Features

• Added new default Adwaita and Adwaita Dark color schemes
• You can now customize the working directory for new tabs. It can be set to persist the last tab's directory, the user's home directory, or an arbitrary location
• Closing a tab or a window that still has a running process will now prompt you for confirmation
• Black Box now uses the default Adwaita tab style. As consequence, some header bar options, including "Show Borders" have been removed from the preferences window
• Added the option to disable terminal bell
• Added option to use bright colors for bold text
• You can now get a desktop notification when a process completes on an unfocussed tab
• Context-aware header bar: the header bar can now have special colors when the active tab is running sudo or ssh
• Added open and copy link options to the right-click menu
• You can now rename tabs with the new tab right-click menu, or with a new shortcut Shift + Control + R
• Added a quick application style switcher to the window menu

Improvements

• Some configuration options have been grouped together in the preferences window
• Application title is now bold when there's a single tab open
• Performance and bundle size optimizations

Bug fixes

• Fixed an issue that caused terminals not to be destroyed when their tabs were closed
• Improved keybinding validation, allowing more valid key combinations to be used
• The window title is now centered when there's only one tab
• Sixel is now disabled for VTE builds that don't support it. This primarily affects non-Flatpak users, as all Flatpak builds ship VTE with Sixel support
• Fixed an issue that caused windows launched with custom commands to not have a title
• Black Box will now show an error banner if spawning a shell or custom command failed and will no longer close immediately
