Sulu
Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.
A side-by-side editorial comparison of Kit (formerly ConvertKit) and Pimcore — release velocity, themes, recent moves, and the top alternatives to consider.
Kit rebuilt its landing page editor, then handed the controls to an AI agent.
Kit's recent releases converge on one thing: giving creators a full publishing surface inside Kit rather than sending them to a third-party page builder. The landing page editor was rebuilt in June with 20+ templates and full control over layout, fonts and sections; custom favicons and the Creator profile to Newsletter site rename finished the job of making those pages feel owned rather than hosted. The newest release lets the Kit MCP build and edit those pages directly. Alongside runs an audience-intelligence thread - Subscriber Signals in early access - and network features letting creators request connections with each other.
Nearly every release in this window carries security hardening — Pimcore is working through an injection sweep.
Pimcore maintains two calendar-versioned lines in parallel, 2026.2.x and 2026.1.x, with fixes landing on the newer line and selectively backported. The content is dominated by input-validation work: explicit field allowlists on Custom Report updates, an ORDER BY column allowlist for redirect listings, rejection of unwhitelisted filter properties, escaped field names in DataObject JOIN conditions, hardened unserialize paths, and CSV exports bound to the requesting user. Feature work is thin by comparison — a CDN integration and a TemplateProviderInterface extension point in 2026.2.1.

The Kit MCP is the axis. It arrived in May as a read-and-analyze tool - ask questions about your list, create tags or broadcasts from Claude, ChatGPT or Cursor - and has now crossed into building the actual published artifact. That sequencing is deliberate: rebuild the editor as a structured, template-driven system first, then expose it to an agent, because an agent can only assemble a page that is composed of describable parts. The rename and favicon work point the same way, toward Kit as the place a creator's web presence lives rather than just where email is sent.
Expect the MCP surface to extend from landing pages into sequences and the newsletter site itself, and Subscriber Signals to move out of early access as the data layer the agent reasons over.

The pattern is a systematic pass over places where user input reaches SQL or deserialization, spread across releases rather than bundled into one advisory — Custom Reports alone are touched in three separate releases. Alongside it runs a slower cleanup of the v11 era: admin functions removed, admin translations deprecated, v11-specific workflows refactored to v12. A task in the most recent release adds backward-compatibility break detection to the project's own code review tooling, which reads as an attempt to keep that cleanup from breaking integrators unannounced.
Expect the hardening sweep to keep producing small paired releases on both lines, with Custom Reports and listing filters the likely remaining targets, and further admin-layer removals as the v12 cleanup continues.
