Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Editor: * The editor will now force filenames to be lowercase, as VFS does not like uppercase path names. * If a map filename does not have a .xml extension on save, it will be automatically added. * Log modules set to "all" by default. Only new users will be affected by this without having to modify or remove their configuration file. * Log level set to LOGLEVEL_WARN
