MailBeez moves its addon catalogue onto V5 with the MAIA assistant, then grinds out 4.9.99 patches.
MailBeez is an email-marketing plugin for Zen Cart and similar shops, finishing a V5 platform rewrite. In late September most addons (review reminders, winback, abandoned cart, dunning) shipped V5 support and the MAIA assistant. October brought a prospects manager, customer insight and sender profiles in 4.9.99.11, followed by a run of small UI, analytics and maintenance patches.
Submagic is expanding from a captions editor into a full create-to-publish-to-analyze creator OS.
Submagic has rapidly outgrown its origins as a caption and auto-edit tool. In the last few months it added content ideation (Find Ideas), an MCP server that lets an AI agent drive the whole pipeline, native multi-platform publishing to six networks, and an analytics dashboard. The core editing features (captions, B-Rolls, auto-edit, intros/outros) keep improving in parallel. The product now spans the full short-form workflow: find an idea, script it, edit it, publish it, measure it.

October brought a prospects manager, customer insight and sender profiles in 4.9.99.11, followed by a run of small UI, analytics and maintenance patches.
The V5 rewrite is in its stabilization phase: features have mostly landed and point releases now fix compatibility and performance. The next milestone is a 5.0 core release, which the 4.9.99 numbering suggests is close.
A V5.0 core release is the likely next major step; the entries do not give a date.

Submagic is assembling an end-to-end creator operating system rather than a point editing tool. The recent additions each open a new stage of the workflow, ideation upstream, distribution and analytics downstream, and an agent interface that can orchestrate all of it from a single prompt. The direction is clearly toward owning the entire create-and-grow loop and reducing the creator's need to leave Submagic for any step.
Expect deeper analytics, with per-platform performance feeding back into Find Ideas' recommendations, and broader agentic control via the MCP server. A tighter loop where measured results directly inform the next script is the logical next move, given Find Ideas already explains 'why each video worked.'
