The project kicked off mid-month with the merge of patches that enable PSR-3 based logging by MediaWiki. These changes are being tested in beta and will begin to roll out to the production cluster in early November with the 1.25wmf6 release branch.

An investigation into the possibility of using a package manage for Javascript libraries in MediaWiki closed with the consensus opinion that we are not ready to chose a package manager at this time. The frontend standards group will revisit this decision in three to six months. It was agreed however that as far as possible javascript libraries should follow the guidelines for library development that are being worked on for PHP code.

Initial work has begun on a Profiler implementation that uses XHProf to collect information about the runtime costs of MediaWiki code. This approach to profiling will enable collection of information on code running on Wikimedia servers without relying on explicit wfProfileIn and wfProfileOut calls. This in turn will make splitting code out of MediaWiki core easier.
