The replication admin page on slaves used to have an auto-reload set to reload every few seconds. In the official 1.4 release this doesn't seem to be working, but it does in a nightly build from early June. Was this changed on purpose or is this a bug? I looked through CHANGES.txt to see if anything was mentioned related to this but didn't see anything. If it's a bug I'll open an issue in JIRA>
