Tessera

Tessera v0.1.7

Tessera v0.1.7 is a Claude Code-heavy release: it adds Opus 4.8 and Ultracode support, lets chats participate in the same Todo / Doing / Review / Done workflow as tasks, brings recent conversations into the list view, improves the workspace file editor, and ships more reliable provider status handling.

Highlights

Claude Opus 4.8, Ultracode, and Custom Models

• Added Claude Opus 4.8 and claude-opus-4-8[1m] to the Claude Code model picker.
• Added Ultracode support for Claude Code by passing the correct ultracode setting instead of treating it as a normal effort value.
• Added a custom model field for Claude Code, so users can enter any model ID accepted by their installed Claude CLI before Tessera ships an updated curated model list.
• Persisted Claude Code model and effort selections per session, including Opus 4.8 / Ultracode choices across restarts, resumes, and retries.
• Thanks to @jakedev796 for the original Opus 4.8 and custom model override contribution in https://github.com/horang-labs/tessera/pull/78. This release restores and extends that work with Ultracode handling, persistence, and test coverage.

Claude Code Fast Mode

• Claude Code sessions can now use Fast Mode from Tessera.
• Fast Mode can be toggled from the composer controls or via /fast.
• Fast Mode is persisted with the session and is sent through Tessera's Claude Code spawn/resume path.

Claude Code Billing Notice

• Tessera runs Claude Code through the non-interactive claude --print / stream-json path.
• Anthropic states that starting June 15, 2026, Agent SDK and claude -p usage on subscription plans draws from a separate monthly Agent SDK credit, not the regular interactive Claude usage limit. For Korea/Asia time zones, this effectively starts on June 16.
• Tessera users authenticating Claude Code through a Claude subscription should expect Tessera Claude Code usage to count against that separate credit pool once the policy is active. See Anthropic's Claude Code Agent SDK docs: https://docs.anthropic.com/en/docs/claude-code/sdk

Provider Status Reliability

• Fixed transient provider auth/model probe failures being shown as needs_login.
• Claude Code, Codex, and OpenCode now keep true auth failures as login-required, while timeout/spawn/unknown probe failures are classified separately for better diagnostics.
• Welcome @sjh9714 as a first-time Tessera contributor for this fix in https://github.com/horang-labs/tessera/pull/77.

Chat Workflow Status

• Standalone chats can now be managed like work items.
• Chats can move through Todo, Doing, Review, and Done, instead of living only as plain conversation entries.
• Chat workflow status is reflected in the board, list/sidebar grouping, drag-and-drop behavior, and session persistence.

Recent Conversations in List View

• Added a Recent Work / recent conversations section to the list view.
• Recent conversations remain stable while sessions are running, so active work does not jump around unexpectedly.
• Sidebar and collection grouping were cleaned up so projects, collections, tasks, and chats are easier to scan.

File Editor and Workspace Improvements

• Added a Monaco-based workspace file editor/viewer.
• Added workspace file path actions and a file context menu for common file operations.
• Improved code block rendering, syntax highlighting, markdown preview behavior, and workspace file panel handling.
• Improved file and file-list session APIs so workspace file metadata is more consistently available across chat and workspace panels.

Board, Notifications, and Desktop Polish

• Improved kanban board/card/column interactions and live sync behavior.
• Fixed unread notification priority after replay so completed sessions with unread updates stay visually prominent.
• Fixed board popout live-sync regressions covered by contract tests.
• Fixed Electron draggable regions around All Projects and related desktop chrome areas.

Release Engineering

• Desktop release builds now cover Windows x64, macOS Intel, macOS Apple Silicon, and Linux x64.
• Windows builds isolate the runner user profile to avoid environment-specific build failures.
• macOS DMGs are signed, notarized, verified, and stapled during release builds.
• Linux builds verify both AppImage and deb artifacts, including an AppImage startup smoke test.
• Published @horang-labs/[email protected] to npm and marked it as latest.
