Such an IV is treated + identically to an 8-byte IV of all zeros. + +* The PKCS11 module did not require any external dependencies, so it + has been enabled by default. The ``-with-pkcs11`` and ``--without-pkcs11`` + flags to ``configure.py`` have been removed. (GH #837) + +* Add ``OS::run_cpu_instruction_probe`` for runtime probing of ISA extensions. + Supporting this requires system-specific techniques, currently Windows SEH and + Unix signal handling are supported. + +* Add support for ARM NEON in the SIMD_4x32 type + +* Add support for ARM CPU feature detection using getauxval (GH #843) + +* Previously Botan forbid any use of times past 2037 to avoid Y2038 issues. + Now this restriction is only in place on systems which have a 32-bit + ``time_t``. (GH #933 fixing #917) + +* Add generic type decoder function to BER decoder (GH #897) + +* Fix portability or build problems affecting Sun Studio compiler (GH #846), + Solaris, ppc64le, DragonflyBSD (GH #887) + +* Add ``--with-external-libdir`` to configure.py (GH #857 fixing #19 #767) + +* Add ``OS::get_high_resolution_clock`` which returns the best resolution + clock available on the system. + +* Change ``OS::get_processor_timestamp`` to return 0 if no hardware + cycle counter is available. Previously it silently fell back on some + other clock type. + +* Report cycles/byte in the output of ``botan speed``. + +* Add speed tests for modular exponentiations and ECC scalar multiplies. + +* Make it possible to disable `-fstack-protector` using a build-time flag. + GH #863 + +* Add tests for TLS DSA ciphersuites, more Noekeon tests, others. + +* Avoid a GCC warning that triggered on the public key types (GH #849) + +* Fix various warnings flagged by pylint and pyflakes linters in + configure.py and botan.py (GH #832 #836 #839) + Version 1.10.15, 2017-01-12 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
