LibrePhotos vs Mattermost: at a glance
What is LibrePhotos?
LibrePhotos 1.6 redesigns the app and admits its Docker images sent usage data to Microsoft.
LibrePhotos went from 1.2.0 to 1.6.0 between late September and November 9. Releases 1.3 to 1.5 unified tagging and search on OpenCLIP, wrote edits back to files and added library and per-person sharing. Release 1.6.0 redesigns every page, puts face review one click from the People page, caps automatic tags at five confident ones, adds a year-in-photos recap, and fixes security problems in sharing and user management. It also discloses that the 1.5.0 and 1.5.1 Docker images sent model and hardware telemetry to Microsoft, and now keeps error reports on the server until an admin shares them.
What is Mattermost?
Mattermost v12 adds device and channel attributes to its access policies.
Mattermost v12 has arrived in three parts: agents that act with the requesting user's access and leave audit trails, Cross Guard for managed transfers across security domains, and now policy attributes that describe the user, device and channel. Access rules can evaluate the situation of a request, not just the identity behind it. The audience is defense and regulated buyers.

LibrePhotos
5.0COLLAB
LibrePhotos 1.6 redesigns the app and admits its Docker images sent usage data to Microsoft.
◆ Current state
LibrePhotos went from 1.2.0 to 1.6.0 between late September and November 9. Releases 1.3 to 1.5 unified tagging and search on OpenCLIP, wrote edits back to files and added library and per-person sharing. Release 1.6.0 redesigns every page, puts face review one click from the People page, caps automatic tags at five confident ones, adds a year-in-photos recap, and fixes security problems in sharing and user management. It also discloses that the 1.5.0 and 1.5.1 Docker images sent model and hardware telemetry to Microsoft, and now keeps error reports on the server until an admin shares them.
◆ Where it's heading
The cadence has held at roughly one feature release every two weeks, with each one aimed at families sharing one server rather than single users. The 1.6 telemetry disclosure and opt-in error sharing show privacy defaults becoming part of the release notes, not just security fixes.
◆ Prediction
Expect a 1.6.x patch soon given the pattern of quick fixes after each minor release, and continued work on face review and multi-user sharing.
Mattermost
6.3COLLAB
Mattermost v12 adds device and channel attributes to its access policies.
◆ Current state
Mattermost v12 has arrived in three parts: agents that act with the requesting user's access and leave audit trails, Cross Guard for managed transfers across security domains, and now policy attributes that describe the user, device and channel. Access rules can evaluate the situation of a request, not just the identity behind it. The audience is defense and regulated buyers.
◆ Where it's heading
After five weeks of zero-trust and resilience essays, Mattermost is shipping the controls those essays described, one v12 component per post. Policy attributes tie the agent permissions and Cross Guard pieces into a single access model.
◆ Prediction
Expect further v12 component posts or a point release with configuration details; the entries so far are announcements with little technical depth, so the rollout schedule is unclear.
