...
Removed hardware support:
ST-506 disks are no longer supported.
...
pledge(2) support integrated:
tame(2) system call renamed to pledge(2).
453 out of 707 base system binaries adapted to use pledge.
14 ports adapted to use pledge (some decompression tools, mutt, some pdf tools, chromium/iridium, and the i3 window manager).
Several bugs exposed by pledge(2) have been corrected, for example in bgpd(8), iked(8), ldapd(8), ntpd(8), and syslogd(8),
Several misguided "features" have been removed, such as support for HOSTALIASES from the resolver, support for "lookup yp" in /etc/resolv.conf, setuid-preserving code in binutils tools or ed-style diffs via proc/exec in patch(1).
A somewhat intensive audit of userland program so that they could be properly annotated with pledge(2) was done, resulting in some design changes such as in rdate(1), sndiod(8) or the introduction of SOCK_DNS socket(2) flag that makes an SS_DNS tagged socket conceptually different from a plain socket.
It also has been used to constrain programs to a more limited POSIX subset, such as some binutils tools that handle untrusted data (strings(1), objdump(1), ...), or the RSA-privsep process in smtpd(1).
Generic network stack improvements:
Remove support for obsolete IPv6 socket options.
New etherip(4) pseudo-device for tunnelling Ethernet frames across IP[46] networks using RFC 3378 EtherIP encapsulation.
New pair(4) pseudo-device for ...
...
Installer improvements:
Inappropriate user choices from a list of options are more reliably rejected.
Installing to a disk partitioned with a GPT is now supported (amd64 only).
When initializing a GPT the required EFI System partition is automatically created.
When installing to a GPT disk installboot(8) now formats the EFI System partition, creates the appropriate directory structure and copies the required UEFI boot files into place.
...
Routing daemons and other userland network improvements:
dhclient(8) now supports multiple domain names provided via DHCP option 15 (Domain Name).
dhclient(8) now supports search domains provided via DHCP option 119 (Domain Search).
dhclient(8) no longer continually checks for a change to the routing domain of the interface it controls. It now relies on the appropriate routing socket messages.
dhclient(8) now issues DHCP DECLINE responses to lease offers found to be inadequate, and restarts the DISCOVER/RENEW process rather than waiting indefinitely for a better lease to appear.
dhclient(8) no longer exits if a desired route cannot be added. It now just reports the fact.
dhclient(8) now takes a much more careful approach to received packets to ensure only received data is used to process the packet. Packets with incorrect length information or lacking appropriate header information are now dropped.
dhclient(8) again disables pending timeouts if the interface link is lost, preventing endless retries at obtaining a lease.
dhclient(8) was pledged.
dhcpd(8) again properly utilizes default-lease-time, max-lease-time and bootp-lease-time options.
dhcpd(8) was pledged.
...
Security improvements:
...
Support for looking up hosts via YP has been removed from libc. The 'yp' lookup method in resolv.conf is no longer available.
Support for the HOSTALIASES environment variable has been removed from libc.
Assorted improvements:
doas(1) is a little friendlier to use.
Updated flex(1).
Updated and improved less(1).
pdisk(8) was largely rewritten and pledged.
Renaming files in the root directory of a MSDOS filesystem was fixed.
Many obsolete disktab(5) attributes and entries were removed.
softraid(4) volumes now correctly look for the disklabel in the first OpenBSD disk partition, not the last.
softraid(4) volumes can now be partitioned with a GPT.
fdisk(8) now creates a default GPT as well as the protective MBR when the '-g' flag is used.
fdisk(8) now has a '-b' flag that specifies the size of the EFI System partition to create.
fdisk(8) now has a '-v' flag that causes a verbose display of both MBR and GPT information.
fdisk(8) now provides full interactive GPT editing.
fdisk(8) was pledged.
Disks with sector sizes other than 512 bytes can now be partitioned with a GPT.
The GPT kernel option was removed and GPT support is part of all GENERIC and GENERIC derived kernels.
Many improvements were made to the GPT kernel support to ensure safe and reliable operation of GPT and MBR processing.
disklabel(8) no longer supports boot code installation, with the -B and -b flags being removed. The associated fields in the disklabel were also removed. These functions are now all performed by installboot(8).
PowerPC converted to secure-PLT ABI variant.
Perform lazy binding updates in ld.so(1) using kbind(2) to improve security and reduce overhead in threaded processes.
