Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Servlet version 1.18b1 - new transfer mode "rawfile" with mime-type application/octet-stream - finally proper logging with Log4J! - therefore a lot of debugging-prints changed - the Util class is now useless - ServletOps and FileOps are now purely static
