iTerm2 3.3.4

What's new in this version:

New Features:
- There's a new pref for whether you want to be asked to confirm quitting the app when there are no windows

Improvements:
- Infer current job name (for status bar, title bar, etc.) when using tmux integration locally
- Append to automatic log output files by default, instead of replacing them
- Search history is no longer opened by default when you type in a Find field. Press the down arrow to see your recent searches
- Control sequences that set the window or icon title now cause that title to become visible
- Preserve the exact dimensions of sixel images when possible
- Translate italic to reverse video in tmux integration
- The git status bar component now truncates long branch names instead of disappearing because it's too big to fit
- Python API scripts are now run through the user's shell so they'll have the right PATH, in case they want to spawn subprocesses
- Use dark appearance for scrollbars in minimal theme when the terminal background color is dark
- When you create a tab with the Python API, iTerm2 will no longer get activated automatically
- Add "disable status bar" to the status bar context menu

Bug fixes:
- Fixes a bug when clicking on an iTerm2 window with a selection while another app is active: the selected text is no longer copied to the pasteboard
- Fix many crashes
- Fix a bug where two custom status bar components or title providers could not run concurrently if their callbacks had the same signature
- Fix a regression where control-| stopped sending control-backslash on Japenese keyboards
- Fix flickering job name when using tmux integration locally
- Show a context menu when right clicking on the titlebar in minimal or compact mode when there is no tab bar
- Fix colors of graph-based status bar components in dark mode
- Fix a crash when a shell integration-reported hostname has a leading dot or two consecutive dots in its name
- Use the right color for the window shortcut number in minimal theme when the first tab is colored
- Fix various rendering bugs with inline images in both the GPU and legacy renderers
- Fix a bug where popping an icon or window title from the stack didn't always work
- Fix a bug that caused hotkey windows to immediately hide after showing when two of them had the same shortcut
- Fix GPU rendering of ASCII text when the font includes glyphs that spill outside their bounds to the left, like AnonymousPro
- When stealing key focus is enabled, make the session that's receiving stolen keys first responder
- Fix a bug where the cursor was advanced one position more than it should have been after showing an image
- Fix a bug where resizing panes by the Window > Resize Split Pane menu items would not always work if the panes had different fonts
- Don't expose the existence of the placeholder status bar component (used in empty status bars) in the context menu