Over 100 internal or obsolete interfaces have been deleted or are no longer exported by libc, reducing symbol conflicts and process size.
libc now uses local references for most of its own functions to avoid symbol overriding, improve standards compliance, increase speed, and reduce dynamic linking overhead.
Handle intra-thread kills via new thrkill(2) system call to tighten pledge(2) restrictions and improve pthread_kill(3) and pthread_cancel(3) compliance.
Added getpwnam_shadow(3) and getpwuid_shadow(3) to permit tighter pledge(2) restrictions.
Added support to ktrace(1) the arguments to execve(2) and pledge(2). Removed support for tracing context switch points. kevent structures are now dumped.
...
OpenBSD httpd(8):
...
OpenSMTPD 5.9.1
Security:
Both smtpd(8) and smtpctl(8) have been pledged.
The offline enqueue mode of smtpctl(8) has been redesigned to remove the need for a publicly writable directory which was a vector of multiple attacks in the Qualys Security audit.
The following improvements were brought in this release:
Experimental support for filters API is now available with several filters available in ports.
Add Message-Id header if necessary.
Removed the kick mechanism which was misbehaving.
Increased the length of acceptable headers lines.
Assume messages are 8-bit bytes by default.
OpenSSH 7.2
Security:
Qualys Security identified vulnerabilities in the ssh(1) client experimental support for resuming SSH-connections (roaming). In the default configuration, this could potentially leak client keys to a hostile server. The authentication of the server host key prevents exploitation by a man-in-the-middle, so this information leak is restricted to connections to malicious or compromised servers. This feature has been disabled in the ssh(1) client, and it has been removed from the source tree. The matching server code has never been shipped.
sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication.
Fix an out of-bound read access in the packet handling code.
Further use of explicit_bzero(3) has been added in various buffer handling code paths to guard against compilers aggressively doing dead-store removal.
ssh(1), sshd(8): remove unfinished and unused roaming code.
ssh(1): eliminate fallback from untrusted X11 forwarding to trusted forwarding when the X server disables the SECURITY extension.
ssh(1), sshd(8): increase the minimum modulus size supported for diffie-hellman-group-exchange to 2048 bits.
Potentially-incompatible changes:
This release disables a number of legacy cryptographic algorithms by default in ssh(1):
Several ciphers: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
MD5-based and truncated HMAC algorithms.
New/changed features:
all: add support for RSA signatures using SHA-256/512 hash algorithms based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
ssh(1): Add an AddKeysToAgent client option which can be set to yes, no, ask, or confirm, and defaults to no. When enabled, a private key that is used during authentication will be added to ssh-agent(1) if it is running (with confirmation enabled if set to confirm).
sshd(8): add a new authorized_keys option restrict that includes all current and future key restrictions (no-*-forwarding, etc.). Also add permissive versions of the existing restrictions, e.g. no-pty -> pty. This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future.
ssh(1): add ssh_config(5) CertificateFile option to explicitly list certificates. (bz#2436)
ssh-keygen(1): allow ssh-keygen(1) to change the key comment for all supported formats.
ssh-keygen(1): allow fingerprinting from standard input, e.g. "ssh-keygen -lf -".
ssh-keygen(1): allow fingerprinting multiple public keys in a file, e.g. ssh-keygen -lf ~/.ssh/authorized_keys. (bz#1319)
sshd(8): support none as an argument for sshd_config(5) Foreground and ChrootDirectory. Useful inside Match blocks to override a global default. (bz#2486)
ssh-keygen(1): support multiple certificates (one per line) and reading from standard input (using "-f -") for ssh-keygen -L.
ssh-keyscan(1): add ssh-keyscan -c ... flag to allow fetching certificates instead of plain keys.
ssh(1): better handle anchored FQDNs (e.g. cvs.openbsd.org.) in hostname canonicalisation - treat them as already canonical and trailing '.' before matching ssh_config(5).
The following significant bugs have been fixed in this release:
ssh(1), sshd(8): add compatibility workarounds for FuTTY.
ssh(1), sshd(8): refine compatibility workarounds for WinSCP.
Fix a number of memory faults (double-free, free of uninitialised memory, etc) in ssh(1) and ssh-keygen(1).
