sbcl 2.0.9 introduced a new warning:
> minor incompatible change: the compiler signals a warning at
> compile-time when an initform of T, NIL or 0 does not match
> a STANDARD-CLASS slot's declared type.
This broke a few packages, but they all have been fixed upstream in the
meantime and we only need to bump their versions. The culprits are:
* defclass-std which possibly has become unmaintained since the fix
(december 2020).
* cl-prevalence which also needs one symbol from bt now
* lisp-binary which also includes a new file now
