 ## Unreleased
 
-### Desktop
-
-- **The app icon is the CoDev mark** — the Dock, taskbar and installer icons
-  were still upstream's black "o" square (and the blueprint variants for the
-  dev/beta channels). They are now the brand-red "C" — the same glyph the
-  `codev --mini` splash badges with — on a white tile, generated for every size,
-  `.icns` and `.ico` from a single source of record
-  (`packages/desktop/icons/icon.svg`) by `bun ./scripts/generate-icons.ts`. The
-  macOS `.icns` and the Dock PNG use Apple's Big Sur grid (inset plus drop
-  shadow) so the icon sits correctly next to native apps; all three channels
-  ship the same mark for now.
-
-- **The desktop app says CoDev Code, not opencode** — every user-visible string
-  the app still rendered as "OpenCode" is rebranded: the window title, the crash
-  and unresponsive dialogs, the updater and CLI-installed messages, the settings
-  descriptions, the update toasts, the WSL onboarding steps, the server-switcher
-  dialog, and the app name — in both English and Spanish, with the CLI-command
-  hint now naming `codev`. (The hosted "OpenCode Zen" / "OpenCode Go" model
-  services keep their real names, since the app still connects to them.)
-  Internally, the WSL CLI-management code and the desktop↔web wire values were
-  renamed to codev as well.
-
-- **Debug-log export actually collects the CLI's logs** — "Export logs" read from
-  a stale `opencode` directory while the CLI writes its logs under `codev`, so the
-  server logs were silently missing from the exported archive. Fixed.
-
-### Desktop / Web UI
-
-- **No wordmark on the new-session screen, and the composer is centred** — the
-  screen led with a large watermark of the product wordmark and anchored the prompt
-  box a quarter of the way down the pane to make room for it. The watermark is gone
-  and the prompt box now sits in the middle of the pane.
-
-- **The banner wordmark reads "codev"** — the large wordmark on the home screen,
-  the error page and shared-session pages still spelled "opencode". It is now the
-  lowercase codev wordmark, drawn from the same pixel glyphs as the TUI banner and
-  the landing page: "co" in the brand navy on light themes and the theme foreground
-  on dark, "dev" always in the brand red, with no drop shadow. The new-session
-  watermark was rebranded the same way before being dropped, so it comes back
-  branded if it is ever reinstated.
