This is a summary of recent technology and site configuration changes that affect the English Wikipedia. Note that some changes described here have not yet gone live as of press time; the English Wikipedia is currently running version 1.44.0-wmf.4 (a8dd895), and changes to the software with a version number higher than that will not yet be active. Configuration changes and changes to interface messages, however, become active immediately.
