Mike Wallner has posted his own roundup of some of the happenings going on in his PHP world behind the scenes.
He talks about the work he's been doing with PHP6 (rewriting an output control layer), with PHP 5.2 (fixes for an Apache issue and the error_get_last function), as well as with pecl/http (new documentation and new updates).
He lists out some of these updates, including improved response preformance, the addition of ArrayAccess to interfaces, and bug fixes on http_parse_cookie, http_build_url, and HttpQueryString failures.
