Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
iOS: Add file browser support for selecting folders/directories. Switch to using UTType on iOS 14 and above. Still getting deprecation warnings on code in the iOS 13 section.... I thought @available(iOS 14, *) would silence those warnings?
