* fix broken epoll implementation. (DO NOT USE 5.1.1 with epoll)
* rewrite UDP/TCP/TLS (and DTLS untested) for both select and epoll mode.
complete rewrite of socket (c-ares and UDP/TCP/TLS) in order to accelerate
socket esablishement, and correctly handle socket failure. The change also
help to recover faster after a socket failure and to switch to the next SRV
record available. This last feature was previously broken.
* Fix NAPTR/SRV on windows when CARES is not used. (not advised)
* ACK sent out of transaction with no existing connection may be sent later. (TCP/TLS)
* Upon TLS loss, try to use domain or NAPTR SNI when TLS connection is not initiated by an outgoing transaction.

* add support for authentication using SHA-256 (openssl required)
* only use first supported proposed authentication when same realm is used
* fix: upon UDP errors, like ICMP buffer size may reach abnormal values (avoid useless reallocation)
eXosip2 (5.1.1) - 2020-01-16
* new API:
Generate random string: (low entropy, only hexa)
int eXosip_hexa_generate_random(char *val, int val_size);
Generate random string: (high entropy when compiled with openssl)
int eXosip_byte_generate_random(char *val, int val_size)
* provide more entropy with eXosip_byte_generate_random (with openssl when available).
* fix TLS security issue reported by Alexander Traud regarding hostname validation when using NAPTR/SRV.
* add support for epoll (detected by configured) // becomes the default on linux platforms with autotools
* fix bug #56839: The cnonce should not be static -this is identified as replay attack by some services-.
* fix tcp and tls connection failure detection (accelerate error detection and recovery)
* fix: fixed a crash with DTLS
eXosip2 (5.1.0) - 2019-03-27
* minor API update:
API parameter change: eXosip_call_build_ack/eXosip_call_send_ack API to use tid instead of did as parameter.
* new API: add an API to insert one extra header in BYE:
int eXosip_call_terminate_with_header(struct eXosip_t *excontext, int cid, int did, const char *header_name, const char *header_value);
void eXosip_dnsutils_release(struct osip_naptr *naptr_record); required after usage of eXosip_dnsutils_naptr.
* new OPTION:
EXOSIP_OPT_SET_SESSIONTIMERS_FORCE option to force session timer to be used when remote side does not support it.
* structure change:
new param in eXosip_tls_credentials_t for pinning: "public_key_pinned". A file with the expected public key of server.
If you use eXosip_tls_ctx_t/eXosip_tls_credentials_t/EXOSIP_OPT_SET_TLS_CERTIFICATES_INFO, you need to recompile.
* fix processing response out of transaction. (avoid incorrect logs and extra work)
* fix https://savannah.nongnu.org/bugs/?54628 where ACK was only retransmitted for initial outgoing INVITE.
fix: retransmit ACK for both initial INVITE and re-INVITE.
fix: retransmit ACK for 2xx from forking (with a BYE) even if call does not exist.
ACK for "old transaction" within the established dialog won't be retransmitted because the parameter only hold the latest ACK.
* fix bug report: https://savannah.nongnu.org/bugs/index.php?54624
another patch to fix more issue related to cseq & PRACK.
The newer code better handle forking use-case with PRACK.
The newer code better handle several 1xx from same user.
* fix bug report: https://savannah.nongnu.org/bugs/index.php?54624 cseq wasn't increasing after a PRACK.

* improve reliability for naptr/srv lookup (but still a short time).
* fix/improve _eXosip_mark_registration_expired: it was working correctly only if registration had previously failed.
* fix: attach call/dialog to CANCEL transaction (so EXOSIP_CALL_MESSAGE_ANSWERED will be received instead of EXOSIP_MESSAGE_ANSWERED).
* windows: fix DnsQuery to use UTF8 even if compiled without UNICODE (not applicable if you use c-ares).
* windows: add ENUM capability and improve NAPTR/SRV record (not applicable if you use c-ares).
* windows: you should use c-ares AND you should compile with UNICODE. (much better).
* add ability to define a dnsserver when doing NAPTR and SRV record (c-ares only).
* format of domain string for "eXosip_dnsutils_naptr" is "domain.com!+AUS|IP_DNSSERVER".

improvements to retreive (and release) it via eXosip_dnsutils_naptr and eXosip_dnsutils_release APIs.
* TLS improvments: simplify client and server config, add ECDH cipher suite if missing,
password for private key is optional, add support for public key pinning.

* handle incoming UPDATE from alternative dialogs in early dialog mode.
* fix to reject any NOTIFY without established dialog coming later than 64 seconds after initial SUBSCRIBE.
* After a NAPTR query, some DNS server returns SUCCESS without NAPTR answers. In such use-case, fallback to manual SRV records.
* add SOCK_CLOEXEC option to sockets // add missing SO_KEEPALIVE options on TLS socket.
* EXOSIP_OPT_ENABLE_IPV6 now support 0(ipv4 only), 1(ipv6 only) and 2(ipv4 OR ipv6).
With option 2, choice is made based on DNS and the stack can fallback between IPv4 and IPv6.
* fix possible memory leak when using wrong tid for eXosip_insubscription_send_answer.
* fix possible memory leak upon allocation error.
* fix leak upon syntax error in parameters provided for PUBLISH.
