It also includes several other new features such as -namespaces and binary I/O, plus many bug fixes. The compiler introduces -a few incompatibilities that may affect existing Tcl scripts; the -incompatibilities are relatively obscure but may require modifications -to some old scripts before they can run with this version. The compiler -introduces many new C-level APIs, but the old APIs are still supported. -See below for more details. +corresponds to release 8.0.
