| mb_strpos | Support for negative offsets has been added.
| mt_rand | rand has been made an alias of mt_rand.
| mt_rand | mt_rand has been updated to use the fixed, correct, version of the Mersenne Twister algorithm. To fall back to the old behaviour, use mt_srand with MT_RAND_PHP as the second parameter.
| mt_srand | srand has been made an alias of mt_srand.
| mt_srand | mt_rand has been updated to use the fixed, correct, version of the Mersenne Twister algorithm. To fall back to the old behaviour, use mt_srand with MT_RAND_PHP as the second parameter.
| openssl_csr_new | options now also supports curve_name.
| openssl_decrypt | The tag and aad parameters were added.
| openssl_encrypt | The tag, aad and tag_length parameters were added.
| openssl_pkey_new | The curve_name key of the options parameter was added to make it possible to create EC keys based on Elliptic Curve algorithms.
| output_add_rewrite_var | As of PHP 7.1.0, a dedicated output buffer is used, url_rewriter.tags is used solely for output functions and url_rewriter.hosts is available. Prior to PHP 7.1.0, rewrite variables set by output_add_rewrite_var shared an output buffer with transparent session id support (see session.trans_sid_tags).
| output_reset_rewrite_vars | Before PHP 7.1.0, rewrite vars set by output_add_rewrite_var use the same Session module trans sid output buffer. Since PHP 7.1.0, dedicated output buffer is used and output_reset_rewrite_vars only removes rewrite vars defined by output_add_rewrite_var.
| pcntl_signal | As of PHP 7.1.0 the handler callback is given a second argument containing the siginfo of the specific signal. This data is only supplied if the operating system has the siginfo_t structure. If the OS does not implement siginfo_t NULL is supplied.
| pcntl_signal_get_handler | pcntl_signal_get_handler has been added.
| pg_fetch_all | The mode parameter was added.
| pg_last_notice | The mode parameter was added.
| pg_select | The mode parameter was added.
| rand | rand has been made an alias of mt_rand.
| session_start | session_start now returns false and no longer initializes $_SESSION when it failed to start the session.
| shuffle | The internal randomization algorithm has been changed to use the Mersenne Twister Random Number Generator instead of the libc rand function.
| srand | srand has been made an alias of mt_srand.
| str_shuffle | The internal randomization algorithm has been changed to use the Mersenne Twister Random Number Generator instead of the libc rand function.
| stripos | Support for negative offsets has been added.
| strpos | Support for negative offsets has been added.
| substr_count | Support for negative offsets and lengths has been added. length may also be 0 now.
| tempnam | tempnam now emits a notice when falling back to the temp directory of the system.
| unpack | The optional offset has been added.
| unserialize | The allowed_classes element of options is now strictly typed, i.e. if anything other than an array or a bool is given, unserialize returns false and issues an E_WARNING.
| ReflectionType::__toString | ReflectionType::__toString has been deprecated.
| SessionHandler::gc | Prior to this version, the function returned true on success.
| SessionHandlerInterface::gc | Prior to this version, the function returned true on success.
7.0.16 | dns_get_record | Added support for CAA record type.
| fopen | The 'e' option was added.
7.0.15 | get_defined_functions | The exclude_disabled parameter has been added.
| pack | The "e", "E", "g" and "G" codes were added to enable byte order support for float and double.
7.0.11 | iconv_substr | If string is equal to offset characters long, an empty string will be returned. Prior to this version, false was returned in this case.
7.0.10 | imagetypes | IMG_WEBP added.
| SplFileObject::getCsvControl | Added the escape character to the returned array.
| SQLite3::__construct | The filename can now be empty to use a private, temporary on-disk database.
7.0.9 | getenv | The local_only parameter has been added.
7.0.7 | curl_multi_setopt | Introduced CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, CURLMOPT_MAX_HOST_CONNECTIONS, CURLMOPT_MAX_PIPELINE_LENGTH and CURLMOPT_MAX_TOTAL_CONNECTIONS.
| curl_setopt | Introduced CURL_HTTP_VERSION_2, CURL_HTTP_VERSION_2_PRIOR_KNOWLEDGE, CURL_HTTP_VERSION_2TLS, CURL_REDIR_POST_301, CURL_REDIR_POST_302, CURL_REDIR_POST_303, CURL_REDIR_POST_ALL, CURL_VERSION_KERBEROS5, CURL_VERSION_PSL, CURL_VERSION_UNIX_SOCKETS, CURLAUTH_NEGOTIATE, CURLAUTH_NTLM_WB, CURLFTP_CREATE_DIR, CURLFTP_CREATE_DIR_NONE, CURLFTP_CREATE_DIR_RETRY, CURLHEADER_SEPARATE, CURLHEADER_UNIFIED, CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE, CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE, CURLMOPT_MAX_HOST_CONNECTIONS, CURLMOPT_MAX_PIPELINE_LENGTH, CURLMOPT_MAX_TOTAL_CONNECTIONS, CURLOPT_CONNECT_TO, CURLOPT_DEFAULT_PROTOCOL, CURLOPT_DNS_INTERFACE, CURLOPT_DNS_LOCAL_IP4, CURLOPT_DNS_LOCAL_IP6, CURLOPT_EXPECT_100_TIMEOUT_MS, CURLOPT_HEADEROPT, CURLOPT_LOGIN_OPTIONS, CURLOPT_PATH_AS_IS, CURLOPT_PINNEDPUBLICKEY, CURLOPT_PIPEWAIT, CURLOPT_PROXY_SERVICE_NAME, CURLOPT_PROXYHEADER, CURLOPT_SASL_IR, CURLOPT_SERVICE_NAME, CURLOPT_SSL_ENABLE_ALPN, CURLOPT_SSL_ENABLE_NPN, CURLOPT_SSL_FALSESTART, CURLOPT_SSL_VERIFYSTATUS, CURLOPT_STREAM_WEIGHT, CURLOPT_TCP_FASTOPEN, CURLOPT_TFTP_NO_OPTIONS, CURLOPT_UNIX_SOCKET_PATH, CURLOPT_XOAUTH2_BEARER, CURLPROTO_SMB, CURLPROTO_SMBS, CURLPROXY_HTTP_1_0, CURLSSH_AUTH_AGENT and CURLSSLOPT_NO_REVOKE.
