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 SiYuan?

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

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.

6.3

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

◆ Current state

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

◆ Where it's heading

This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.

◆ Prediction

The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
