Yes, you heard right, it's 1.0.0... :)
This is basically the second part of the redesign I started a couple of days ago. FLEXI-STREAMS should now be faster than before and it should also do more error checking (illegal code points, overlong sequences, and so on).
The code has been tested (using the test suite that comes with the library) on LispWorks, AllegroCL, SBCL, and ClozureCL (with the versions I happened to have installed on my machine). As usual with dot-zero releases you should expect bugs, though. Keep the old versions that are working for you and test this release before you use it.
Have fun, Edi.