Correctly interpret the first_kex_follows option during the initial key exchange.
sftp(1): existing destination directories should not terminate recursive uploads (regression in openssh 6.8). (bz#2528)
ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED replies to unexpected messages during key exchange. (bz#2949)
ssh(1): refuse attempts to set ConnectionAttempts=0, which does not make sense and would cause ssh to print an uninitialised stack variable. (bz#2500)
ssh(1): fix errors when attempting to connect to scoped IPv6 addresses with hostname canonicalisation enabled.
sshd_config(5): list a couple more options usable in Match blocks. (bz#2489)
sshd(8): fix PubkeyAcceptedKeyTypes +... inside a Match block.
ssh(1): expand tilde characters in filenames passed to -i options before checking whether or not the identity file exists. Avoids confusion for cases where shell doesn't expand (e.g. -i ~/file vs. -i~/file). (bz#2481)
ssh(1): do not prepend "exec" to the shell command run by Match exec in a config file, which could cause some commands to fail in certain environments. (bz#2471)
ssh-keyscan(1): fix output for multiple hosts/addrs on one line when host hashing or a non standard port is in use. (bz#2479)
sshd(8): skip "Could not chdir to home directory" message when ChrootDirectory is active. (bz#2485)
ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump.
sshd(8): avoid changing TunnelForwarding device flags if they are already what is needed; makes it possible to use tun(4)/ tap(4) networking as non-root user if device permissions and interface flags are pre-established.
ssh(1), sshd(8): RekeyLimits could be exceeded by one packet. (bz#2521)
ssh(1): fix multiplexing master failure to notice client exit.
ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that present empty key IDs. (bz#1773)
sshd(8): avoid printf(3) of NULL argument. (bz#2535)
ssh(1), sshd(8): allow RekeyLimits larger than 4GB. (bz#2521)
ssh-agent(1), sshd(8): fix several bugs in (unused) KRL signature support.
ssh(1), sshd(8): fix connections with peers that use the key exchange guess feature of the protocol. (bz#2515)
sshd(8): include remote port number in log messages. (bz#2503)
ssh(1): don't try to load SSHv1 private key when compiled without SSHv1 support. (bz#2505)
ssh-agent(1), ssh(1): fix incorrect error messages during key loading and signing errors. (bz#2507)
ssh-keygen(1): don't leave empty temporary files when performing known_hosts file edits when known_hosts doesn't exist.
sshd(8): correct packet format for tcpip-forward replies for requests that don't allocate a port. (bz#2509)
ssh(1), sshd(8): fix possible hang on closed output. (bz#2469)
ssh(1): expand %i in ControlPath to UID. (bz#2449)
ssh(1), sshd(8): fix return type of openssh_RSA_verify. (bz#2460)
ssh(1), sshd(8): fix some option parsing memory leaks. (bz#2182)
ssh(1): add a some debug output before DNS resolution; it's a place where ssh could previously silently stall in cases of unresponsive DNS servers. (bz#2433)
ssh(1): remove spurious newline in visual hostkey. (bz#2686)
ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+...
ssh(1): fix expansion of HostkeyAlgorithms=+...
LibreSSL 2.3.2
User-visible features:
This release corrects the handling of ClientHello messages that do not include TLS extensions, resulting in such handshakes being aborted.
When loading a DSA key from a raw (without DH parameters) ASN.1 serialization, perform some consistency checks on its `p' and `q' values, and return an error if the checks failed.
Fixed a bug in ECDH_compute_key that can lead to silent truncation of the result key without error. A coding error could cause software to use much shorter keys than intended.
Removed support for DTLS_BAD_VER. Pre-DTLSv1 implementations are no longer supported.
The engine command and parameters are removed from openssl(1). Previous releases removed dynamic and built-in engine support already.
SHA-0 is removed, which was withdrawn shortly after publication twenty years ago.
Added Certplus CA root certificate to the default cert.pem file.
Fixed a leak in SSL_new(3) in the error path.
Fixed a memory leak and out-of-bounds access in OBJ_obj2txt(3).
Fixed an up-to 7 byte overflow in RC4 when len is not a multiple of sizeof(RC4_CHUNK).
Added EVP_aead_chacha20_poly1305(3) which matches the AEAD construction introduced in RFC 7539, which is different than that already used in TLS with EVP_aead_chacha20_poly1305(3).
More man pages converted from pod to mdoc(7) format.
Added COMODO RSA Certification Authority and QuoVadis root certificates to cert.pem.
Removed Remhve "C=US, O=VeriSign, Inc., OU=Class 3 Public Primary Certification Authority" (serial 3c:91:31:cb:1f:f6:d0:1b:0e:9a:b8:d0:44:bf:12:be) root certificate from cert.pem.
