    MongoDB PHP Driver 1.5.0

    It supports all new features for MongoDB 2.6, including:

    • Aggregate can now return a cursor
    • Aggregation pipelines can now be explained
    • Possible to set maxTimeMS for commands and queries
    • Transparent support for the new command-based MongoDB write API
    • New MongoWriteBatch classes (using the new MongoDB write API)
    • Support for MongoDB Enterprise features (e.g. Kerberos, LDAP, X509)
    • Option to tune acceptable server latency for secondary reads (secondaryAcceptableLatencyMS)

    With this release, some driver functionality which was previously documented as deprecated will now formally raise deprecation notices. This includes:

    • Instantiating the Mongo class
    • Calling MongoCursor::slaveOkay()
    • "wtimeout" and "safe" options for MongoCollection write operations
    • Manipulating public properties on core classes (such as $collection->w)

    Note:

    No previously deprecated features have been removed.

    Changes in behaviour:

    • Setting the mongo.native_long INI setting now raises an error on 32-bit platforms, and now defaults to true for 64-bit platforms.

    MongoDB PHP Driver 1.4.0

    The 1.4 series introduced fundemental changes in how connections are created to the MongoDB servers. The driver now utilizes PHP native streams, so all normal PHP stream options apply. Furthermore, an experimental Stream Context Support was added.

    The 1.4.x series also added support for MongoDB 2.4.x.

    The most important improvements however deal with the handling of replica sets, especially nodes that timeout and nodes that are unreachable for various reasons. Besides the improvements to replica set handling, this release addresses issues with read preferences through mongos nodes. It also adds support for SSL enabled connections as well as journal and fsync connection string options.

    MongoDB PHP Driver 1.3.0

    The 1.3 series introduced several major changes to the extension such as completely rewritten connection handling (and removal of the pooling mechanism), support for ReadPreferences and change the default WriteConcerns to be acknowledged by introducing a new class MongoClient which serves as a replacement class for the now deprecated Mongo class.

    The driver now also supports connecting to multiple mongos instances (the Mongo Shard router) for loadbalancing.

    Other enhancements include improved logging for easier connection handling debugging with MongoLog and support for the » Aggregation Framework via the MongoCollection::aggregate() method.

    1.2.0MongoClient::closeBefore version 1.2.0 the driver would not use persistent connections by default, and all connections would be closed as soon as a MongoDB connection went out if scope. Since version 1.2.0 this is no longer the case and it is a bad idea to call close as you might end up overloading the server with connections under high load.
     MongoClient::__constructAdded "username" and "password" options. Removed "persist" option, as all connections are now persistent. It can still be used, but it doesn't affect anything. "persist" If the connection should be persistent. If set, the connection will be persistent. The string representation of the value is used as an ID for the connection, so two instances of MongoClient that are initialized with array("persist" => "foobar") will share the same database connection, whereas an instance initialized with array("persist" => "barbaz") will use a different database connection. The "replicaSet" option now takes a string, not a boolean.
     MongoCollection::ensureIndexAdded "timeout" option.
     MongoCollection::insertAdded "timeout" option.
     MongoCollection::removeAdded "timeout" option.
     MongoCollection::saveAdded "timeout" option.

    1.0.11MongoCollection::ensureIndexThe "safe" option will trigger a primary failover, if necessary. MongoException will be thrown if the index name (either generated or set) is longer than 128 bytes.
     MongoCollection::insertDisconnects on "not master" errors if "safe" is set.
     MongoCollection::removeDisconnects on "not master" errors if "safe" is set.
     MongoCollection::saveDisconnects on "not master" errors if "safe" is set.
     MongoCollection::updateDisconnects on "not master" errors if "safe" is set.
    1.0.10MongoCursor::infoAdded started_iterating field, a boolean indicating if cursor is pre- or post-query.
    1.0.9MongoClient::__constructAdded "replicaSet" option.
     MongoCollection::batchInsertAdded ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option.
     MongoCollection::insertAdded ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option. The return type was changed to be an array containing error information if the "safe" option is used. Otherwise, a boolean is returned as before.
     MongoCollection::removeAdded ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option. The return type was changed to be an array containing error information if the "safe" option is used. Otherwise, a boolean is returned as before.
     MongoCollection::saveAdded "fsync" option.
     MongoCollection::updateAdded ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option. The return type was changed to be an array containing error information if the "safe" option is used. Otherwise, a boolean is returned as before.
    1.0.7MongoCollection::countAdded limit and skip as second and third parameters, respectively.
    1.0.5MongoCollection::batchInsertAdded options parameter.
     MongoCollection::ensureIndexAdded the "name" option to override index name creation.
     MongoCollection::removeChanged second parameter to be an array of options. Pre-1.0.5, the second parameter was a boolean indicating the "safe" option.
     MongoCollection::saveAdded options parameter.
     MongoCollection::updateAdded "safe" option.
    1.0.2MongoClient::__constructChanged constructor to take an array of options. Pre-1.0.2, the constructor took the following parameters: server The server name. connect Optional boolean parameter specifying if the constructor should connect to the database before returning. Defaults to TRUE. persistent If the connection should be persistent. paired If the connection should be paired.
     MongoCollection::ensureIndexChanged options parameter from boolean to array. Pre-1.0.2, the second parameter was an optional boolean value specifying a unique index.
     MongoCollection::insertChanged second parameter to be an array of options. Pre-1.0.2, the second parameter was a boolean indicating the "safe" option.
    1.0.1MongoCollection::insertThrow a MongoCursorException if the "safe" option is set and the insert fails.
     MongoCollection::updateChanged options parameter from boolean to array. Pre-1.0.1, the second parameter was an optional boolean value specifying an upsert.
