Two major versions followed; 1.0 of April 1994 was a major release that added 16-color ANSI support instead of 8-color, user-selected fonts including Shift JIS support, Kermit protocol support, and auto-opening of downloaded files. The latter was useful when used with offline mail readers like Blue Wave. Version 1.0.1, released in October 1995, was mostly a bug-fix release. By the time that macOS was being released around 2002, the BBS world had largely disappeared. However, a number of devices (including some routers and lab equipment) still use serial ports to communicate, typically for diagnostic and debugging purposes. On 19 April 2001, Alverson released version 1.1b4 that ran on Mac OS X 10.0, Mac OS 8.6 and Mac OS 9 using Carbon. Later a "Classic" version was released that did not require Carbon, allowing it to run on older machines that could not support Mac OS 8 or Mac OS 9. On 18 July 2011, Alverson released a Universal Binary version 1.2 that runs on Mac OS X 10.4 through Mac OS X 10.14. Because this version is not 64-bit, however, ZTerm will not run on Mac OS X 10.15 and above. On modern machines without built-in serial ports, ZTerm can identify and use a wide variety of USB-based serial devices. The list of supported hardware includes the standard Macintosh serial ports and Geoport on pre-PowerPC G3 CPU PowerPC Macintosh computers, the built-in Apple internal modem slot and the USB ports on PowerPC G3, PowerPC G4, PowerPC G5 and Intel-based Macintosh computers, and can be configured to work with adapters (including various USB port to serial port adaptors - such as those made by Keyspan, and Apple internal modem slot to serial port adaptors - like the Stealth Serial Port and the now discontinued Griffin Technology gPort, under OS X), giving it a unique use for BBSers and hardware tinkerers.
