+ TIP#267 IMPLEMENTATION
+
+ * generic/tclIOCmd.c (Tcl_ExecObjCmd): Added -ignorestderr option,
+ * tests/exec.test, doc/exec.n: loosely from [Patch 1476191]
+
2006-12-04 Don Porter <dgp@users.sourceforge.net>
* generic/tclCompExpr.c: Added implementation for the
CompileExprTree() routine that can produce expression bytecode
- directly from internal structures with no need to pass through
- the Tcl_Token array representation. Still disabled by default.
- #undef USE_EXPR_TOKENS to try it out.

2006-12-03 Don Porter <dgp@users.sourceforge.net>
* generic/tclCompExpr.c: Added expr parsing routines that
produce a different set of internal structures representing the parsed
expression, as well as routines that go on to convert those structures
- into the traditional Tcl_Token array format. Use of these routines
- is currently disabled. #undef PARSE_DIRECT_EXPR_TOKENS to enable
- them. These routines will only become really useful when more
- routines that compile directly from the new internal structures are
- completed.
