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 gave AI assistants write access to the wiki, then spent months on the human side.
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.
HumHub vs Outline: editorial side-by-side
HumHub
5.0COLLAB
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.
Outline
2.5COLLAB
Outline gave AI assistants write access to the wiki, then spent months on the human side.
◆ Current state
The April MCP expansion is the structural change in this window: assistants can patch documents, move and delete documents and collections, work with attachments, and create and resolve inline comments. Everything since has been human-facing and smaller — request-access flows for documents members cannot open, email subscriptions to publicly shared documents with change summaries, task list and checkbox handling in the editor, and profile cards on avatar hover.
◆ Where it's heading
Two audiences are being served in sequence. The MCP work moved assistants from reading the knowledge base to editing it, including the collection structure itself. The releases after it close ordinary gaps in how people find, follow and get into documents — which is what a wiki needs before more of its edits arrive from automation. Release cadence is roughly monthly with entries that describe outcomes rather than changelogs.
◆ Prediction
Expect the human-facing polish to continue at its current pace, with any next structural move likely extending the MCP surface further into permissions and collection management, since that is where the existing tools stop.
