Tcl Source Code

2012-04-11  Jan Nijtmans  <[email protected]>

	* win/tclWinInit.c:     [Bug 3448512]: clock scan "1958-01-01" fails only
	* win/tcl.m4:           in debug compilation.
	* win/configure:
	* unix/tcl.m4:          Use NDEBUG consistantly meaning: no debugging.
	* unix/configure:
	* generic/tclBasic.c:
	* library/dde/pkgIndex.tcl   Use [::tcl::pkgconfig get debug] in stead
	* library/reg/pkgIndex.tcl   of [info exists ::tcl_platform(debug)]

	***POTENTIAL INCOMPATIBILITY***
	The variables $tcl_platform(debug) and $tcl_platform(threaded) no longer
	exist. They don't belong in the tcl_platform array, were never documented,
	disturbed the platform-1.1 test, $tcl_platform(debug) was only available
	on Windows anyway, and TIP #59 provides a much better alternative.

2012-04-10  Donal K. Fellows  <[email protected]>

	* generic/tcl.h (TCL_DEPRECATED_API): [Bug 2458976]: Added macro that
	can be used to mark parts of Tcl's API as deprecated. Currently only
	used for fields of Tcl_Interp, which TIPs 330 and 336 have deprecated
	with a migration strategy; we want to encourage people to move away
	from those fields.
