The following changes have been made to classes/functions/methods of this extension.
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.
Following is a list of all improvements to existing methods since their inception.
| Version | Function | Description |
|---|---|---|
| 1.3.0 | MongoClient::close | The connection parameter to this function was added in 1.3.0. Before that, only the write connection would be closed by this method. |
| MongoClient::__construct | Added the "readPreference", "readPreferenceTags", "w" and "wTimeout" options. | |
| MongoCollection::ensureIndex | The options parameter no longer accepts a boolean to signify a unique index. Instead, this now has to be done with array('unique' => true). | |
| MongoCollection::insert | The options parameter no longer accepts a boolean to signify a acknowledged write. Instead, this now has to be done with array('w' => 1) (The default behaviour of MongoClient). | |
| MongoCollection::remove | The options parameter no longer accepts a boolean to signify "justOne". Instead, this now has to be done with array('justOne' => true). | |
| MongoCollection::update | The options parameter no longer accepts a boolean to signify an upsert. Instead, this now has to be done with array('upsert' => true). | |
| MongoDB::listCollections | Added the includeSystemCollections parameter. | |
| MongoGridFSCursor::key | The document's _id is returned as a string value, since the key should be unique. Pre-1.3.0, filename was returned. | |
| 1.2.11 | Mongo::getPoolSize | Emits E_DEPRECATED when used. |
| Mongo::getSlave | Emits E_DEPRECATED when used. | |
| Mongo::getSlaveOkay | Emits E_DEPRECATED when used. | |
| Mongo::poolDebug | Emits E_DEPRECATED when used. | |
| Mongo::setSlaveOkay | Emits E_DEPRECATED when used. | |
| Mongo::switchSlave | Emits E_DEPRECATED when used. | |
| MongoBinData::__construct | Emits E_DEPRECATED when the second argument is not used. The default value for type may change in the near future. | |
| MongoCollection::ensureIndex | Emits E_DEPRECATED when options is scalar. | |
| MongoCollection::getSlaveOkay | Emits E_DEPRECATED when used. | |
| MongoCollection::group | Emits E_DEPRECATED when options is scalar. | |
| MongoCollection::remove | Emits E_DEPRECATED when options is scalar. | |
| MongoCollection::setSlaveOkay | Emits E_DEPRECATED when used. | |
| MongoCollection::update | Emits E_DEPRECATED when options is scalar. | |
| MongoCursor::doQuery | Emits E_DEPRECATED when used. | |
| MongoDB::authenticate | Emits E_DEPRECATED when used. Please pass in the authentication details to the constructor. | |
| MongoDB::forceError | Emits E_DEPRECATED when used. | |
| MongoDB::getSlaveOkay | Emits E_DEPRECATED when used. | |
| MongoDB::prevError | Emits E_DEPRECATED when used. | |
| MongoDB::resetError | Emits E_DEPRECATED when used. | |
| MongoDB::setSlaveOkay | Emits E_DEPRECATED when used. | |
| MongoPool::getSize | Emits E_DEPRECATED when used. | |
| MongoPool::info | Emits E_DEPRECATED when used. | |
| MongoPool::setSize | Emits E_DEPRECATED when used. | |
| 1.2.10 | MongoClient::getHosts | Support for non-replicasets was added. The returned array elements now also include the hostname and port. |
| 1.2.7 | MongoCollection::batchInsert | Added "continueOnError" option. |
| 1.2.5 | MongoGridFS::storeUpload | Changed second parameter to an array of metadata. Pre-1.2.5, the second parameter was an optional string overriding the filename. |
| 1.2.0 | MongoClient::close | Before 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::__construct | Added the "username" and "password" options. Removed the "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::ensureIndex | Added "timeout" option. | |
| MongoCollection::insert | Added "timeout" option. | |
| MongoCollection::remove | Added "timeout" option. | |
| MongoCollection::save | Added "timeout" option. | |
| MongoCollection::update | Added "timeout" option. | |
| MongoDB::command | Added options parameter with a single option: "timeout". | |
| 1.1.0 | MongoCursor::info | Added a number of other fields, including id (the cursor id), at (the driver's counter of which document is current), numReturned (the number returned by the server in the current batch), and server (which server the query was sent to—useful in conjunction with . |
| 1.0.11 | MongoCollection::ensureIndex | The "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::insert | Disconnects on "not master" errors if "safe" is set. | |
| MongoCollection::remove | Disconnects on "not master" errors if "safe" is set. | |
| MongoCollection::save | Disconnects on "not master" errors if "safe" is set. | |
| MongoCollection::update | Disconnects on "not master" errors if "safe" is set. | |
| 1.0.10 | MongoCursor::info | Added started_iterating field, a boolean indicating if cursor is pre- or post-query. |
| 1.0.9 | MongoClient::__construct | Added the "replicaSet" option. |
| MongoCollection::batchInsert | Added ability to pass integers to the "safe" option, which previously only accepted booleans. Added "fsync" option. | |
| MongoCollection::insert | Added 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::remove | Added 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::update | Added 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. | |
| 1.0.7 | MongoCollection::count | Added limit and skip parameters. |
| 1.0.5 | MongoCollection::batchInsert | Added options parameter. |
| MongoCollection::insert | Changed second parameter to be an array of options. Pre-1.0.5, the second parameter was a boolean indicating the "safe" option. | |
| MongoCollection::remove | Changed second parameter to be an array of options. Pre-1.0.5, the second parameter was a boolean indicating the "safe" option. | |
| MongoCollection::save | Added options parameter. | |
| MongoCollection::update | Added "safe" option. | |
| 1.0.2 | MongoClient::__construct | Changed 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::ensureIndex | Changed options parameter from boolean to array. Pre-1.0.2, the second parameter was an optional boolean value specifying a unique index. | |
| 1.0.1 | MongoCollection::insert | Throw a MongoCursorException if the "safe" option is set and the insert fails. |
| MongoCollection::update | Changed options parameter from boolean to array. Pre-1.0.1, the second parameter was an optional boolean value specifying an upsert. |
