Other changes

• Added support for storing upload progress feedback in session data. Changed session.entropy_file to default to /dev/urandom or /dev/arandom if either is present at compile time.
• E_ALL now includes E_STRICT.
• SNMP now has an OOP API. Functions now return FALSE on every error condition including SNMP-related (no such instance, end of MIB, etc). Thus, in patricular, breaks previous behaviour of get/walk functions returning an empty string on SNMP-related errors. Multi OID get/getnext/set queries are now supported. Dropped UCD-SNMP compatibility code, consider upgrading to net-snmp v5.3+, Net-SNMP v5.4+ is required for Windows version. In sake of adding support for IPv6 DNS name resolution of remote SNMP agent (peer) is done by extension now, not by Net-SNMP library anymore.
• OpenSSL now supports AES.
• CLI SAPI doesn't terminate any more on fatal errors when using interactive mode with readline support.
• Improved parse error messages from parser and warning message of incompatible arguments in function calls.
• $_SERVER['REQUEST_TIME_FLOAT'] has been added to include microsecond precision.
• <?= is now always available regardless of the short_open_tag setting
• Added class member access on instantiation (e.g. (new foo)->bar()) support
• Added new hash algorithms: fnv132, fnv164, joaat
• Chained string offsets - e.g. $a[0][0] where $a is a string - now work.
• Binary number format has been added - e.g. 0b001001101.
• Short array syntax has been added - e.g. $a = [1, 2, 3, 4]; $a = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];
• Class::{expr}() syntax is now supported.
• Function call result array access: foo()[0]
• Closures now support scopes and $this.
• Arrays cast from SimpleXMLElement now always contain all nodes instead of just the first matching node. All SimpleXMLElement children are now always printed when using var_dump(), var_export() and print_r().
• It's now possible to enforce the class' __construct arguments in an abstract constructor in the base class.
