* Version 1.0.18

 - The Enterprise versions of Visual Studio are now supported.

 - Visual Studio 2019 is now supported.

 - 32-bit binaries for Visual Studio 2010 are now provided.

 - A test that didn't work properly on Linux systems with overcommit

memory turned on has been removed. This fixes Ansible builds.

 - Emscripten: `print` and `printErr` functions are overridden to send

errors to the console, if there is one.

 - Emscripten: `UTF8ToString()` is now exported since `Pointer_stringify()`

has been deprecated.

 - Libsodium version detection has been fixed in the CMake recipe.

 - Generic hashing got a 10% speedup on AVX2.

 - New target: WebAssembly/WASI (compile with `dist-builds/wasm32-wasi.sh`).

 - New functions to map a hash to an edwards25519 point or get a random point:

`core_ed25519_from_hash()` and `core_ed25519_random()`.

 - `crypto_core_ed25519_scalar_mul()` has been implemented for `scalar*scalar`

`(mod L)` multiplication.

 - Support for the Ristretto group has been implemented, for compatibility

with wasm-crypto.

 - Improvements have been made to the test suite.

 - Portability improvements has been made.

 - `getentropy()` is now used on systems providing this system call.

 - `randombytes_salsa20 has been renamed to `randombytes_internal`.

 - Support for (p)nacl has been removed.

 - Most `((nonnull))` attributes have been relaxed to allow 0-length inputs

to be `NULL`.

 - The `-ftree-vectorize` and `-ftree-slp-vectorize` compiler switches are

now used, if available, for optimized builds.

* Version 1.0.17

 - Bug fix: `sodium_pad()` didn't properly support block sizes >= 256 bytes.

 - JS/WebAssembly: some old iOS versions can't instantiate the WebAssembly

module; fall back to Javascript on these.

 - JS/WebAssembly: compatibility with newer Emscripten versions.

 - Bug fix: `crypto_pwhash_scryptsalsa208sha256_str_verify()` and

`crypto_pwhash_scryptsalsa208sha256_str_needs_rehash()` didn't return

`EINVAL` on input strings with a short length, unlike their high-level

counterpart.

 - Added a workaround for Visual Studio 2010 bug causing CPU features

not to be detected.

 - Portability improvements.

 - Test vectors from Project Wycheproof have been added.

 - New low-level APIs for arithmetic mod the order of the prime order group:

`crypto_core_ed25519_scalar_random()`, `crypto_core_ed25519_scalar_reduce()`,

`crypto_core_ed25519_scalar_invert()`, `crypto_core_ed25519_scalar_negate()`,

`crypto_core_ed25519_scalar_complement()`, `crypto_core_ed25519_scalar_add()`

and `crypto_core_ed25519_scalar_sub()`.

 - New low-level APIs for scalar multiplication without clamping:

`crypto_scalarmult_ed25519_base_noclamp()` and

`crypto_scalarmult_ed25519_noclamp()`. These new APIs are especially useful

for blinding.

 - `sodium_sub()` has been implemented.

 - Support for WatchOS has been added.

 - getrandom(2) is now used on FreeBSD 12+.

 - The `nonnull` attribute has been added to all relevant prototypes.

 - More reliable AVX512 detection.

 - Javascript/Webassembly builds now use dynamic memory growth.

* Version 1.0.16

 - Signatures computations and verifications are now way faster on

64-bit platforms with compilers supporting 128-bit arithmetic (gcc,

clang, icc). This includes the WebAssembly target.

 - New low-level APIs for computations over edwards25519:

`crypto_scalarmult_ed25519()`, `crypto_scalarmult_ed25519_base()`,

`crypto_core_ed25519_is_valid_point()`, `crypto_core_ed25519_add()`,

`crypto_core_ed25519_sub()` and `crypto_core_ed25519_from_uniform()`

(elligator representative to point).

