# CHANGELOG

## v2.2.0

* Register tags for `async_hook`s on `crypto_pwhash_*_async` functions
* Add constants and methods for `crypto_aead_xchacha20poly1305_ietf_*`. Please
  note the special circumstances around the bindings of `MESSAGEBYTES_MAX` and
  `crypto_aead_xchacha20poly1305_ietf_*_detached`.
* Improved error messages; now reports the constants and argument names
  documented from javascript.
* Use `Buffer.alloc`/`Buffer.fill`/`Buffer.from` in tests and examples
* Add more libsodium helpers; `sodium_memcmp`, `sodium_compare`, `sodium_add`,
  `sodium_increment`, `sodium_is_zero`
* Make it possible to pass only one of `rx` or `tx` to `crypto_kx_*`
* Add `crypto_scalarmult_ed25519_*` and `crypto_core_ed25519_*` operations

## v2.1.6

* Additional check `x < 0` before cast on uint assert macro
* Add prebuilds for Node 10

## v2.1.5

Fixes a critical bug in `crypto_secretstream_xchacha20poly1305_init_push` where
it would call `crypto_secretstream_xchacha20poly1305_init_pull` instead.

## v2.1.4

Only use the constants that `libsodium` compiled with instead of the ones that
`sodium-native` compiled with. This has caused bugs for some users and may have
led to subtle bugs.

## v2.1.3

Rework build process so it is more versatile on UNIX operating systems by
parsing the libtool archive files for correct .so name. This fixes builds on
OpenBSD (#54)

## v2.1.2

Fix `armv7l` builds.

## v2.1.1

A mistake was made in generating prebuilds for v2.1.0, this version resolves the
issue.

## v2.1.0
- Upgrade to libsodium 1.0.16
- Expose the new `crypto_secretstream` API
- Expose `crypto_kx` API
- Expose `sodium_pad` and `sodium_unpad` APIs
- Expose `crypto_pwhash_str_needs_rehash`
- Expose `randombytes_SEEDBYTES` `randombytes_random`, `randombytes_uniform` and
  `randombytes_buf_deterministic`
- Check for `NULL` on `sodium_malloc`
- All "Secure Buffers" (created with `sodium_malloc`) now have an immutable
  `.secure = true` property
