The Zend Developer Zone has posted both the Zend Weekly Summaries issues #323 and #324.
In #323, there's talk of OpenSSL integration, a CVS server change, and several PHP security discussions (a suggested read).
Issue #324 talks about runtime JIT proposals, debugging overloaded objects, more on PHP security, the release of PHP 5.2.1 RC3, and more "fine grained" control over allow_url_*
