0.7.5

• Colours, type and scale. The chrome moves to a neutral dark palette with Studio orange for brand actions and an orange keyboard focus ring. Body text is 12 px with three text weights, corner radii are 6, 8, 12 and 16 px, and rows, fields and text grow only where the new scale says. Regions and panel widths stay where they were.
• Controls. Buttons, fields, checkboxes, toggles, tabs, menu items, badges, tooltips and the rest paint from one shared look. A keyboard-focused control draws a 2 px focus ring in every state, menu items sit inset in their panel, and a switch shorter than 24 px takes clicks in a 24 px band.
• Window and left panel. The title bar, file tabs, left rail, floating toolbar, rulers and shell menus use the new look, with a 4 px press band beside each ruler. Pages, the Dev section and Layers keep their 240 px width and section order with 32 px rows and buttons, Studio orange marks live state, and a click on a page row leaves the keyboard on the canvas.
• Popovers, dialogs and the command bar. Command bar rows are 36 px, Enter runs the row you picked with the keyboard, and in a small window the bar scrolls its rows instead of covering the bottom toolbar. Dialogs use 14 px text and 40 px buttons, and brand buttons carry a dark label on orange.
• Home. Home uses the same dark palette, + Design file is Studio orange with a dark label instead of blue, and the sidebar, header, filter bar, file grid and Trash stay where they were.
• Assets, Variables, Libraries and Check designs. The Assets search field shows a focus ring only while it has focus, Variables cells draw nothing at rest and booleans are switches, Libraries shows change labels such as New and Changed as status chips, and Check designs rules use checkboxes with a segmented contrast choice.

0.7.0

• Styles. Delete a style (Delete style) while linked layers keep its resolved values and variable bindings, group styles by / prefix into renameable folders (Rename folder) in Figma's order, edit style descriptions (Description) and read them as hover tooltips in style pickers and the colour picker's Libraries tab, and keep text alignment on each text layer while text styles carry paragraph indent, list spacing and leading trim.
• Effects and shadows. Drop shadows and inner shadows take a blend mode (Blend), the shadow cut-out of a frame with no fill and Show behind off follows its visible children's shapes, and the Effects section's + menu caps each effect type (8 drop shadows, 8 inner shadows, 1 layer blur, 1 background blur) without trimming imported effects.
• Export and files. PNG and SVG export bounds match Figma for shadows, strokes and groups; after an export, a toast shows where the file went with Show in folder (using Downloads when no save dialog is available) and never overwrites an existing file (Card-1.png, Card-2.png, …); and atomic saves keep macOS ACLs and extended attributes while leaving your own .tmp files alone.
• Left rail and panels. The left rail is icon-only with hover and keyboard-focus tooltips (Main menu, File, Agents, Assets, Tools, Variables, Plugins, Updates & Shortcuts), and a draggable separator between Pages and Layers resizes the Pages list and remembers its height.
• Agents panel and canvas. Expanding the changed layers card with Show all scrolls inside the Agents panel with Show less while keeping Revert and Keep reachable, and an interrupted move on the canvas keeps the last pointer position.
• CLI and MCP. A --screenshot run with unsaved edits closes after writing the PNG without stopping on Save changes to {name}?, and --apply-spec, designos_apply_spec and designos_apply_batch centre hugging button labels inside NodeSpec presets and aligned frames while designos_create_node and designos_update_node keep explicit text box sizes.

0.6.5

• Starter file. A new library gets a Getting started project with DESIGN-OS Studio Starter, and an existing library gets it once on its first launch of 0.6.5; files you already have are not touched. Open starter sample opens a fresh copy, launching with no file argument opens Home, and the older samples, --seed-library, release --fixture and the old examples folder are removed.
• Variables. designos FILE --export-variables OUT.json --format dtcg --mode MODE exports one variable mode across the file’s collections (or --collection) as a single self-contained DTCG .tokens.json file with default-mode fallback, --resolve-aliases, and --color-format (hex or object), and multi-file DTCG exports keep same-named collections distinct.
• Agents panel. Tabs clear their scrollback when an agent redraws on a UI zoom so output no longer repeats, quiet Codex turns change from Working… to Done after 1.5 s and hide Stop, and the approval banner shows Show prompt to focus the current waiting tab or Open tab to switch to another waiting tab.
• Canvas and .fig import. Frame, component and instance labels repaint after an agent rename and cut to fit with … like Figma; hug and fixed-width NodeSpec text is measured with the text renderer; .fig files with top-bit 64-bit values import and export cleanly; and icons and vectors inside resized component instances scale with the instance while keeping their strokes.
• Styles and performance. Deleted and orphan style records from imported .fig files are hidden from style pickers, Assets, layer chips and MCP listings, while unnamed listed styles show Unnamed fill style, Unnamed text style, Unnamed effect style or Unnamed grid style; large multi-layer edits finish faster by recording only the layers that changed.
• CLI and MCP. --select accepts id:<n>, fig:<figma id>, name:<text>, none or a layer name, supports --zoom fit, and exits 2 without writing on a miss; Home › Import › Enter a path… opens ~/ and file:// paths and starts toast timers on first paint; MCP imports enforce a 512 MiB FILE_TOO_LARGE limit, and MCP file writes return INVALID_NAME and NAME_TOO_LONG.