 - `crypto_sign_open()`, `crypto_sign_verify_detached() and

`crypto_sign_edwards25519sha512batch_open` now reject public keys in

non-canonical form in addition to low-order points.

 - The library can be built with `ED25519_NONDETERMINISTIC` defined in

order to use synthetic nonces for EdDSA. This is disabled by default.

 - Webassembly: `crypto_pwhash_*()` functions are now included in

non-sumo builds.

 - `sodium_stackzero()` was added to wipe content off the stack.

 - Android: support new SDKs where unified headers have become the

default.

 - The Salsa20-based PRNG example is now thread-safe on platforms with

support for thread-local storage, optionally mixes bits from RDRAND.

 - CMAKE: static library detection on Unix systems has been improved

(thanks to @BurningEnlightenment, @nibua-r, @mellery451)

 - Argon2 and scrypt are slightly faster on Linux.

* Version 1.0.15

 - The default password hashing algorithm is now Argon2id. The

`pwhash_str_verify()` function can still verify Argon2i hashes

without any changes, and `pwhash()` can still compute Argon2i hashes

as well.

 - The aes128ctr primitive was removed. It was slow, non-standard, not

authenticated, and didn't seem to be used by any opensource project.

 - Argon2id required at least 3 passes like Argon2i, despite a minimum

of `1` as defined by the `OPSLIMIT_MIN` constant. This has been fixed.

 - The secretstream construction was slightly changed to be consistent

with forthcoming variants.

 - The Javascript and Webassembly versions have been merged, and the

module now returns a `.ready` promise that will resolve after the

Webassembly code is loaded and compiled.

 - Note that due to these incompatible changes, the library version

major was bumped up.

* Version 1.0.14

 - iOS binaries should now be compatible with WatchOS and TVOS.

 - WebAssembly is now officially supported. Special thanks to

@facekapow and @pepyakin who helped to make it happen.

 - Internal consistency checks failing and primitives used with

dangerous/out-of-bounds/invalid parameters used to call abort(3).

Now, a custom handler *that doesn't return* can be set with the

`set_sodium_misuse()` function. It still aborts by default or if the

handler ever returns. This is not a replacement for non-fatal,

expected runtime errors. This handler will be only called in

unexpected situations due to potential bugs in the library or in

language bindings.

 - `*_MESSAGEBYTES_MAX` macros (and the corresponding

`_messagebytes_max()` symbols) have been added to represent the

maximum message size that can be safely handled by a primitive.

Language bindings are encouraged to check user inputs against these

maximum lengths.

 - The test suite has been extended to cover more edge cases.

 - crypto_sign_ed25519_pk_to_curve25519() now rejects points that are

not on the curve, or not in the main subgroup.

 - Further changes have been made to ensure that smart compilers will

not optimize out code that we don't want to be optimized.

 - Visual Studio solutions are now included in distribution tarballs.

 - The `sodium_runtime_has_*` symbols for CPU features detection are

now defined as weak symbols, i.e. they can be replaced with an

application-defined implementation. This can be useful to disable

AVX* when temperature/power consumption is a concern.

 - `crypto_kx_*()` now aborts if called with no non-NULL pointers to

store keys to.

 - SSE2 implementations of `crypto_verify_*()` have been added.

 - Passwords can be hashed using a specific algorithm with the new

`crypto_pwhash_str_alg()` function.

 - Due to popular demand, base64 encoding (`sodium_bin2base64()`) and

decoding (`sodium_base642bin()`) have been implemented.

 - A new `crypto_secretstream_*()` API was added to safely encrypt files

and multi-part messages.

 - The `sodium_pad()` and `sodium_unpad()` helper functions have been

added in order to add & remove padding.

 - An AVX512 optimized implementation of Argon2 has been added (written

by Ondrej Mosnáček, thanks!)

 - The `crypto_pwhash_str_needs_rehash()` function was added to check if

a password hash string matches the given parameters, or if it needs an

update.