Fixed incorrect TLS certificate loading by nc(1).
The following CVEs had been fixed:
CVE-2015-3194—NULL pointer dereference in client side certificate validation.
CVE-2015-3195—memory leak in PKCS7, not reachable from TLS/SSL.
Note: The following OpenSSL CVEs did not apply to LibreSSL:
CVE-2015-3193—carry propagating bug in the x86_64 Montgomery squaring procedure.
CVE-2015-3196—double free race condition of the identify hint data.
Code improvements:
Added install target for cmake builds.
Updated pkgconfig files to correctly report the release version number, not the individual library ABI version numbers.
SSLv3 is now permanently removed from the tree.
The libtls API is changed from the 2.2.x series:
The tls_read(3) and tls_write(3) functions now work better with external event libraries.
Client-side verification is now supported, with the client supplying the certificate to the server.
Also, when using tls_connect_fds(3), tls_connect_socket(3) or tls_accept_fds(3), libtls no longer implicitly closes the passed in sockets. The caller is responsible for closing them in this case.
New interface OPENSSL_cpu_caps is provided that does not allow software to inadvertently modify cpu capability flags. OPENSSL_ia32cap and OPENSSL_ia32cap_loc are removed.
The out_len argument of AEAD changed from ssize_t to size_t.
Deduplicated DTLS code, sharing bugfixes and improvements with TLS.
Converted nc(1) to use libtls for client and server operations; it is included in the libressl-portable distribution as an example of how to use the libtls library. This is intended to be a simpler and more robust replacement for openssl s_client and openssl s_server for day-to-day operations.
ASN.1 cleanups and RFC5280 compliance fixes.
Time representations switched from unsigned long to time_t. LibreSSL now checks if the host OS supports 64-bit time_t.
Support always extracting the peer cipher and version with libtls.
Added ability to check certificate validity times with libtls, tls_peer_cert_notbefore(3) and tls_peer_cert_notafter(3).
Changed tls_connect_servername(3) to use the first address that resolves with getaddrinfo(3).
Remove broken conditional EVP_CHECK_DES_KEY code (non-functional since initial commit in 2004).
Reject too small bits value in BN_generate_prime_ex(3), so that it does not risk becoming negative in probable_prime_dh_safe().
Changed format of LIBRESSL_VERSION_NUMBER to match that of OPENSSL_VERSION_NUMBER.
Avoid a potential undefined C99+ behavior due to shift overflow in AES_decrypt.
Deprecated the SSL_OP_SINGLE_DH_USE flag.

Qualys Security identified vulnerabilities in the ssh(1) client experimental support for resuming SSH-connections (roaming). In the default configuration, this could potentially leak client keys to a hostile server. The authentication of the server host key prevents exploitation by a man-in-the-middle, so this information leak is restricted to connections to malicious or compromised servers. This feature has been disabled in the ssh(1) client, and it has been removed from the source tree. The matching server code has never been shipped.
sshd(8): OpenSSH 7.0 contained a logic error in PermitRootLogin=prohibit-password/without-password that could, depending on compile-time configuration, permit password authentication to root while preventing other forms of authentication.
Fix an out of-bound read access in the packet handling code.
Further use of explicit_bzero(3) has been added in various buffer handling code paths to guard against compilers aggressively doing dead-store removal.
ssh(1), sshd(8): remove unfinished and unused roaming code.
ssh(1): eliminate fallback from untrusted X11 forwarding to trusted forwarding when the X server disables the SECURITY extension.
ssh(1), sshd(8): increase the minimum modulus size supported for diffie-hellman-group-exchange to 2048 bits.
Potentially-incompatible changes:
This release disables a number of legacy cryptographic algorithms by default in ssh(1):
Several ciphers: blowfish-cbc, cast128-cbc, all arcfour variants and the rijndael-cbc aliases for AES.
MD5-based and truncated HMAC algorithms.