0.6.3

• Agents panel. Hook outputs (agent-status.json, agent-events.jsonl, turn-marks.jsonl, claude-transcript.json) and Claude’s prompt-hook replies live in a Studio-private hook-out folder outside the session folder, $TMPDIR, /tmp, /var/tmp and every folder an agent CLI is granted, and the turn-mark hook reads doc-patch.jsonl size with stat -L instead of opening it.
• CLI and MCP. --screenshot on a missing, empty or corrupt file exits 1 with an error message and writes no PNG. --apply-spec, designos_apply_spec and designos_apply_batch report invalid NodeSpec fields in plain words instead of serde type errors, and the docs note that Ask covers agent tabs started from Studio while your own designos CLI and external designos-mcp hosts approve their own calls.
• Linux. Home › Import opens the file chooser when org.freedesktop.portal.Desktop starts on first use or when zenity is installed, and when no file dialog can open it names the cause and offers Enter a path….

0.6.2

• Agents panel. Ask-mode approvals, Claude’s hooks and MCP config, and session folders for unsaved files live in Studio’s own data folder, and Studio and designos-mcp refuse links and FIFOs in session files. The skill and agent files no longer include the document or page name.
• Gemini, Grok and Antigravity. Gemini CLI tabs in Ask mode show Needs approval with an Open tab button and hold the composer while Gemini’s confirmation prompt is on screen. Ask-mode Grok and Antigravity tabs move non-Studio session configs aside before starting, and Grok never evaluates a .envrc.
• Styles and Properties. Create a text style from a text layer in the Typography section (Create text style), pick styles from enabled libraries when the file has none of its own, and export a page from the page panel’s Export section.
• Components and Dev Mode. Syncing a main component keeps its instances’ own layer names. Dev Mode keeps each code line on one row with horizontal scrolling, grows the MCP prompt box to fit, and escapes \, ", \( and control characters in SwiftUI strings.
• Command palette. Rename layers semantically and Boost resolution take about a second per click on a very large page, where they took about four.
• CLI and MCP. designos-diff --version prints the version. MCP file writes (designos_save_file, designos_render_png, designos_export_fig_file) refuse links, control or bidi characters, and names over 255 bytes; designos_export_fig_file refuses an existing file unless overwrite is set; and outside-workspace errors no longer echo the path.

0.6.1

• Agents panel. The bottom terminal dock and the >_ rail button are gone. Cmd+` (Ctrl+` on Windows and Linux) opens and closes the Agents panel. Agents ask before acting by default.
• Unsaved edits. Studio asks Save changes to {name}? before a close, a quit or an open drops edits to a file outside the library, and asks before a file changed on disk replaces them. On macOS, Cmd+Q asks too. An agent that opens another document no longer replaces yours.
• Undo. Undo and redo of your own edits restore the document exactly. The command palette’s design fix and its Figma AI rows are one undo step each. After a font face arrives, and for an agent’s edits, undo solves layout again.
• Paste and drop. Paste text and images from other apps, and drop PNG, JPEG or WebP files on the canvas. Pasting a main component in its own file makes an instance.
• .fig files. Export never replaces an existing file and says where it wrote. designos --export-fig refuses a path that does not end in .fig and a symbolic link, and needs --overwrite to replace a file. A save or export to .fig or .pen warns when it leaves comments out.
• Slow machines. Draw, move, resize and rotate end where the pointer let go. A software renderer starts on the CPU canvas.
• CLI. designos --version prints the version, and a file argument that is not on disk stops with an error.

0.6.0

Screenshots retaken with the 0.7.5 release build, captured headlessly with designos-studio --screenshot (2x) on a copy of the Untitled UI PRO v8.0 Figma kit, by Untitled UI. Click an image for full size. The approval card comes from the built-in --panel agents-approval-queued preview.

Also in 0.6.0

• Agents panel. A file keeps its sessions after a restart. Review what an agent changed in a turn and keep it or revert it in one undo step. Stop one agent or all of them from the panel.
• Variables. Import and export Figma JSON and W3C Design Tokens (DTCG) from the Variables menu, or with --import-variables and --export-variables. An import merges into the file and reports what it skipped.
• MCP. Agents can see the design, read its design system, write in one step with designos_apply_batch and check their work with designos_lint.
• Dev Mode. HTML joins CSS, Tailwind, React, SwiftUI, UIKit, Compose and Android XML.
• License. Studio is source-available under PolyForm Shield 1.0.0. Releases up to 0.5.0 keep MIT or Apache-2.0.