 - The library can now be compiled with recent versions of

emscripten/binaryen that don't allow multiple variables declarations

using a single `var` statement.

* Version 1.0.13

 - Javascript: the sumo builds now include all symbols. They were

previously limited to symbols defined in minimal builds.

 - The public `crypto_pwhash_argon2i_MEMLIMIT_MAX` constant was

incorrectly defined on 32-bit platforms. This has been fixed.

 - Version 1.0.12 didn't compile on OpenBSD/i386 using the base gcc

compiler. This has been fixed.

 - The Android compilation scripts have been updated for NDK r14b.

 - armv7s-optimized code was re-added to iOS builds.

 - An AVX2 optimized implementation of the Argon2 round function was

added.

 - The Argon2id variant of Argon2 has been implemented. The

high-level `crypto_pwhash_str_verify()` function automatically detects

the algorithm and can verify both Argon2i and Argon2id hashed passwords.

The default algorithm for newly hashed passwords remains Argon2i in

this version to avoid breaking compatibility with verifiers running

libsodium <= 1.0.12.

 - A `crypto_box_curve25519xchacha20poly1305_seal*()` function set was

implemented.

 - scrypt was removed from minimal builds.

 - libsodium is now available on NuGet.

* Version 1.0.12

 - Ed25519ph was implemented, adding a multi-part signature API

(`crypto_sign_init()`, `crypto_sign_update()`, `crypto_sign_final_*()`).

 - New constants and related accessors have been added for Scrypt and

Argon2.

 - XChaCha20 has been implemented. Like XSalsa20, this construction

extends the ChaCha20 cipher to accept a 192-bit nonce. This makes it safe

to use ChaCha20 with random nonces.

 - `crypto_secretbox`, `crypto_box` and `crypto_aead` now offer

variants leveraging XChaCha20.

 - SHA-2 is about 20% faster, which also gives a speed boost to

signature and signature verification.

 - AVX2 implementations of Salsa20 and ChaCha20 have been added. They

are twice as fast as the SSE2 implementations. The speed gain is

even more significant on Windows, that previously didn't use

vectorized implementations.

 - New high-level API: `crypto_kdf`, to easily derive one or more

subkeys from a master key.

 - Siphash with a 128-bit output has been implemented, and is

available as `crypto_shorthash_siphashx_*`.

 - New `*_keygen()` helpers functions have been added to create secret

keys for all constructions. This improves code clarity and can prevent keys

from being partially initialized.

 - A new `randombytes_buf_deterministic()` function was added to

deterministically fill a memory region with pseudorandom data. This

function can especially be useful to write reproducible tests.

 - A preliminary `crypto_kx_*()` API was added to compute shared session

keys.

 - AVX2 detection is more reliable.

 - The pthreads library is not required any more when using MingW.

 - `contrib/Findsodium.cmake` was added as an example to include

libsodium in a project using cmake.

 - Compatibility with gcc 2.x has been restored.

 - Minimal builds can be checked using `sodium_library_minimal()`.

 - The `--enable-opt` compilation switch has become compatible with more

platforms.

 - Android builds are now using clang on platforms where it is

available.

* Version 1.0.11

 - `sodium_init()` is now thread-safe, and can be safely called multiple

times.

 - Android binaries now properly support 64-bit Android, targeting

platform 24, but without breaking compatibility with platforms 16 and

21.

 - Better support for old gcc versions.

 - On FreeBSD, core dumps are disabled on regions allocated with

sodium allocation functions.

 - AVX2 detection was fixed, resulting in faster Blake2b hashing on

platforms where it was not properly detected.

 - The Sandy2x Curve25519 implementation was not as fast as expected

on some platforms. This has been fixed.

 - The NativeClient target was improved. Most notably, it now supports

optimized implementations, and uses pepper_49 by default.

 - The library can be compiled with recent Emscripten versions.

Changes have been made to produce smaller code, and the default heap

size was reduced in the standard version.

