Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
- Added Identity and NotIdentity tokens. - Added constructor to Parser. Added error method and parseCondExpression(). - Added parseAssignExpression() method. - Moved arguments() function from error() method of Lexer to module Information. - Added members and constructor to BinaryExpression. - Added XYZAssignExpression classes. - Added calls to super() to classes that inherit from BinaryExpression.
