Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Convert internal error/warning handling framework to a new unified system Replace the ad hoc error and warning handling with a new system that codifies the errors with specific codes. This makes it possible in the future for error numbers to be used for testing and other purposes. It also makes sure the error strings themselves are consistent. Thanks to Erik G <erik@6809.org> for the patch.
