- Update to 0.5.1:
* Added usage example for an ElligatorSwift key exchange.
* The default size of the precomputed table for signing was changed
from 22 KiB to 86 KiB. The size can be changed with the configure
option --ecmult-gen-kb (SECP256K1_ECMULT_GEN_KB for CMake).
* "auto" is no longer an accepted value for the --with-ecmult-window
and --with-ecmult-gen-kb configure options (this also applies to
SECP256K1_ECMULT_WINDOW_SIZE and SECP256K1_ECMULT_GEN_KB in CMake).
To achieve the same configuration as previously provided by the
"auto" value, omit setting the configure option explicitly.
* Fixed compilation when the extrakeys module is disabled.
* The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x.
