Highlights @[...] syntax properly inside quasiquote. + + - The third argument (the default value if a key is not found) can be omitted + when indexing hashes with the [hash key] syntax. It defaults to nil. + + - The dwim operator (and thus [] syntax) is even more Lisp-1 like. It + now has Lisp-1 namespace semantics for evaluating arguments + that are symbols. + + - A new operator called "op" as been added. This allows simple lambda + functions to be written as partial evaluatios of functions, with implicit + arguments as well as numbered/rest arguments appearing in the body. + + + Bugs + + - Fixed missing type check in hash module that allows bad code + to crash interpreter instead of getting an excepion. + + - Fixed regression in TXR 55 which broke computed field widths in output + variables. + + - Fixed incorrect UTF-8 decoding of some code points. + + - Closed several security holes in UTF-8 decoder by recognizing all invalid + UTF-8 sequences, and mapping invalid bytes in such a way that any byte + sequence processed by the decoder into Unicode code points will be + recovered exactly when encoded back into UTF-8. + + + TXR 55 2011-01-26 |