 - The code can now be compiled on SLES11 service pack 4.

 - Decryption functions can now accept a NULL pointer for the output.

This checks the MAC without writing the decrypted message.

 - crypto_generichash_final() now returns -1 if called twice.

 - Support for Visual Studio 2008 was improved.

* Version 1.0.10

 - This release only fixes a compilation issue reported with some older

gcc versions. There are no functional changes over the previous release.

* Version 1.0.9

 - The Javascript target now includes a `--sumo` option to include all

the symbols of the original C library.

 - A detached API was added to the ChaCha20-Poly1305 and AES256-GCM

implementations.

 - The Argon2i password hashing function was added, and is accessible

directly and through a new, high-level `crypto_pwhash` API. The scrypt

function remains available as well.

 - A speed-record AVX2 implementation of BLAKE2b was added (thanks to

Samuel Neves).

 - The library can now be compiled using C++Builder (thanks to @jcolli44)

 - Countermeasures for Ed25519 signatures malleability have been added

to match the irtf-cfrg-eddsa draft (note that malleability is irrelevant to

the standard definition of signature security). Signatures with a small-order

`R` point are now also rejected.

 - Some implementations are now slightly faster when using the Clang

compiler.

 - The HChaCha20 core function was implemented (`crypto_core_hchacha20()`).

 - No-op stubs were added for all AES256-GCM public functions even when

compiled on non-Intel platforms.

 - `crypt_generichash_blake2b_statebytes()` was added.

 - New macros were added for the IETF variant of the ChaCha20-Poly1305

construction.

 - The library can now be compiled on Minix.

 - HEASLR is now enabled on MinGW builds.

* Version 1.0.8

 - Handle the case where the CPU supports AVX, but we are running

on an hypervisor with AVX disabled/not supported.

 - Faster (2x) scalarmult_base() when using the ref10 implementation.

* Version 1.0.7

 - More functions whose return value should be checked have been

tagged with `__attribute__ ((warn_unused_result))`: `crypto_box_easy()`,

`crypto_box_detached()`, `crypto_box_beforenm()`, `crypto_box()`, and

`crypto_scalarmult()`.

 - Sandy2x, the fastest Curve25519 implementation ever, has been

merged in, and is automatically used on CPUs supporting the AVX

instructions set.

 - An SSE2 optimized implementation of Poly1305 was added, and is

twice as fast as the portable one.

 - An SSSE3 optimized implementation of ChaCha20 was added, and is

twice as fast as the portable one.

 - Faster `sodium_increment()` for common nonce sizes.

 - New helper functions have been added: `sodium_is_zero()` and

 `sodium_add()`.

 - `sodium_runtime_has_aesni()` now properly detects the CPU flag when

 compiled using Visual Studio.

* Version 1.0.6

 - Optimized implementations of Blake2 have been added for modern

Intel platforms. `crypto_generichash()` is now faster than MD5 and SHA1

implementations while being far more secure.

 - Functions for which the return value should be checked have been

tagged with `__attribute__ ((warn_unused_result))`. This will

intentionally break code compiled with `-Werror` that didn't bother

checking critical return values.

 - The `crypto_sign_edwards25519sha512batch_*()` functions have been

tagged as deprecated.

 - Undocumented symbols that were exported, but were only useful for

internal purposes have been removed or made private:

`sodium_runtime_get_cpu_features()`, the implementation-specific

`crypto_onetimeauth_poly1305_donna()` symbols,

`crypto_onetimeauth_poly1305_set_implementation()`,

`crypto_onetimeauth_poly1305_implementation_name()` and

`crypto_onetimeauth_pick_best_implementation()`.

 - `sodium_compare()` now works as documented, and compares numbers

in little-endian format instead of behaving like `memcmp()`.

 - The previous changes should not break actual applications, but to be

safe, the library version major was incremented.

