What is HumHub?

HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.

The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.

What is Outline?

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

5.0

HumHub's public feed carries only betas, and 1.19's is still about surviving the upgrade.

◆ Current state

The four releases visible here are all pre-release: 1.19.0-beta.2 and beta.1, and 1.18.0-beta.6 and beta.5 before them. The 1.19 line is dominated by upgrade-path and data-integrity repair — a foreign key violation aborting the comment content_id migration on databases with orphaned rows, fatal errors when purging content whose underlying record was gone, and in beta.2 a fatal SCSS build loop left behind when the 1.19 move of static/themes into protected/humhub stranded an empty theme skeleton. Beta.2 also fixes a real leak: activities from private spaces appearing in the summary mail and dashboard of users holding only a pending invite or join request.

◆ Where it's heading

The 1.19 cycle is being spent making the migration survivable on real installations rather than adding capability, which is the usual shape when a schema and directory-layout change meets databases and webroots that have accumulated years of drift. Beta.2 extends that into the installer itself, where an unreachable database was offering to re-set-up a live instance during a transient outage. The permission and visibility fixes point the same way: tightening authorisation and content boundaries is cleanup of an existing model, not an extension of it.

◆ Prediction

Only beta tags appear in this feed, so a 1.19.0 stable is the obvious next milestone, but nothing here dates it. The beta.1-to-beta.2 gap of about a month is a faster rhythm than the roughly six months between the 1.18 and 1.19 betas.

6.3

Outline goes browser-native for AI agents with WebMCP, accelerating its bet on agentic knowledge management.

◆ Current state

Outline has been shipping steadily across two tracks: UX refinements (split view, profile hover cards, task list improvements) and an increasingly serious MCP/agentic integration surface. The April MCP expansion added patching, moving, deleting, and inline comment tools. The September WebMCP drop goes further: in-browser AI agents can now discover and call Outline's structured tools directly through document.modelContext, requiring no server-side MCP connection. That makes Outline one of the first knowledge tools to adopt the browser-native agent discovery standard.

◆ Where it's heading

Outline is positioning itself as an agent-native knowledge base rather than just a polished wiki. The pattern across the last several releases is deliberate: MCP support expanded significantly in April, Open Knowledge Format export added portability in September, and WebMCP makes the agent integration surface browser-accessible. The OKF export is also a meaningful portability move — structured markdown bundles that survive outside Outline reduce lock-in risk and could attract teams evaluating it against more closed alternatives.

◆ Prediction

Outline will likely expand the WebMCP tool surface — the April MCP work gave them a solid set of structured tools to expose, and WebMCP makes those available without setup friction. Expect more agent-facing capabilities (summarization, cross-document linking, task extraction) rather than another round of baseline UX polish.
