Craft CMS vs Sulu: at a glance
What is Craft CMS?
Craft 6's alphas keep converting the plugin API, one removal at a time
Craft is running two lines with very different energy. The 5.10 maintenance branch ships one-bug releases hours apart and nothing else. Craft 6 is in its seventeenth alpha, still migrating onto Laravel: alpha 17 removes Plugin::settingsHtml() in favour of a settingsForm() built on the Control Panel Form system, replaces the Pane.vue component with a craft-pane web component, and moves another management command onto Laravel's schema API.
What is Sulu?
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.

Craft 6's alphas keep converting the plugin API, one removal at a time
◆ Current state
Craft is running two lines with very different energy. The 5.10 maintenance branch ships one-bug releases hours apart and nothing else. Craft 6 is in its seventeenth alpha, still migrating onto Laravel: alpha 17 removes Plugin::settingsHtml() in favour of a settingsForm() built on the Control Panel Form system, replaces the Pane.vue component with a craft-pane web component, and moves another management command onto Laravel's schema API.
◆ Where it's heading
The pattern established at alpha 14 has not changed shape, only advanced: every alpha retires another Yii-era extension point and re-lands it on the new stack, with craftcms/yii2-adapter carrying the compatibility burden. Alpha 17 adds an Inertia-native slideout system that renders any CpScreenResponse as an in-page panel, which is the control panel moving from a legacy JavaScript layer to a genuinely Inertia/Vue one rather than wrapping it. The long fix list — stale permission trees, autosave firing on unchanged values, provisional drafts created on page open, queue jobs stuck reserved — reads as the cost of that churn being paid down alpha by alpha.
◆ Prediction
Expect further alphas that remove specific Yii-era plugin APIs with adapter fallbacks, and the 5.10 line to keep shipping single-fix patches until a Craft 6 beta absorbs the team's attention.
Sulu
5.0MKT AUTO
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
◆ Current state
Sulu is a Symfony-based CMS for developer-built sites, and its release process is a synchronised pair: every 3.0.x patch ships within a minute of the matching 2.6.x patch, carrying largely the same pull requests. Six releases in five months — 3.0.8/2.6.25, 3.0.7/2.6.24, 3.0.6/2.6.23 — are almost entirely fixes, editor upgrades and framework compatibility work. A security advisory was patched across both branches in March.
◆ Where it's heading
Three threads run through the pairs. Editor upkeep is constant, with CKEditor moving to 47 LTS and then 48 and the fallout — table widgets, webpack font builds — fixed release by release. Framework compatibility is the second: Request->get calls replaced for Symfony 8, PHPUnit 13 and PHPStan kept green on lowest dependencies. The third and most interesting is data-model cleanup on the 3.0 side, where tags migrated from names to IDs behind a newly added DoctrineMigrationsBundle, with smart-content filters reworked to match. What is not visible is any capability that exists on 3.0 and not on 2.6 — a major version that is not yet behaving like one.
◆ Prediction
Expect the paired-release rhythm to continue with more Symfony 8 preparation and CKEditor 48 fallout. The open question is when 3.0 starts receiving work that is not upmerged from 2.6; until then the major version number is not buying users anything.