 - `sodium_runtime_has_ssse3()` and `sodium_runtime_has_sse41()` have

been added.

 - The library can now be compiled with the CompCert compiler.

* Version 1.0.5

 - Compilation issues on some platforms were fixed: missing alignment

directives were added (required at least on RHEL-6/i386), a workaround

for a VRP bug on gcc/armv7 was added, and the library can now be compiled

with the SunPro compiler.

 - Javascript target: io.js is not supported any more. Use nodejs.

* Version 1.0.4

 - Support for AES256-GCM has been added. This requires

a CPU with the aesni and pclmul extensions, and is accessible via the

crypto_aead_aes256gcm_*() functions.

 - The Javascript target doesn't use eval() any more, so that the

library can be used in Chrome packaged applications.

 - QNX and CloudABI are now supported.

 - Support for NaCl has finally been added.

 - ChaCha20 with an extended (96 bit) nonce and a 32-bit counter has

been implemented as crypto_stream_chacha20_ietf(),

crypto_stream_chacha20_ietf_xor() and crypto_stream_chacha20_ietf_xor_ic().

An IETF-compatible version of ChaCha20Poly1305 is available as

crypto_aead_chacha20poly1305_ietf_npubbytes(),

crypto_aead_chacha20poly1305_ietf_encrypt() and

crypto_aead_chacha20poly1305_ietf_decrypt().

 - The sodium_increment() helper function has been added, to increment

an arbitrary large number (such as a nonce).

 - The sodium_compare() helper function has been added, to compare

arbitrary large numbers (such as nonces, in order to prevent replay

attacks).

* Version 1.0.3

 - In addition to sodium_bin2hex(), sodium_hex2bin() is now a

constant-time function.

 - crypto_stream_xsalsa20_ic() has been added.

 - crypto_generichash_statebytes(), crypto_auth_*_statebytes() and

crypto_hash_*_statebytes() have been added in order to retrieve the

size of structures keeping states from foreign languages.

 - The JavaScript target doesn't require /dev/urandom or an external

randombytes() implementation any more. Other minor Emscripten-related

improvements have been made in order to support libsodium.js

 - Custom randombytes implementations do not need to provide their own

implementation of randombytes_uniform() any more. randombytes_stir()

and randombytes_close() can also be NULL pointers if they are not

required.

 - On Linux, getrandom(2) is being used instead of directly accessing

/dev/urandom, if the kernel supports this system call.

 - crypto_box_seal() and crypto_box_seal_open() have been added.

 - Visual Studio 2015 is now supported.

* Version 1.0.2

 - The _easy and _detached APIs now support precalculated keys;

crypto_box_easy_afternm(), crypto_box_open_easy_afternm(),

crypto_box_detached_afternm() and crypto_box_open_detached_afternm()

have been added as an alternative to the NaCl interface.

 - Memory allocation functions can now be used on operating systems with

no memory protection.

 - crypto_sign_open() and crypto_sign_edwards25519sha512batch_open()

now accept a NULL pointer instead of a pointer to the message size, if

storing this information is not required.

 - The close-on-exec flag is now set on the descriptor returned when

opening /dev/urandom.

 - A libsodium-uninstalled.pc file to use pkg-config even when

libsodium is not installed, has been added.

 - The iOS target now includes armv7s and arm64 optimized code, as well

as i386 and x86_64 code for the iOS simulator.

 - sodium_free() can now be called on regions with PROT_NONE protection.

 - The Javascript tests can run on Ubuntu, where the node binary was

renamed nodejs. io.js can also be used instead of node.

* Version 1.0.1

 - DLL_EXPORT was renamed SODIUM_DLL_EXPORT in order to avoid

collisions with similar macros defined by other libraries.

 - sodium_bin2hex() is now constant-time.

 - crypto_secretbox_detached() now supports overlapping input and output

regions.

 - NaCl's donna_c64 implementation of curve25519 was reading an extra byte

past the end of the buffer containing the base point. This has been

fixed.

