Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add new motd_sequential module. This module lets you define numbered messages shown to each user in order, but only once per user, and persistent across server restarts. Useful for notifying users of added features and changes in an incremental fashion.