New/changed features:
all: add support for RSA signatures using SHA-256/512 hash algorithms based on draft-rsa-dsa-sha2-256-03.txt and draft-ssh-ext-info-04.txt.
ssh(1): Add an AddKeysToAgent client option which can be set to yes, no, ask, or confirm, and defaults to no. When enabled, a private key that is used during authentication will be added to ssh-agent(1) if it is running (with confirmation enabled if set to confirm).
sshd(8): add a new authorized_keys option restrict that includes all current and future key restrictions (no-*-forwarding, etc.). Also add permissive versions of the existing restrictions, e.g. no-pty -> pty. This simplifies the task of setting up restricted keys and ensures they are maximally-restricted, regardless of any permissions we might implement in the future.
ssh(1): add ssh_config(5) CertificateFile option to explicitly list certificates. (bz#2436)
ssh-keygen(1): allow ssh-keygen(1) to change the key comment for all supported formats.
ssh-keygen(1): allow fingerprinting from standard input, e.g. "ssh-keygen -lf -".
ssh-keygen(1): allow fingerprinting multiple public keys in a file, e.g. ssh-keygen -lf ~/.ssh/authorized_keys. (bz#1319)
sshd(8): support none as an argument for sshd_config(5) Foreground and ChrootDirectory. Useful inside Match blocks to override a global default. (bz#2486)
ssh-keygen(1): support multiple certificates (one per line) and reading from standard input (using "-f -") for ssh-keygen -L.
ssh-keyscan(1): add ssh-keyscan -c ... flag to allow fetching certificates instead of plain keys.
ssh(1): better handle anchored FQDNs (e.g. cvs.openbsd.org.) in hostname canonicalisation - treat them as already canonical and trailing '.' before matching ssh_config(5).
The following significant bugs have been fixed in this release:
ssh(1), sshd(8): add compatibility workarounds for FuTTY.
ssh(1), sshd(8): refine compatibility workarounds for WinSCP.
Fix a number of memory faults (double-free, free of uninitialised memory, etc) in ssh(1) and ssh-keygen(1).
Correctly interpret the first_kex_follows option during the initial key exchange.
sftp(1): existing destination directories should not terminate recursive uploads (regression in openssh 6.8). (bz#2528)
ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED replies to unexpected messages during key exchange. (bz#2949)
ssh(1): refuse attempts to set ConnectionAttempts=0, which does not make sense and would cause ssh to print an uninitialised stack variable. (bz#2500)
ssh(1): fix errors when attempting to connect to scoped IPv6 addresses with hostname canonicalisation enabled.
sshd_config(5): list a couple more options usable in Match blocks. (bz#2489)
sshd(8): fix PubkeyAcceptedKeyTypes +... inside a Match block.
ssh(1): expand tilde characters in filenames passed to -i options before checking whether or not the identity file exists. Avoids confusion for cases where shell doesn't expand (e.g. -i ~/file vs. -i~/file). (bz#2481)
ssh(1): do not prepend "exec" to the shell command run by Match exec in a config file, which could cause some commands to fail in certain environments. (bz#2471)
ssh-keyscan(1): fix output for multiple hosts/addrs on one line when host hashing or a non standard port is in use. (bz#2479)
sshd(8): skip "Could not chdir to home directory" message when ChrootDirectory is active. (bz#2485)
ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump.
sshd(8): avoid changing TunnelForwarding device flags if they are already what is needed; makes it possible to use tun(4)/ tap(4) networking as non-root user if device permissions and interface flags are pre-established.
ssh(1), sshd(8): RekeyLimits could be exceeded by one packet. (bz#2521)
ssh(1): fix multiplexing master failure to notice client exit.
ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that present empty key IDs. (bz#1773)
sshd(8): avoid printf(3) of NULL argument. (bz#2535)
ssh(1), sshd(8): allow RekeyLimits larger than 4GB. (bz#2521)
ssh-agent(1), sshd(8): fix several bugs in (unused) KRL signature support.
ssh(1), sshd(8): fix connections with peers that use the key exchange guess feature of the protocol. (bz#2515)
sshd(8): include remote port number in log messages. (bz#2503)
ssh(1): don't try to load SSHv1 private key when compiled without SSHv1 support. (bz#2505)
ssh-agent(1), ssh(1): fix incorrect error messages during key loading and signing errors. (bz#2507)
ssh-keygen(1): don't leave empty temporary files when performing known_hosts file edits when known_hosts doesn't exist.
sshd(8): correct packet format for tcpip-forward replies for requests that don't allocate a port. (bz#2509)
ssh(1), sshd(8): fix possible hang on closed output. (bz#2469)
ssh(1): expand %i in ControlPath to UID. (bz#2449)
ssh(1), sshd(8): fix return type of openssh_RSA_verify. (bz#2460)
ssh(1), sshd(8): fix some option parsing memory leaks. (bz#2182)
ssh(1): add a some debug output before DNS resolution; it's a place where ssh could previously silently stall in cases of unresponsive DNS servers. (bz#2433)
ssh(1): remove spurious newline in visual hostkey. (bz#2686)
ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+...
ssh(1): fix expansion of HostkeyAlgorithms=+...
