Mac: iTerm has long been our favourite terminal emulator for the Mac, and over the weekend the next big update entered into public beta. It's packed with a ton of new features. The most noticeable feature is a new look, which put iTerm more in line with OS X design post-Yosemite. Beyond that, iTerm not gets optional Shell integration, automatic profile switching, badges, a new password manager and a ton of other smaller features. Of course, this is still a beta, so you might not want to use it as your daily driver terminal emulator, but it's still worth a look to see all the features that are on their way.
