PLT Scheme v205 is now available from 



* DrScheme v205 provides a test case coverage tool. It is on by
  default in teaching languages.  Its purpose is to warn programmers
  of code that hasn't been exercised during execution or during
  interactive expression evaluations.  An integration of this feature
  with the test suite tool (see v204) is pending.

* This release also includes a hierarchy of syntacically restricted
  variants of Java, designed for teaching Java just like the HtDP
  languages are designed for teaching Scheme.  (The tool is not
  supported for MacOS Classic.)

* v205 is the last release that we plan to support for MacOS Classic.

* Anti-aliased fonts are now supported.

* PNG files are now fully supported (including alpha channels).

* Better OpenGL support; download the `sgl' addon for a higher-level

* Add-ons install into a user-specific directory by default.
