If you use an older and unsupported macOS version, you can try version 4.0.0.
Changes in 2017
New in 20170607:
Fixed a problem where animation frames would always have rectangular corners, even for shaped windows.
Animations are generally faster now.
New in 20170515:
Fixed Undo and Redo commands in certain text fields such as the floating Command Line.
Undo and Redo can once again be used for changes made with "Custom Screen Size...".
The "Custom Terminal Setup..." command has been removed (it was never implemented and always emitted an error sound when used). Several terminal settings can be changed dynamically using the commands in the Terminal menu. Screen dimensions can be changed with the "Custom Screen Size..." command in the View menu.
New in 20170511:
Macros with an Action of "Find in Local Terminal Verbatim" or "Find in Local Terminal with Substitutions" will now cause automatic scrolling when invoked, just like a normal search would do. This allows you to write macros that jump back to a certain point in the scrollback, for example, based on a pattern match.
New in 20170330:
Preferences window toolbar now has pop-up menu short-cuts to display particular tabs within a category. The button icon can be pressed for normal behavior, and the menu portion can be used to go directly to a tab.
New in 20170324:
Support for Voice Over and related technologies has significantly improved, as accessibility descriptions have been added to a wide variety of user interface elements. Voice Over will now clearly identify the effect of any control (such as, the group of settings that the control belongs to). Also, some controls that previously had no label at all are now identified by Voice Over.
New in 20170307:
Fixed keyboard navigation behavior when using Full Keyboard Access in some panels of the Preferences window and corresponding sheets. Previously, there were locations that stopped recognizing Tab key-presses.
Fixed a few remaining cases of incorrectly-rendered focus rings when using Full Keyboard Access to activate controls in the Preferences window and corresponding sheets.
New in 20170112:
Fixed terminal view text selection in the scrollback buffer, which was off by one line in some recent builds.
Fixed terminal view text selections to correctly auto-scroll the terminal in either direction when moving past the top or bottom.
