### Changes between 3.2.0 and 3.2.1 [xx XXX xxxx]
* The POLY1305 MAC (message authentication code) implementation in OpenSSL
for PowerPC CPUs saves the contents of vector registers in different
order than they are restored. Thus the contents of some of these vector
registers is corrupted when returning to the caller. The vulnerable code is
used only on newer PowerPC processors supporting the PowerISA 2.07
instructions.
The consequences of this kind of internal application state corruption can
be various - from no consequences, if the calling application does not
depend on the contents of non-volatile XMM registers at all, to the worst
consequences, where the attacker could get complete control of the
application process. However unless the compiler uses the vector registers
for storing pointers, the most likely consequence, if any, would be an
incorrect result of some application dependent calculations or a crash
leading to a denial of service.

* Disable building QUIC server utility when OpenSSL is configured with
`no-apps`.
