 -------
 A modern SSH client for Mac OS 7/8/9.
 
-Project status: as of 0.8.0 ([see github releases](https://github.com/cy384/ssheven/releases)), a functional SSH client, able to connect via key or password.  Versions prior to 1.0.0 are alpha/beta quality.
+Project status: as of 0.8.0 ([see github releases](https://github.com/cy384/ssheven/releases)), fairly secure and usable, but without a polished UX or all planned features.  Versions prior to 1.0.0 should be considered alpha/beta quality.

-* CPU: Any PPC processor, or at least a 25 MHz 68040/68LC040.  Presently, all 68030 and 68020 CPUs are too slow.
+* CPU: Any PPC processor, or at least a 68030 (68040 strongly recommended).
 * RAM: 2MB.
 * Disk space: 1MB for the fat binary.
 * System 7.1 or later. Versions below 7.5 require the Thread Manager extension.

 * input latency feels high because redrawing the screen is slow
