2026-08-19
Version: v0.1.0-rc.8[✓] LATEST
Multimodal workflows and installable subagents
Native image input reaches commands and references, while Claude Code and Codex become installable profile bundles.
Major updates

Native multimodal requests — DeepSeek model adapters can enable native image input; commands such as /goal and /plan accept mixed text and images.

Richer @ references — the composer menu can reference both workspace files and prior sessions.

Installable subagents — Claude Code and Codex providers can be installed on demand as Profile Bundles; Codex adds non-interactive permission modes and named instances.

Persistent PowerShell — Windows PTY terminals gain persistent PowerShell sessions, enabled by default in the Minimal preset.

Reliability and experience

Bound oversized and accumulated image payloads before they can break model requests.

Preserve visible response prefixes after cancelling generation, including follow-up prompts and forked sessions.

Improve custom OpenAI-compatible gateway support and reasoning-content passback.

Add concurrent web_search queries, prompt subagent result delivery, faster large-session forks, and automatic browser opening for local dsh web runs.

Upgrade note

SQLite persistence is smaller and faster, but this release changes its on-disk storage format. Back up important sessions before upgrading.

Version: v0.1.0-rc.7
Plugin-owned settings and visible subagent jobs
Plugins can own their settings surfaces, and Codex or Claude Code subagent work becomes visible in the Job Panel.
Major updates

Plugin-owned settings — plugins can register their own settings cards instead of depending on a fixed host form.

Subagents in the Job Panel — Codex and Claude Code tasks surface as trackable background jobs.

Durable image attachments — MCP and ACP persist image attachments, while PTC Mode forwards nested images.

Reliability

Fix persistent Bash latency in the Minimal preset and stack overflows while paginating large histories.

Keep sessions usable after max-token truncation and align the Safari composer cursor with its text.

Upgrade to node-pty 1.2 beta for broader terminal compatibility across platforms.

Experience improvements

Refine the Cordis dynamic plugin panel and preserve drafts inside collapsible question cards.

Add a low reasoning-effort option for DeepSeek models while keeping high as the default.

Rename the English Code mode preset to PTC mode.