LibreSSL 2.3.2
User-visible features:
This release corrects the handling of ClientHello messages that do not include TLS extensions, resulting in such handshakes being aborted.
When loading a DSA key from a raw (without DH parameters) ASN.1 serialization, perform some consistency checks on its `p' and `q' values, and return an error if the checks failed.
Fixed a bug in ECDH_compute_key that can lead to silent truncation of the result key without error. A coding error could cause software to use much shorter keys than intended.
Removed support for DTLS_BAD_VER. Pre-DTLSv1 implementations are no longer supported.
The engine command and parameters are removed from openssl(1). Previous releases removed dynamic and built-in engine support already.
SHA-0 is removed, which was withdrawn shortly after publication twenty years ago.
Added Certplus CA root certificate to the default cert.pem file.
Fixed a leak in SSL_new(3) in the error path.
Fixed a memory leak and out-of-bounds access in OBJ_obj2txt(3).
Fixed an up-to 7 byte overflow in RC4 when len is not a multiple of sizeof(RC4_CHUNK).
Added EVP_aead_chacha20_poly1305(3) which matches the AEAD construction introduced in RFC 7539, which is different than that already used in TLS with EVP_aead_chacha20_poly1305(3).
More man pages converted from pod to mdoc(7) format.
Added COMODO RSA Certification Authority and QuoVadis root certificates to cert.pem.
Removed Remhve "C=US, O=VeriSign, Inc., OU=Class 3 Public Primary Certification Authority" (serial 3c:91:31:cb:1f:f6:d0:1b:0e:9a:b8:d0:44:bf:12:be) root certificate from cert.pem.
Fixed incorrect TLS certificate loading by nc(1).
The following CVEs had been fixed:
CVE-2015-3194—NULL pointer dereference in client side certificate validation.
CVE-2015-3195—memory leak in PKCS7, not reachable from TLS/SSL.
Note: The following OpenSSL CVEs did not apply to LibreSSL:
CVE-2015-3193—carry propagating bug in the x86_64 Montgomery squaring procedure.
CVE-2015-3196—double free race condition of the identify hint data.
Code improvements:
Added install target for cmake builds.
Updated pkgconfig files to correctly report the release version number, not the individual library ABI version numbers.
SSLv3 is now permanently removed from the tree.
The libtls API is changed from the 2.2.x series:
The tls_read(3) and tls_write(3) functions now work better with external event libraries.
Client-side verification is now supported, with the client supplying the certificate to the server.
Also, when using tls_connect_fds(3), tls_connect_socket(3) or tls_accept_fds(3), libtls no longer implicitly closes the passed in sockets. The caller is responsible for closing them in this case.
New interface OPENSSL_cpu_caps is provided that does not allow software to inadvertently modify cpu capability flags. OPENSSL_ia32cap and OPENSSL_ia32cap_loc are removed.
The out_len argument of AEAD changed from ssize_t to size_t.
Deduplicated DTLS code, sharing bugfixes and improvements with TLS.
Converted nc(1) to use libtls for client and server operations; it is included in the libressl-portable distribution as an example of how to use the libtls library. This is intended to be a simpler and more robust replacement for openssl s_client and openssl s_server for day-to-day operations.
ASN.1 cleanups and RFC5280 compliance fixes.
Time representations switched from unsigned long to time_t. LibreSSL now checks if the host OS supports 64-bit time_t.
Support always extracting the peer cipher and version with libtls.
Added ability to check certificate validity times with libtls, tls_peer_cert_notbefore(3) and tls_peer_cert_notafter(3).
Changed tls_connect_servername(3) to use the first address that resolves with getaddrinfo(3).
Remove broken conditional EVP_CHECK_DES_KEY code (non-functional since initial commit in 2004).
Reject too small bits value in BN_generate_prime_ex(3), so that it does not risk becoming negative in probable_prime_dh_safe().
Changed format of LIBRESSL_VERSION_NUMBER to match that of OPENSSL_VERSION_NUMBER.
Avoid a potential undefined C99+ behavior due to shift overflow in AES_decrypt.
Deprecated the SSL_OP_SINGLE_DH_USE flag.
