Astra
Two release trains, zero new features — Astra has been in pure maintenance mode since spring.
A side-by-side editorial comparison of HeroUI and Storybook — release velocity, themes, recent moves, and the top alternatives to consider.
HeroUI grew a component catalogue, then wired it into a chat editor.
The feed runs from March 2024 to July 2025 and stops there, so nothing here describes the last twelve months. Across that stretch the pattern is consistent: batches of components counted in the headline, a page reorganisation once the catalogue outgrew a flat list, framework currency with React 19 and Next.js 15 and later TailwindCSS v4, and a rebrand from NextUI Pro to HeroUI Pro in January 2025. The one change of kind is instant editing of any component inside HeroUI Chat.
The 10.6 alphas are an Angular tooling rebuild wearing a version number.
Storybook is five alphas into 10.6.0, shipping roughly weekly. The dominant thread is Angular: Compodoc parsing extracted into its own package, docgen moved to the server, on-demand Compodoc runs, required inputs derived from Compodoc's own flag, and alias-collision handling corrected. Alongside it, TanStack support keeps getting patched into shape and TypeScript 6.0.3 landed in the first alpha.

The archived arc moves from selling a catalogue to selling a workflow — a component is worth more if it can be customised where it is chosen rather than copied into an editor first. Framework support releases show the other constant: a paid component library lives or dies on how quickly it tracks the framework underneath it. What has happened since July 2025 is not visible from this source.
No recent entries support a confident prediction; the actionable finding is that this feed has been silent for roughly a year and needs re-pointing before HeroUI's direction can be read.

Two rebuilds are running in parallel. The Angular integration is being decomposed — parsing, docgen, and metadata pulled out of the framework adapter and into shared packages, with work moving off the client and onto the server. Separately, a component-metadata layer is forming in core (ComponentMetaManager, manifest component API fields, shared CSF story-shape helpers), which reads like groundwork for tooling that consumes Storybook's metadata rather than its UI. TanStack Start is being treated as a first-class router target rather than an edge case.
The Angular extraction looks close to done, so expect the remaining alphas to shift toward stabilizing the manifest and metadata APIs before a 10.6 beta.
