Changelog

Added

• Add an animated backdrop to the chat: the openheim atom drawn as a point cloud, shown smaller above the prompt in an empty chat and faded out behind the message column once a conversation starts. Respects reduced motion and pauses while the window is hidden

Changed

• Tool cards show the call's main argument next to the tool name, and list the input as labelled fields instead of raw JSON, with edit_file changes coloured as removed/added text
• Restyle permission prompts to fit inside the tool card, with colour-coded Allow / Always allow / Reject / Always reject buttons
• Sort sidebar sessions by last activity, so a resumed session moves to the top as soon as a message is sent
• A new session only appears in the sidebar after its first message, and an unused one is dropped when you switch away
• Move the app version from Settings → General to the bottom of the sidebar
• Update the built-in provider model lists to current releases. New defaults: Anthropic claude-opus-5-5, OpenAI gpt-6.1-sol, Ollama qwen3.8, Z.ai glm-5.3, DeepSeek deepseek-flash (replaces deepseek-chat and deepseek-reasoner, which DeepSeek retired in July 2026). Existing configs keep their models

Removed

• Release notes text in the update dialog

Fixed

• A sidebar session row now shows either the "generating" dot or the delete button, never both; the delete button is hidden while a turn is running

Added

• Include native debug symbols in Android release bundles, so crash reports in Google Play show function names

Changed

• Bundle the Inter and JetBrains Mono fonts with the app instead of loading them from Google Fonts, so the app no longer contacts Google on launch; code blocks now use JetBrains Mono as intended

Added

• Add full custom provider setup: API type, base URL and model list
• Add the provider "context window" setting (Settings → Providers → Advanced): set to the model's context window so long sessions drop the oldest turns before a request is sent, instead of after the provider rejects it as too long
• Say when a turn stops early (output token limit, refusal, iteration limit)

Changed

• Bump embedded openheim core to 0.15.0
• Stop shell commands the agent started (dev servers, watchers) when the app quits, on macOS and Linux
• MCP tool calls now time out after 10 minutes, and an MCP server whose connection closed is reconnected on the next call
• Make the left sidebar fully hidden when collapsed
• Bigger chat header, icon and send buttons, and a mobile-friendly artifacts view
• Default Gemini model is now gemini-3.8-flash (gemini-2.0-flash has been shut down)

Fixed

• Fix Gemini rejecting every request when an MCP server's tools were enabled
• Fix an OpenAI session failing on every prompt after an empty reply
• Show permission requests from delegate_task subagents, which had no tool card to appear on and left the turn waiting
• Keep thinking, text and tool calls in their original order when reopening a session

Changed

• Bump embedded openheim core to 0.12.0
• Upgrade frontend and Rust dependencies

Fixed

• Fix sessions/models/skills sometimes not loading on launch if the embedded connection was still starting up (e.g. slow MCP server connections)
• Fix Android crash when saving a config with a url-based MCP server
• Fix MCP connection error messages being cut off in Settings instead of showing the full text

Changed

• Improved remote connection handling and interface
• Update greeting message

Fixed

Added

Changed

• Bump embedded openheim core to 0.11.1 (from 0.9.0, via 0.10.0)
• Update greeting message
• Auto-close the sidebar on mobile after selecting a session
• Bigger, easier-to-tap "new session" button
• Sidebar and connections improvements
• Various UI improvements (chat view, settings tabs)

Fixed

• Fix Windows shell commands briefly flashing a console window
• Fix remote session skills not loading into the prompt box
• Fix iOS device build issues (script sandboxing, local network permission) and input zoom
• Fix local network permission copy shown to users in production builds
• Fix mobile app icons
• Fix settings tab active border

Added

• Show context usage in the prompt box

Changed

Added
