v0.21.0

PolyUI v0.21.0

What's new

• Chromium viewport (experimental). A real embedded browser in the agent viewport — input forwarding, address-bar sync, in-place reloads. Off by default: Settings → Advanced → Experimental Chromium browser.
• Native Anthropic and Gemini providers. No proxy, no shim, both ings.
• Real keyboard shortcuts, driven from a single registry.

Major changes

• CEF runtime now ships inside the Linux packages and is staged correS bundles.
• Markdown renders while a response streams instead of after it finishes.
• Composer state is scoped per conversation, so drafts no longer leak
• Accessibility pass: audible toasts, visible focus rings, reduced motion actually honoured, auth gate rebuilt on Radix Dialog.
• PolyAgent removed.
• Release and nightly CI collapsed into one reusable build workflow.

Minor changes

• Titlebar branding and a reworked sidebar rail.
• Sidebar performance: unvirtualized list, tooltips mounted only when collapsed, resize observers settled instead of firing every frame.
• Unified scrollbars, icon and type scales across the app.
• Scroll-to-bottom button above the composer.
• Settings dialog is capped instead of filling the viewport.
• 13 of 15 Dependabot advisories patched.

Bug fixes

• CEF failing to initialise, plus an idle spin that pinned ~80% CPU.
• Workspace collapsing under the browser drawer; layout now shrinks correctly in small windows.
• Sending a message did not scroll to the bottom from further up the
• Sidebar collapse jumped on the first frame; animations looped at transition speed under reduced motion.
• Tooltips overlapping the title bar; conversation row hover bleeding
• Windows builds failing to link — CEF, whisper and ONNX now share one static CRT.
