Remove preference to permanently silence multiline paste warning if the default action is cancel. Issue 5115.

Fix a bug where the color picker's eyedropper didn't work on any display other than screen 0. Issue 4821.

It didn't work well when another app became active (the popover overlapped it) or when a terminal window moved between the panel and the popover.

This reverts commit f783a5b7.

Fix incorrect tab filler orphan removal and tests that incorrectly assumed tab fillers followed a tab character. They precede it. Issue 5075

Remove table view delegate and data source in key mapping view controller to fix crash in issue 5080.

When exec fails show the command, why it failed, and if it failed because the file wasn't found, show the PATH that was searched

Fix a bug where iTerm2 would hang when a fd server exited before we attached to it (which could happen if the command failed to exec or exited right away). Also fix a leak of file descriptors (serverConnectionFd).

Remove WindowArrangements from NSNotificationCenter on dealloc, which crashes 10.10 and earlier when it posts kSavedArrangementDidChangeNotification when a dealloced instance is still observing notifications.

Modify release_beta to modify experiment files (testing3 and testing_changes3) so it's easy to roll changes out gradually to the population

Fix a crash on 10.9 and earlier when tabs don't have close buttons and the titles are long. Issue 4985

Fix a retain cycle in the keys prefs view controller that caused a crash when toggling the hotkey pinned button because a vc belonging to a now-dead window got a notification that something changed and asserted trying to get the info for the control.

Fix a bug where we tried to remove the window's first responder when a popover closes, but it was done wrong because in awakeFromNib the view did not yet have a window so the workaround was a no-op. Not sure if this used to work and then something changed, breaking it. The new code should be more robust because it gets the window from the color well, which we know must exist when its popover will close. This accounted for 20% of crashes in 3.0.5.

Fix a crash when you close prefs window while editing an untokenized value in the tags field. Mentioned in a comment in issue 4047.

Remove support for tmux's saved_cursor_x and saved_cursor_y, which were removed in tmux 2.1. Use alternate_saved_x and alternate_saved_y to set the saved cursor position in VT100Terminal when attaching to a tmux window pane. Fixes a bug where the cursor position isn't correctly restored. Issue 5025.

Support ipv6 DNS lookups for determining if a hostname is legit for semantic history. Don't cache temporary DNS failures.
