New in this release: Several small bug fixes
in the compiler. Update of the libraries to
incorporate the string types from module
`Object' into ADT:*, IO:*, OS:*, URI:*, and
(partially) XML:* modules. The internal
encoding of Unicode strings has been switched
to UTF-16. Support for the MacOS X and Win32
platforms has been improved.

The major new feature of this release is initial support
for parametric types. The semantics are loosely based
in the Generic Java specification. The definition of the
language extension can be found at http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/\*checkout*/ooc/ooc2/tests/doc/testcases_generics.txt?rev=HEAD&content-type=text/plain

The compiler now understands the `--uses' command,
similar to the command of the same name from the v1
oocn tool. Integration with Cygwin/Mingw32 has been
improved.

For the most part, this release fixes some
issues that crept in with the changes to config
file handling in 2.0.7. On the code generation
side, the compiler knows more about function
calls. See the change log for details.

Starting with this release, the front-end generates warnings for uses
of undefined variables, unreachable code, functions where control can
fall of the end, and unreachable WITH branches. This means that the
v2 warnings are finally pretty much in line with those of the old
processor.

This release also adds support for MinGW32 environment in various IO
modules (files, sockets, select, etc.) by Stewart Greenhill.
Configure with CPPFLAGS=-mno-cygwin and LDFLAGS=-mno-cygwin to use the
mingw32 model under cygwin.

The focus of this release is more efficient output code. Amongst
other things, it adds two code transformation stages, loop rewriting
(reassociation of sums and strength reduction on induction cycles) and
partial redundancy elimination. See the file release information for more
details.
