Sonarr
Sonarr's 5.0 builds move from UI rework to safer restores and keyboard-friendly selects.
A side-by-side editorial comparison of Payload CMS and Stacker — release velocity, themes, recent moves, and the top alternatives to consider.
Payload v4 enters beta: redesigned admin, TanStack Start support and agent instructions.
Payload 4.0 moved from canaries to beta on October 9, bundling an admin UI redesign, TanStack Start as a second framework alongside Next.js, hierarchies, tags, grid view, upload versioning and a rewritten MCP server. Two betas followed within a week; beta.2 moves the TanStack adapter to stable TanStack Start and renames LLM instructions to agent instructions. The canaries also flipped the Local API to enforce access control by default.
Stacker's AI agent has absorbed every part of app building except the data itself.
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.

Payload is loosening its Next.js dependency and building agent features into the CMS itself: editors can manage instructions that flow into the CLI and MCP schemas, and upgrades come with an agent-assisted codemod. The betas are now mostly fixes and documentation, which points toward a stable 4.0.
Expect weekly betas focused on migration fixes and docs, with more framework-adapter work for TanStack Start. The entries don't give a 4.0 stable date.

The sequencing is deliberate: each release hands the agent one more thing that previously required the no-code editor, while the company repeatedly reassures users that the full editor still works on AI-built apps. That dual framing — build by conversation, refine by hand — is the position Stacker is defending, and it is a reasonable answer to pure prompt-to-app tools that leave nothing to adjust afterwards. The portal release is the notable widening, since it points the agent at the external-user product rather than internal tools.
Every surface except data connection has now been handed to the agent; connecting and mapping an external source — the step still done manually before any of this works — is the remaining gap, and the spreadsheet uploader is the first move toward closing it.
