Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
tools (common/template): changed blog_date filter to date_days Instead of returning the whole sentence, date_days only return the number of days between now and the given timestamp. This way the template author can choose how to use it, and translation can be done template side.
