[cmucl-imp] CMUCL 20d released

[Raymond Toy]

CMUCL 20d has been released.  It is functionally identical to the
2012-10 snapshot.  Binaries will be uploaded shortly, and the website
updated soon.

With this release, there will NOT be a 2012-11 snapshot. 

Also, this release marks the end of support 8-bit characters; only
Unicode will be supported from now on.  Support for x87 will remain,
however.

Hope this release is useful to you.
