Added

• Added verified in-app Windows updates — Nebula can download the exact official Windows x64 installer in the background, show progress, validate its size, PE header, and SHA-256, then wait for explicit confirmation before launching setup. Fixed
• Fixed automatic update checks to use the real GitHub latest release and compare it with the running package version before showing a reminder; skipped versions and three-day reminders remain respected.
• Fixed update notifications disappearing before users could act; reminders now remain visible in the bottom-right corner, and completion or failure replaces the original notification with the appropriate next action.
• Fixed update and confirmation dialog geometry and typography to match the established width, vertical position, and font sizing, while overlay clicks, Escape, and cancel buttons consistently run the cancel action.
• Fixed terminal opacity returning to 82% after being set to 100% when legacy blur settings were normalized and reloaded.
• Fixed the keymap page leaving a large empty gap above its shortcut rows.
• Fixed the font group popup drifting away from its selector; hovering a truncated font family now reveals its complete name.
• Fixed the sidebar resize cursor and width calculation missing the visible divider, so dragging begins directly on the baseline instead of several pixels to its left.
• Fixed PowerShell current-directory reporting under the Windows home directory. The prompt may still display ~, but Files and Git integrations now receive the absolute path and correctly detect repositories below the home directory. Improved
• Improved the update flow with download progress, retry, verified, install, and failure states, plus a second installer verification immediately before launch.
• Improved modal consistency across workspace, pane, tab, file-tree, and settings confirmations without removing the new component's click-outside cancellation behavior.
