What is Flarum?

Flarum's 2.0 has been in release-candidate territory for most of a year.

Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.

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.

Flarum's 2.0 has been in release-candidate territory for most of a year.

◆ Current state

Flarum is an open-source forum framework whose entire recent release history is the 2.0 train — beta.8 in March, then five release candidates from April through July. The candidates ship on a three-to-six week rhythm, and most of them publish nothing beyond a pointer to the changelog file in the tag. The last releases carrying visible detail were the earlier ones, where the work was database and rendering performance plus extension-compatibility fixes.

◆ Where it's heading

The substance that is visible points at making large forums viable: eliminating N+1 queries on the discussion list, adding a composite index to fix slow unread-notification counts, and caching scheduler timestamps. Those are the changes a forum makes when instances have outgrown the original query patterns. The steady RC cadence with no beta regression suggests a stabilisation grind rather than continued feature work — but the opaque release notes make the remaining scope hard to read from outside.

◆ Prediction

A 2.0 stable release is the obvious next step, though five candidates without a published scope makes the timing unclear. Watch whether rc.6 arrives on the same three-to-six week spacing or the gap widens.

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.
