MongoDB HHVM Driver 1.2.0 released

[Derick Rethans]

The PHP team is happy to announce that version 1.2.0 of our new
"mongodb" HHVM extension is now available.

You can download the driver from the attachment to this release
announcement.

**Release Highlights**

This is the first release that supports all features of the MongoDB 3.4
server release, such as Collation support, the Decimal128 BSON type, and
the MongoDB handshake protocol for easier debugging.

It contains a significant amount of internal refactoring to remove our
dependence on libmongoc's private API. This release also upgrades our
libbson and libmongoc dependencies to 1.5.0.

Internal changes aside, we did manage to sneak a few new features into
this release. BSON classes now support PHP serialization, JSON
serialization via json_encode() and PHP's JsonSerializable interface,
and var_export().

The UTCDateTime constructor now defaults to the current time if no
argument is provided and can also accept a DateTimeInterface instance.

The Binary and Javascript types now have __toString() methods that
return their binary data and code strings, respectively. The JavaScript
class also has new getCode() and getScope() methods, which were
curiously absent in previous versions.

A MongoDB\BSON\ObjectID::getTimestamp() helper method has been
introduced, which returns the 4-byte timestamp component of an ObjectID
as an integer. The second $flags parameter to the MongoDB\BSON\Regex
constructor is now optional, defaults to an empty string, and sorts the
flags alphabetically when constructed.

MongoDB\Driver\Query, MongoDB\Driver\BulkWrite::update(), and
MongoDB\Driver\BulkWrite::delete() now accept a "collation" document
option, which can be used to specify a locale-aware string comparison or
sort order (see: Collation in the MongoDB manual for additional
information).

MongoDB\Driver\ReadPreference now supports a "maxStalenessSeconds"
integer option, which can be used with modes other than "primary" to
specify an acceptable replication delay for secondary servers (see:
SERVER-12861). The "maxStalenessSeconds" option may also be used in the
connection URI or options array provided to MongoDB\Driver\Manager to
configure the default read preference.
