- `CURLCLOSEPOLICY_LEAST_TRAFFIC`

## [OCI8](#book.oci8)

- Support for implicit result sets for Oracle Database 12c has been added via the new `oci_get_implicit_resultset` function.

- Using `oci_execute($s, OCI_NO_AUTO_COMMIT)` for a SELECT no longer unnecessarily initiates an internal ROLLBACK during connection close.

- Added DTrace probes controlled by the `--enable-dtrace` configure option.

- `oci_internal_debug` is now a no-op.

- The `phpinfo` output format for OCI8 has changed.

## [Zip](#book.zip)

A `--with-libzip` configure option has been added to use a system libzip installation. libzip version 0.11 is required, with 0.11.2 or later recommended.

## [MySQLi](#book.mysqli)

A new [mysqli.rollback_on_cached_plink](#ini.mysqli.rollback-on-cached-plink) option was added, which controls the rollback behavior of persistent connections.
