The Joomla Project released Release Candidate 3 for Joomla 6.1 on April 13, 2026 — the final checkpoint before the stable version shipped on April 14, 2026. With a language freeze in effect at this stage, the project's message to the community was clear: it's time to test.

What RC3 Brings to Joomla 6.1

Because RC3 arrives after feature freeze, the changelog is intentionally narrow. The headline change is a single, focused improvement: dispatcher support was added to the jooa11y accessibility plugin, contributed by Harald Leithner. This update refines how the accessibility checker fires across the site, improving reliability for teams that rely on jooa11y as part of their content workflow.

The broader Joomla 6.1 feature set — built across three Alpha and three Beta releases since November 2025 — remains intact. Developers can review the full list of committed changes in the GitHub milestone.

For extension developers, the Joomla team published a detailed guide on potential backward compatibility issues in Joomla 6.1 — required reading before upgrading or testing extensions.

The Road to Joomla 6.1 Stable

The 6.1 cycle kicked off in late November 2025 and moved through three Alpha builds, three Beta builds, and three Release Candidates on a consistent fortnightly cadence:

How to Get Joomla 6.1 RC3

The release package was available directly from the official GitHub releases page. For those tracking the very latest commits, nightly build packages are updated every night.

Newcomers who want a quick way to explore a release without setting up a local environment can launch a free hosted Joomla 6 test site at launch.joomla.org — no server configuration required.

How the Community Can Help

The Joomla Project asked the community to focus on one thing before stable: testing. Extension developers in particular were encouraged to install their add-ons on an RC3 environment, verify compatibility, and report any issues at issues.joomla.org.

Developers could also join the extension development channel on Mattermost at joomlacommunity.cloud.mattermost.com to coordinate with the broader ecosystem.

Documentation contributions were also welcome. The developer manual at manual.joomla.org remains open for updates — particularly around the 6.0→6.1 migration path and new API changes introduced in this cycle.

What This Means for Joomla Site Owners

For site owners running Joomla 5.x or 6.0, the 6.1 stable release represented a straightforward minor upgrade — no major platform rewrites, no forced migration, just new features and improvements on top of the existing 6.x foundation.

The smart move for anyone still on an older version is to check whether the plugins and templates they rely on have published Joomla 6.1 compatibility notes before upgrading.

FAQ

Was Joomla 6.1 RC3 safe to install on a live site?
No. RC3 was a testing-only build. Production sites should run the stable release (April 14, 2026) or later.

What changed between RC2 and RC3?
The only change in RC3 was dispatcher support added to the jooa11y accessibility plugin, contributed by Harald Leithner.

What is a language freeze?
A language freeze means no pull requests touching language files are merged unless they fix a critical bug — it locks translations ahead of stable release.

Where can I test Joomla 6.1 without installing it locally?
Use the free hosted test sites at launch.joomla.org, which require no server configuration.

Is Joomla 6.1 a major or minor upgrade from 6.0?
It's a minor upgrade — no major platform rewrites or forced migration, just new features and improvements on the existing 6.x foundation.

Where should I report bugs found in a Joomla release candidate?
File issues at issues.joomla.org so they can be addressed before the stable release ships.
