Pencil2D vs Storybook: at a glance
What is Pencil2D?
Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
What is Storybook?
Storybook is turning its component workshop into a tool surface agents can call.
The 10.6.0 alpha train is running two workstreams at once. One is Angular: replacing Compodoc with an in-process docgen analyzer, gated behind a flag, with story-docs snippets generated from it. The other is Skills - a series of milestone PRs building toolsets, MCP wiring, and now public storybook skills and storybook tools commands. Routine framework upkeep fills the rest: TypeScript 6, TanStack fixes, Next.js and Vite plumbing.

Pencil2D's 0.7.1 candidates are mostly about not losing the user's work
◆ Current state
Two release candidates for 0.7.1, twenty months apart, plus the earlier 0.7.0 candidate. The substantive changes are data-integrity fixes — a ClipboardManager memory leak, frame data loss when copying bitmap keyframes, project recovery dialog improvements, backups on polyline completion — alongside macOS codesigning and notarization and a reworked toolbox layout that reflows into rows or a single column.
◆ Where it's heading
For a hand-drawn animation tool the recurring subject is protecting in-progress work, and that is where these candidates spend their effort. The platform work sits alongside it: signed and notarized macOS builds and an updated Qt6 runner are the cost of shipping a desktop app users can install without warnings.
◆ Prediction
A general 0.7.1 release is the natural next step once the candidate cycle settles, though the twenty-month gap between candidates makes timing hard to call.
Storybook

Storybook is turning its component workshop into a tool surface agents can call.
◆ Current state
The 10.6.0 alpha train is running two workstreams at once. One is Angular: replacing Compodoc with an in-process docgen analyzer, gated behind a flag, with story-docs snippets generated from it. The other is Skills - a series of milestone PRs building toolsets, MCP wiring, and now public storybook skills and storybook tools commands. Routine framework upkeep fills the rest: TypeScript 6, TanStack fixes, Next.js and Vite plumbing.
◆ Where it's heading
The Skills milestones have been landing in order - defineToolset and the manifest component API in alpha.4, the core toolsets reworked in alpha.6, then addon-mcp and @storybook/mcp moved onto those shared toolsets, then the CLI commands derived from them at runtime. That sequence turns Storybook from a place where a developer looks at components into a service an agent can query for them. Alongside it, the Angular docgen rewrite removes a long-standing external dependency, and the experimental Playwright CT integration was dropped - the train is consolidating as much as it is adding.
◆ Prediction
With toolsets shared across the MCP packages and both CLI commands public, the remaining Skills milestones should surface documentation and defaults - which toolsets ship enabled, and how an agent discovers them - before 10.6.0 leaves alpha.
