The PHP team is happy to announce that version 2.0.0 of the mongodb PHP extension is now available on PECL.

Release Highlights

This major release introduces a number of backwards-incompatible changes aimed at simplifying and modernizing the extension's API, cleaning up deprecated functionality, and improving type safety and runtime behavior.

API Cleanups and Removals

• Deprecated constructor options have been removed from the Query and Manager classes.
• The getServer() method and internal Manager references have been removed from APM event classes to streamline event data structures.
• The CursorId class has been removed; Cursor::getId() now returns an Int64 directly.
• Support for passing WriteConcern and ReadPreference objects directly to execute methods has been removed in favor of using readPreference and writeConcern options.
• Legacy exceptions such as WriteException and SSLConnectionException have been removed.

Stronger Typing and Safer APIs

• The UTCDateTime constructor no longer accepts strings or floats. It now only accepts integer millisecond timestamps or instances of DateTimeInterface.
• WriteResult getters will now throw exceptions when called on unacknowledged writes, making error states more explicit.
• The ReadPreference class now requires string mode constants in its constructor. Support for legacy integer constants has been removed.

Deprecation and Legacy Cleanup

• The Serializable interface has been removed from BSON classes, following its deprecation in PHP 8.1.
• All deprecated global BSON functions have been removed; users should use methods on the Document class instead.
• Several configure options (--with-libbson, --with-libmongoc, --enable-system-ciphers, --with-openssl-dir) have been removed to simplify the build process.

New Features and Improvements

• CursorInterface now extends PHP’s native Iterator interface.
• UTCDateTimeInterface introduces a new toDateTimeImmutable() method.
• URI options that expect booleans will now throw if a non-boolean value is provided, preventing silent misconfiguration.

Library Upgrades

• The extension now bundles libmongoc 1.30.3, bringing in the latest stability and feature improvements.

Compatibility updates

• This release requires an upgrade to the mongodb/mongodb Composer library, which introduces compatibility changes for this extension version. Be sure to update your Composer dependencies accordingly.
• PHP 8.1+ Required: The minimum required PHP version is now 8.1, as support for older versions (PHP 7.4 and 8.0) has been dropped.
• MongoDB 4.2+ Required: Future versions of the library will require MongoDB 4.2 or later. MongoDB 4.0 support is deprecated.

A complete list of resolved issues in this release may be found in JIRA.
