Elgg vs SiYuan: at a glance
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 security-only patches. The recent entries are small — single-commit gatekeeper fixes, a CKEditor licensing version correction, terse 'small security update' notes — and contributor counts are in the low single digits, with the same one or two maintainers on nearly every release. The 7.0 line has already settled into patch mode.
What is SiYuan?
SiYuan's 3.8 branch turns a local-first notebook into an agent-readable knowledge store.
SiYuan publishes near-daily alpha tags whose notes are cumulative, so each release restates the previous one's feature list and appends what is new. The 3.7.4 line was pure enhancement work — Android and HarmonyOS parity, export fidelity, Pandoc packaging, drag-and-drop and font handling. The 3.8.0 line, opened on 4 August, carries four genuinely new features that had no predecessor in 3.7.4: OIDC authentication, an AI Agent, semantic search via embeddings and reranking, and MCP support.
Elgg vs SiYuan: editorial side-by-side
Elgg
5.0COLLAB
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 security-only patches. The recent entries are small — single-commit gatekeeper fixes, a CKEditor licensing version correction, terse 'small security update' notes — and contributor counts are in the low single digits, with the same one or two maintainers on nearly every release. The 7.0 line has already settled into patch mode.
◆ Where it's heading
This is a mature project maintaining a stable base rather than pushing new capability. The pattern of paired 7.0.x/6.3.x releases on the same day indicates a deliberate backport discipline, keeping the previous major line safe for deployments that haven't migrated. Nothing in the changelogs points toward new features; the substantive work visible here is the 7.0.1 cleanup batch that shook out post-major-release regressions in theming, discussions, and Safari script loading.
◆ Prediction
Expect the alternating pattern to continue — 7.0.x patch releases as issues surface, with matching 6.3.x security backports — until a 7.1 cycle opens. The entries give no indication of when that might be.
SiYuan
6.3COLLAB
SiYuan's 3.8 branch turns a local-first notebook into an agent-readable knowledge store.
◆ Current state
SiYuan publishes near-daily alpha tags whose notes are cumulative, so each release restates the previous one's feature list and appends what is new. The 3.7.4 line was pure enhancement work — Android and HarmonyOS parity, export fidelity, Pandoc packaging, drag-and-drop and font handling. The 3.8.0 line, opened on 4 August, carries four genuinely new features that had no predecessor in 3.7.4: OIDC authentication, an AI Agent, semantic search via embeddings and reranking, and MCP support.
◆ Where it's heading
The mobile and export grind continues underneath, but the branch cut is where the direction changed. Semantic search plus MCP means the vault becomes queryable by meaning and reachable by external agents, while OIDC is the first real answer for multi-user or organizational deployment — a notable turn for a product built around single-user local storage. The alpha.3 addition of LAN peer-assisted sync acceleration points the same way: sync is being optimized for several devices, or several people, on one network.
◆ Prediction
Expect the 3.8 alphas to keep layering onto the AI Agent and MCP surfaces — most likely which blocks or notebooks an agent may read, since OIDC arriving in the same release implies identity is about to gate access rather than just login.
