@@ -23,6 +23,18 @@ Extension Modules Library ------- +- A new pickle protocol (protocol 3) is added with explicit support + for bytes. This is the default protocol. It intentionally cannot + be unpickled by Python 2.x. + +- When a pickle written by Python 2.x contains an (8-bit) str + instance, this is now decoded to a (Unicode) str instance. The + encoding used to do this defaults to ASCII, but can be overridden + via two new keyword arguments to the Unpickler class. Previously + this would create bytes instances, which is usually wrong: str + instances are often used to pickle attribute names etc., and text is + more common than binary data anyway. + - Default to ASCII as the locale.getpreferredencoding, if the POSIX system doesn't support CODESET and LANG isn't set or doesn't allow deduction of an encoding. |
