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.
