iTerm2 3.3.7

What's new in this version:

New Features:
- Adds a preference to specify whether you want each tab to control the window title separately, or if all tabs in a window should share a single window title. This affects window title set by control sequences like OSC 2
- Separate 'use custom bold color' from 'brighten bold colors', which previously were confusingly grouped into a single setting
- Password manager now has a column for user names
- Add support for 2-factor codes appended to password in password manager

Improvements:
- Various performance improvements
- When the window title is changed by a control sequence, set the window title to exactly that string
- Remember whether "tags" view of profile list is expanded in toolbelt
- Move selection-related settings into General > Selection
- Add advanced pref to disable tabbar tooltips
- Set pixel size in TTY
- Don't show a warning when modifying a session's copy of its profile when that profile is backed by a dynamic profile
- When prefs from a remote location fail to load, offer to reveal the responsible preference
- The toolbelt now uses a dark background in the Minimal theme when the terminal window's background is dark
- Add Unicode 12 width tables for emoji
- Add "Edit Account Name" and "Edit User Name" to password manager context menu
- Variable-size tmux windows are now pretty usable. Try turning on Prefs>Advanced>Allow variable window sizes in tmux integration
- Put a dot in the close button when there is an active job running
- You can now drag the window using the New Tab + button
- When selecting a tag from the "tags" view, use the tag: operator to restrict the search term to tags
- Add advanced pref to enable italic in tmux integration. It uses the "screen" terminal where the control sequence normally used for italics instead does reverse video

Bug Fixes:
- Disable quicklook if it's disabled systemwide
- Fix drawing of "tags" view of profile list
- Fix bug where users with spaces in their names couldn't log in
- Fix a bug where windows with a left-side tab bar had the wrong number of columns when first created
- Fix a bug where activating a session via API in an inactive tab would activate the wrong session in that tab
- Fix a bug where setting the icon title when showing Profile + Session name caused the profile name to go away
- Fix padding of "broken pipe" message
- Fix bugs in updating session list in tmux dashboard
- Fix a bug where window buttons were hidden when entering native full screen
- Disable selection scroll if it begins in the mutable area while reporting mouse clicks
- Fix a bug where option-clicking the zoom button after exiting full screen doesn't zoom
- Fix a bug where selection by dragging three fingers selects too much text
- Fix imgcat in Catalina
- Fix dragging folders to iTerm2 icon
- Remove a brittle performance hack for scroll views that may have been causing crashes
- Fix a bug when changing tabs while selecting text causing future selections to be wrong
- Fix a few crashes
- Fix manpage viewer in touch bar
- If you use the CurrentDir control sequence without the rest of shell integration, it will now work reliably
- Fix escaping of smart selection "run command in window" commands
- Fix some integer overflow bugs
- In secure copy, keyboard-interactive and private key passpharse input deadlocked. Fix it
- Preserve the selected weight when changing typeface, when possible
- Respect the desired popover size for custom status bar components. This fix may cause some popovers to have different-sized popovers than
expected, and may require updating the script to correct
- Fix a bug where Find Next would not navigate to the very first word in history
- Fix a runaway CPU issue when initializing GPU renderer
- Touch bar in full screen now shows correct tab titles. Fixes a bug where they would get out of sync with reality
- Fixes a bug where adding a new password in the password manager could hang

Scripting:
- Python 3.8.0 is now available. It requires 3.3.7beta3 or later, so keep that in mind when distributing scripts
- Add support for delta updates of the Python runtime
- Add Session.async_get_contents to docs
- Add Profile.async_get_default and PartialProfile.async_get_default
