Zend Framework 2.0.0rc4 Released!

VERY Old Content Warning!

We’ve tagged, created and pushed packages, and I’m pleased to announce that the fourth release candidate of ZF2, Zend Framework 2.0.0rc4, is now available!

Release candidates are now happening weekly, and will continue until we feel the code is stable; we anticipate that in the next couple weeks, we should have a stable release.

In the past week, we’ve managed around 50 pull requests, patching primarily bugfixes. Additionally, a patch closing potential XML entity expansion vectors (XEE) was added, and addresses each of Zend\Dom, Zend\Feed, Zend\Soap, and Zend\XmlRpc. If you were building on a version prior to RC4, we highly recommend updating at this time.

Our efforts are now turning primarily to documentation. If you can help us, please do! Enrico has posted a primer on helping with documentation:

as well as a list of documentation tasks:

Please help out!

Below is the full changelog. Take some time to test the release, and to thank all the contributors who have helped get us this far!

UPDATES IN RC4

 the content internally leading to a larger than necessary memory footprint.

 integer; also fixed disconnect() from unsetting property

 schema.table identifiers

 includes updated constants to refer to the parts by

 the processExpression() abstraction for Zend\Db\Sql

 metadata value objects
