Other changes to extensions

The following extensions can no longer be

• PCRE
• Reflection
• SPL

Changes in extension behaviour, and new
features:

• Date and Time – The TZ
  environment variable is no longer used to guess the
  timezone
• cURL – cURL now supports SSH
• Network – dns_check_record() now returns an extra
  “entries” index, containing the TXT elements.
• Hash – The SHA-224 and salsa hash algorithms are
  now supported.
• mbstring – Now supports CP850
  encoding.
• OCI8 – A call to oci_close()
  on a persistent connection, or a variable referencing a persistent
  connection going out of scope, will now roll back any uncommitted
  transaction. To avoid unexpected behavior, explicitly issue a
  commit or roll back as needed. The old behavior can be enabled with
  the INI directive oci8.old_oci_close_semantics. Database Resident Connection Pooling (DRCP) and Fast
  Application Notification (FAN) are now supported.
  Oracle External Authentication is now
  supported (except on Windows). The
  oci_bind_by_name() function now
  supports SQLT_AFC (aka the CHAR datatype).
• OpenSSL – OpenSSL digest and
  cipher functions are now supported. It is also now possible to
  access the internal values of DSA, RSA and DH keys.
• Session – Sessions will no
  longer store session-files in “/tmp” when open_basedir
  restrictions apply, unless “/tmp” is explicitly added to
  the list of allowed paths.
• SOAP Now supports sending user supplied HTTP
  headers.
• MySQLi Now supports persistent
  connections, by prepending the hostname with
  “p:”.
• Image Processing and GD The “JPG
  Support” index returned from gd_info() has
