the 8.7 line to reach general availability with the MFA flow as its headline, and further session and device-management controls to follow on the same identity track.

3.8COLLAB
PhotoPrism swapped in an ONNX vision pipeline, then opened the library to 360° media at 16K.
◆ Current state
Two substantial releases in ten weeks moved the product on both axes it cares about. May replaced the legacy Pigo face detector entirely with an ONNX-based pipeline, made vision.yml accept model identifiers from Hugging Face, Ollama and OpenAI-compatible catalogs, and modernised media handling with Vulkan transcoding, a native HEIC/AVIF reader and layered TIFF and PSD support. July added interactive equirectangular 360° photos and video, raised the thumbnail and video ceiling to 16K, and put an inline multi-page PDF viewer in the app.
◆ Where it's heading
The AI work has moved from bundled TensorFlow models to a pluggable pipeline where the model catalog is configuration, not a build artifact — Ollama, OpenAI and Hugging Face identifiers all resolve through the same file. In parallel the media layer keeps absorbing formats other libraries push out to external tools: PSD, layered TIFF, PDF, and now 360°. PhotoPrism is positioning as the thing you point at a mixed archive, not just a photo folder.
◆ Prediction
Expect the format expansion to continue and the vision configuration to keep broadening its provider surface, with the accessibility section added in July likely to grow into a fuller pass.