* Version 1.0.0

 - The API and ABI are now stable. New features will be added, but

backward-compatibility is guaranteed through all the 1.x.y releases.

 - crypto_sign() properly works with overlapping regions again. Thanks

to @pysiak for reporting this regression introduced in version 0.6.1.

 - The test suite has been extended.

* Version 0.7.1 (1.0 RC2)

 - This is the second release candidate of Sodium 1.0. Minor

compilation, readability and portability changes have been made and the

test suite was improved, but the API is the same as the previous release

candidate.

* Version 0.7.0 (1.0 RC1)

 - Allocating memory to store sensitive data can now be done using

sodium_malloc() and sodium_allocarray(). These functions add guard

pages around the protected data to make it less likely to be

accessible in a heartbleed-like scenario. In addition, the protection

for memory regions allocated that way can be changed using

sodium_mprotect_noaccess(), sodium_mprotect_readonly() and

sodium_mprotect_readwrite().

 - ed25519 keys can be converted to curve25519 keys with

crypto_sign_ed25519_pk_to_curve25519() and

crypto_sign_ed25519_sk_to_curve25519(). This allows using the same

keys for signature and encryption.

 - The seed and the public key can be extracted from an ed25519 key

using crypto_sign_ed25519_sk_to_seed() and crypto_sign_ed25519_sk_to_pk().

 - aes256 was removed. A timing-attack resistant implementation might

be added later, but not before version 1.0 is tagged.

 - The crypto_pwhash_scryptxsalsa208sha256_* compatibility layer was

removed. Use crypto_pwhash_scryptsalsa208sha256_*.

 - The compatibility layer for implementation-specific functions was

removed.

 - Compilation issues with Mingw64 on MSYS (not MSYS2) were fixed.

 - crypto_pwhash_scryptsalsa208sha256_STRPREFIX was added: it contains

the prefix produced by crypto_pwhash_scryptsalsa208sha256_str()

* Version 0.6.1

 - Important bug fix: when crypto_sign_open() was given a signed

message too short to even contain a signature, it was putting an

unlimited amount of zeros into the target buffer instead of

immediately returning -1. The bug was introduced in version 0.5.0.

 - New API: crypto_sign_detached() and crypto_sign_verify_detached()

to produce and verify ed25519 signatures without having to duplicate

the message.

 - New ./configure switch: --enable-minimal, to create a smaller

library, with only the functions required for the high-level API.

Mainly useful for the JavaScript target and embedded systems.

 - All the symbols are now exported by the Emscripten build script.

 - The pkg-config .pc file is now always installed even if the

pkg-config tool is not available during the installation.

* Version 0.6.0

 - The ChaCha20 stream cipher has been added, as crypto_stream_chacha20_*

 - The ChaCha20Poly1305 AEAD construction has been implemented, as

crypto_aead_chacha20poly1305_*

 - The _easy API does not require any heap allocations any more and

does not have any overhead over the NaCl API. With the password

hashing function being an obvious exception, the library doesn't

allocate and will not allocate heap memory ever.

 - crypto_box and crypto_secretbox have a new _detached API to store

the authentication tag and the encrypted message separately.

 - crypto_pwhash_scryptxsalsa208sha256*() functions have been renamed

crypto_pwhash_scryptsalsa208sha256*().

 - The low-level crypto_pwhash_scryptsalsa208sha256_ll() function

allows setting individual parameters of the scrypt function.

 - New macros and functions for recommended crypto_pwhash_* parameters

have been added.

 - Similarly to crypto_sign_seed_keypair(), crypto_box_seed_keypair()

has been introduced to deterministically generate a key pair from a seed.

 - crypto_onetimeauth() now provides a streaming interface.

 - crypto_stream_chacha20_xor_ic() and crypto_stream_salsa20_xor_ic()

have been added to use a non-zero initial block counter.

