My slides introducing PHP 5.4.7 from the talk at Guelph PHP user meetup are now available online and can be downloaded at: http://ilia.ws/files/guelph_php54.pdf
Thanks for these slides, Ilia! They're quite illustrative and informative and we were happy to include this information into a digest of the most interesting PHP news and updates: http://www.zfort.com/blog/php-digest-september-29-zfort-group/
