iTerm2 3.2.1

What's new in this version:

Mojave-specific Changes:
- The GPU renderer supports transparent windows
- The GPU renderer is no longer disabled temporarily while other views (such as the find bar) are visible
- Your theme will be changed to "Automatic" and will follow the system's light/dark theme. You can change it back to Light or Dark if you prefer

Bug Fixes:
- Fixes a number of crashes
- Fixes cases hotkey windows would be overlapped by the menu
- Improves rendering of box drawing characters on non-retina displays with GPU renderer
- Fixes a bug where a modal dialog could be overlapped by a floating hotkey window
- Reduced CPU usage when blinking text exists but blinking is disabled and the GPU renderer is on
- Fix appearance of copy mode cursor with GPU renderer
- Fix a problem where tmux window panes might not always have per-pane title bars when they ought to
- Fix a bug where terminal side margins could not exceed 100 points
- Fixes a bug where the frame right could be double what it ought to be during scrolling
- Fixes cases where non-hotkey windows would be raised above other apps' windows when activating the hotkey window
- Fix a performance issue when using fast user switching and a hotkey window is registered
- Fix a bug where announcements' frames could be wrong
- Do not use virtual keycodes to detect digits because it causes problems with certain keyboards
- Fix a bug where the split pane panel did not resize properly
- Improve menu detection so non-native full screen windows can adjust their vertical position properly
- Escape the user name for compatibility with active directory usernames that have a backslash
- Fix a bug where mouse reporting of the scroll wheel would sometimes reverse direction for one line when scrolling ends
- Fix a bug where hotkey windows would sometimes hide when a modal alert was presented. Many modal alerts are now window-modal rather than app-modal
- Fix a crash when dragging a color well
- Fix a bug where the wrong text could be used when you right click on an existing selection, the text under that selection changes, and then you pick an action from the menu

New Features:
- Add support for macOS 10.14
- Add support for CSI CHT control sequence
- New advanced pref to set the prominence of the outline on the selected tab when there is a colored tab present
- New advanced pref to adjust the prominence of text in non-selected tabs when a colored tab is present
- New advanced pref to adjust the prominence the outline of the current tab when colored tabs are present
- New advanced preference to set fallback value of LC_CTYPE when LANG can't be set because it would be an unrecognized locale

Other Improvements:
- When focus reporting is set or unset, the announcement asking if you want to turn it off is removed
- Improved performance for memory-starved GPUs with GPU renderer
- Performance improvents when there is a badge and GPU renderer is on
- Show "key" cursor icon at password prompt when GPU renderer is on
- Confirm before running a script that iTerm2 handles (e.g., by double clicking a .sh file)
- Improve vertical alignment of new-output indicator in tabs
- Improve contrast of tab titles in non-selected tabs when a colored tab is present
- Ignore trailing ] on URLs for semantic history
- Minimum Contrast no longer applies to box- and block-drawing characters
- Improve how advanced preferences are implemented for better performance
- Releases are now notarized for offline initial launch on macOS Mojave
- Performance improvements for long scrollback history
- Move "use bright colors for bold text" to Colors pane to make its true purpose clear: it actually has always controlled whether the bold color you specify gets used

Things Made Worse:
- Support for Growl has been removed because it cannot be notarized under macOS Mojave
