Version 1.11.14, Not Yet Released
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* The global state object previously used by the library has been
removed and no form of initialization is required to use the library.
LibraryInitializer remains as a stub.
* The new `ffi` submodule provides a simple C API/ABI for a number of
useful operations (hashing, ciphers, public key operations, etc)
which is easily accessed using the FFI modules included in many
languages. A new Python wrapper using the Python `ctypes` module
is available. The old Boost.Python wrapper has been removed.
* OCB mode, which provides a fast and constant time AEAD mode without
requiring hardware support, is now supported in TLS, following
draft-zauner-tls-aes-ocb-01. Because this specification is not yet
finalized is not yet enabled by the default policy, and the
ciphersuite numbers used are in the experimental range and may
conflict with other uses.
* The memory usage of the counter mode implementation has been reduced.
* The memory allocator available on Unix systems which uses mmap and
mlock to lock a pool of memory now checks an environment variable
BOTAN_MLOCK_POOL_SIZE. If this is set to a smaller value then the
library would originally have allocated the user specified size is
used. You can also set it to zero to disable the pool entirely.
Previously the allocator would consume all available mlocked memory,
this allows botan to coexist with an application which wants to
mlock memory of its own.
* The botan-config script previously installed on Unix systems has
been removed. Its functionality is replaced by the `config` command
of the `botan` tool executable, for example `botan config cflags`
instead of `botan-config --cflags`.
