XML output of PHP bugs

Hi there webmasters :) Since part of my job is to regularly check on latest security problems in php I need some permanent solution on following bug reports. Since they change status etc its hard for me to follow. Is there any XML feed I can use to make my own history of how bug status change etc. If not I will have to parse the html directly from the web... Any suggestions on this issue... Thank you in advance for spending time reading this letter. P.S. I guess the problem with not having XML feed is because of the huge trafic that will be genarated. But info on just the summary of bugs is ok...even without its content. Once I know the history of the bug and the link to it I could visit the content withouth a problem.
