What is Elgg?

A social-networking engine in careful maintenance across two supported branches.

Elgg is running a two-branch release cadence: a 7.0.x line taking bug fixes and a 6.3.x line receiving backports. The recent pairs shipped within two hours of each other — 7.0.5 carrying a single performance fix that stops likes generating ajax response data for unsupported entities, while 6.3.8 carries the longer list: improved sanitization of installer config values, a valid client IP for the core, embedded-image handling in notification emails, mute-option validation, and a permission check before a profile header image can be changed. Contributor counts stay in the low single digits with the same one or two maintainers on nearly every release.

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.

5.0

A social-networking engine in careful maintenance across two supported branches.

◆ Current state

Elgg is running a two-branch release cadence: a 7.0.x line taking bug fixes and a 6.3.x line receiving backports. The recent pairs shipped within two hours of each other — 7.0.5 carrying a single performance fix that stops likes generating ajax response data for unsupported entities, while 6.3.8 carries the longer list: improved sanitization of installer config values, a valid client IP for the core, embedded-image handling in notification emails, mute-option validation, and a permission check before a profile header image can be changed. Contributor counts stay in the low single digits with the same one or two maintainers on nearly every release.

◆ Where it's heading

This is a mature project maintaining a stable base rather than pushing new capability, and the balance between the branches is worth noting: the older 6.3 line is receiving more substantive hardening than the current 7.0 line, which has already settled into single-commit patches. That is what a project looks like when most of its deployments have not migrated yet. The 6.3.8 items — input sanitization, permission validation before a mutating action — are the security-shaped fixes that earlier 6.3 releases summarised only as 'small security update'.

◆ Prediction

Expect the alternating pattern to continue: 7.0.x patches as issues surface, with matching 6.3.x backports carrying the hardening work, until a 7.1 cycle opens. The entries give no indication of when that might be.

P3.8

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.
