^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-* The global state object previously used by the library has been removed and no
- form of initialization is required to use the library. The global PRNG has
- also been removed. LibraryInitializer remains as a stub.
+* The global state object previously used by the library has been removed.
+ This includes the global PRNG. The library can be safely initialized
+ multiple times without harm.
The engine code has also been removed, replaced by a much lighter-weight
object registry system which provides lookups in faster time and with less
memory overhead than the previous approach.
+ One caveat of the current system with regards to static linking: because only
+ symbols already mentioned elsewhere in the program are included in the final
+ link step, few algorithms will be available through the lookup system by
+ default, even though they were compiled into the library. Your application
+ must explicitly reference the types you require or they will not end up
+ being available in the final binary. See also Github issue #52
+
+ If you intend to build your application against a static library and don't
+ want to explicitly reference each algo object you might attempt to look up by
+ string, consider either building with `--via-amalgamation`, or else (much
+ simpler) using the amalgamation directly.

* 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.

-* PBKDF and KDF operations now provide a way to write the desired output

-* HKDF, previously provided using a non-standard interface, now uses the
- standard KDF interface and is retreivable using get_kdf.
+* Add specialized reducers for P-192, P-224, P-256, and P-384

hardware support, is now supported in TLS, following

+* The amalgamation now splits off any ISA specific code (for instance, that
+ requiring SSSE3 instruction sets) into a new file named (for instance)
+ `botan_all_ssse3.cpp`. This allows the main amalgamation file to be compiled
+ without any special flags, so `--via-amalgamation` builds actually work now.

+* It is once again possible to build the complete test suite without requiring
+ any boost libraries. This is currently only supported on systems supporting
+ the readdir interface.
* Remove use of memset_s which caused problems with amalgamation on OS X.

* The memory usage of the counter mode implementation has been reduced.
+ Previously it encrypted 256 blocks in parallel as this leads to a slightly
+ faster counter increment operation. Instead CTR_BE simply encrypts a buffer
+ equal in size to the advertised parallelism of the cipher implementation.
+ This is not measurably slower, and dramatically reduces the memory use of
+ CTR mode.
* 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.
