Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Re-enable proper caching of rendered segments in server. The server keeps records on files that are processed while the server is running. Disk caching is simply disabled for files that are known to use other pages -- because unlike the baker, there's no cheap way to know which files are up to date or not, and rendering is faster enough anyway.
