Version 1.9.15, 2011-03-21
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* First release candidate for 1.10.0
* Modify how message expansion is done in SHA-256 and SHA-512.
Instead of expanding the entire message at the start, compute them
in the minimum number of registers. Values are computed 15 rounds
before they are needed. On a Core i7-860, GCC 4.5.2, went from 143
to 157 MiB/s in SHA-256, and 211 to 256 MiB/s in SHA-512.
* Pipe will delete empty output queues as soon as they are no longer
needed, even if earlier messages still have data unread. However an
(empty) entry in a deque of pointers will remain until all prior
messages are completely emptied.
* Avoid reading the SPARC ``%tick`` register on OpenBSD as unlike the
Linux and NetBSD kernels, it will not trap and emulate it for us,
causing a illegal instruction crash.
* Improve detection and autoconfiguration for ARM processors. Thanks
go out to the the `Tahoe-LAFS Software Foundation
<http://tahoe-lafs.org>`_, who donated a Sheevaplug that I'll be
using to figure out how to make the cryptographic primitives
Tahoe-LAFS relies on faster, particularly targeting the ARMv5TE.
