Lingua v0.6.0

• Signal-Slate redesign: A workspace-wide redesign pass that lands the new notebook surface, tightens the editor chrome, and folds in broad platform hardening across the renderer. The visual language carries forward from Signal-Slate v2 while the workspace layout, panels, and notebook entry points are rebuilt around it.
• Notebook workspace: A literate, multi-cell notebook surface — ordered code and prose cells in one document — with one-step import of existing Jupyter .ipynb notebooks into native Lingua notebooks.
• SQL and HTTP workspaces: A dedicated SQL workspace for ad-hoc querying and a full HTTP workspace for composing, sending, and inspecting requests, including import of Postman and Bruno collections.
• Recipe practice library: A built-in library of runnable recipes for guided practice, with a run panel wired into the editor.

• Scratchpad excellence: A full nine-slice closeout for the JS / TS / Python Scratchpad workflow. Per-tab Run / Debug / Scratchpad mode toggle with the Run mode disabling auto-run for compiled languages. Smart auto-run completion gate so the runner waits for a coherent edit before firing. Pinned // @watch <expr> and # @watch <expr> annotations that survive across runs. Per-tab recent-runs replay with one-click rerun (Mod+Shift+H) and a Pro-gated <RecentRunsPill> in the result header (Free tier sees an upsell variant). Opt-in bare-expression auto-log mode for JS / TS with per-language Settings defaults and per-tab overrides. Pre-set stdin buffer with a dedicated bottom-panel Input tab consumed by prompt() / readline() (JS / TS) and input() (Python), with a "Used N of M lines" pill after the run. Per-language execution timeout presets (quick / normal / long / extended) with optional live mm:ss countdown pill and a // @timeout 60s magic-comment override. Compare-with-last-stable-run toggle in the result header with a multi-snapshot ring, pin/freeze support, three diff granularities (line / word / character), and inline + / − / ~ diff badges. Post-execute variable inspector panel mutually exclusive with Compare, surfacing typed previews for primitives, objects, arrays, Maps, Sets, errors, dates, and functions with Mod+Shift+I toggle, optional recursive expansion, and a case-insensitive name filter.
• Explicit JS / TS runtime modes: Per-tab runtime selector with three implemented modes. Worker (default) keeps the existing fast Web-Worker scratchpad path. Browser Preview ships an iframe-sandboxed runtime with srcdoc CSP, runId-anchored postMessage bridge, parent-owned timeout, scoped multi-file preview seed, and an inspect-in-window button — useful for HTML / DOM / canvas demos. Desktop Node spawns a real node child process with a parent-owned SIGTERM→SIGKILL timeout, a NODE_TOOLCHAIN_KEYS env allowlist, automatic node_modules/ cwd resolution, package.json#type === 'module' detection, and a first-run trust notice before the first execution touches your filesystem and network.
• Signal-Slate v2 chrome: New 36px header row above the toolbar with app mark, filename + unsaved dot, license badge, command-palette search, and settings gear. Toolbar trimmed of the seven right-side icons that duplicated the new header. Variables panel can now dock to a Variables tab in the bottom panel (Settings → Editor → Variable inspector surface) instead of the floating card. Toolbar chips (Lang / Runtime / Workflow) stay clickable even without an open tab and auto-create the right tab on demand so the toolbar can never deadlock the user out of a fresh session.
• Rich-output foundation + //=> table directive: New RichOutputPayload type discriminator (superset of ScopeValue) covering map / set / date / promise / table / rawText payloads, with image and chart stubs reserved for the next slice. JS / TS runners attach a typed RichOutputTable payload when the user annotates an expression with //=> table — the inline pill upgrades from a JSON blob to a compact Table(N×M) — cols summary. Python's #=> table is recognised by the parser even though the Pyodide runner does not emit the payload yet. Foundation for the upcoming console-panel widget, popover surface, and chart / image / sandboxed-HTML rendering.

• Rich language intelligence for Python, Rust, and Go: Inline diagnostics, completions, hover documentation, and parameter hints. Rust uses rust-analyzer and Go uses gopls when installed locally; Python runs in-process. Web build keeps these languages in validate-only mode.
• JS/TS debugger (preview): Click-to-toggle gutter breakpoints with Mod+Shift+B, a Debugger drawer with step controls, Settings entries to disable or clear all breakpoints, and TypeScript source-map composition so breakpoints stop at the line you authored.
• Developer utilities productivity layer: Cmd/Ctrl+K launcher with fuzzy search, Cmd+Shift+C / Cmd+Alt+R to copy or replace utility output, per-tool history with persistence, drag-reorder favorites with full keyboard support, clipboard-on-focus consent, and Apply-from-input across 29 panels.
• QR utility closeout: Drag-drop image decode, Copy-as-PNG, FG/BG color pickers with a WCAG-AA contrast guard, high-contrast preset, and SVG download.

• Web build stability: Lifted the Node heap limit for the web build job so release builds stop failing from memory pressure.

Read v0.2.3 notes →

• Public release hygiene: Added source-publication checklists, release security guidance, third-party notice reporting, and secret-scan configuration.
• Offline Python runtime validation: Vendored Pyodide runtime assets with integrity checks so packaged desktop builds can prove Python runs without a CDN fallback.
• Desktop release verification: Added production dependency audit, checksum verification, SBOM generation, and packaged macOS smoke coverage.
• Native execution trust boundary: Go and Rust execution now require explicit acknowledgement and use a filtered environment across detection and run paths.