 - On Windows, CryptGenRandom() was replaced by RtlGenRandom(), which

doesn't require the Crypt API.

 - The high bit in curve25519 is masked instead of processing the key as

a 256-bit value.

 - The curve25519 ref implementation was replaced by the latest ref10

implementation from Supercop.

 - sodium_mlock() now prevents memory from being included in coredumps

on Linux 3.4+

* Version 0.5.0

 - sodium_mlock()/sodium_munlock() have been introduced to lock pages

in memory before storing sensitive data, and to zero them before

unlocking them.

 - High-level wrappers for crypto_box and crypto_secretbox

(crypto_box_easy and crypto_secretbox_easy) can be used to avoid

dealing with the specific memory layout regular functions depend on.

 - crypto_pwhash_scryptsalsa208sha256* functions have been added

to derive a key from a password, and for password storage.

 - Salsa20 and ed25519 implementations now support overlapping

inputs/keys/outputs (changes imported from supercop-20140505).

 - New build scripts for Visual Studio, Emscripten, different Android

architectures and msys2 are available.

 - The poly1305-53 implementation has been replaced with Floodyberry's

poly1305-donna32 and poly1305-donna64 implementations.

 - sodium_hex2bin() has been added to complement sodium_bin2hex().

 - On OpenBSD and Bitrig, arc4random() is used instead of reading

/dev/urandom.

 - crypto_auth_hmac_sha512() has been implemented.

 - sha256 and sha512 now have a streaming interface.

 - hmacsha256, hmacsha512 and hmacsha512256 now support keys of

arbitrary length, and have a streaming interface.

 - crypto_verify_64() has been implemented.

 - first-class Visual Studio build system, thanks to @evoskuil

 - CPU features are now detected at runtime.

* Version 0.4.5

 - mingw64 is now supported

 - big-endian architectures are now supported as well

 - The donna_c64 implementation of curve25519_donna_c64 now handles

non-canonical points like the ref implementation

 - Missing scalarmult_curve25519 and stream_salsa20 constants are now exported

 - A crypto_onetimeauth_poly1305_ref() wrapper has been added

* Version 0.4.3

 - crypto_sign_seedbytes() and crypto_sign_SEEDBYTES were added.

 - crypto_onetimeauth_poly1305_implementation_name() was added.

 - poly1305-ref has been replaced by a faster implementation,

Floodyberry's poly1305-donna-unrolled.

 - Stackmarkings have been added to assembly code, for Hardened Gentoo.

 - pkg-config can now be used in order to retrieve compilations flags for

using libsodium.

 - crypto_stream_aes256estream_*() can now deal with unaligned input

on platforms that require word alignment.

 - portability improvements.

* Version 0.4.2

 - All NaCl constants are now also exposed as functions.

 - The Android and iOS cross-compilation script have been improved.

 - libsodium can now be cross-compiled to Windows from Linux.

 - libsodium can now be compiled with emscripten.

 - New convenience function (prototyped in utils.h): sodium_bin2hex().

* Version 0.4.1

 - sodium_version_*() functions were not exported in version 0.4. They

are now visible as intended.

 - sodium_init() now calls randombytes_stir().

 - optimized assembly version of salsa20 is now used on amd64.

 - further cleanups and enhanced compatibility with non-C99 compilers.

* Version 0.4

 - Most constants and operations are now available as actual functions

instead of macros, making it easier to use from other languages.

 - New operation: crypto_generichash, featuring a variable key size, a

variable output size, and a streaming API. Currently implemented using

Blake2b.

 - The package can be compiled in a separate directory.

 - aes128ctr functions are exported.

 - Optimized versions of curve25519 (curve25519_donna_c64), poly1305

(poly1305_53) and ed25519 (ed25519_ref10) are available. Optionally calling

sodium_init() once before using the library makes it pick the fastest

implementation.

 - New convenience function: sodium_memzero() in order to securely

wipe a memory area.
