LibreSSL Portable Release Notes:
2.8.1 - Test and compatibility improvements
* Added Wycheproof test vectors for ECDH, RSASSA-PSS, AES-GCM,
AES-CMAC, AES-CCM, AES-CBC-PKCS5, DSA, ChaCha20-Poly1305, ECDSA,
X25519, and applied appropriate fixes for errors uncovered by tests.
* Simplified key exchange signature generation and verification.
* Fixed a one-byte buffer overrun in callers of EVP_read_pw_string
* Converted more code paths to use CBB/CBS. All handshake messages are
now created by CBB.
* Fixed various memory leaks found by Coverity.
* Simplfied session ticket parsing and handling, inspired by
BoringSSL.
* Modified signature of CRYPTO_mem_leaks_* to return -1. This function
is a no-op in LibreSSL, so this function returns an error to not
indicate the (non-)existence of memory leaks.
* SSL_copy_session_id, PEM_Sign, EVP_EncodeUpdate, BIO_set_cipher,
X509_OBJECT_up_ref_count now return an int for error handling,
matching OpenSSL.
* Converted a number of #defines into proper functions, matching
OpenSSL's ABI.
* Added X509_get0_serialNumber from OpenSSL.
* Removed EVP_PKEY2PKCS8_broken and PKCS8_set_broken, while adding
PKCS8_pkey_add1_attr_by_NID and PKCS8_pkey_get0_attrs, matching
OpenSSL.
* Removed broken pkcs8 formats from openssl(1).
* Converted more functions in public API to use const arguments.
* Stopped handing AES-GCM in ssl_cipher_get_evp, since they use the
EVP_AEAD interface.
* Stopped using composite EVP_CIPHER AEADs.
* Added timing-safe compares for checking results of signature
verification. There are no known attacks, this is just inexpensive
prudence.
* Correctly clear the current cipher state, when changing cipher state.
This fixed an issue where renegotion of cipher suites would fail
when switched from AEAD to non-AEAD or vice-versa.
Issue reported by Bernard Spil.
* Added more cipher tests to appstest.sh, including all TLSv1.2
ciphers.
* Added RSA_meth_get_finish() RSA_meth_set1_name(), and
EVP_CIPHER_CTX_(get|set)_iv() from OpenSSL.
2.8.0 - Bug fixes, security, and compatibility improvements
* Extensive documentation updates and additional API history.
