Summary of Changes since Tcl/Tk 8.4.3:
--------------------------------------

The following were the main changes in Tcl/Tk 8.4.4.  A complete list
can be found in the changes file at the root of the source tree.  The
more complete ChangeLog is also included with each source release.  This
is a patch release, so it primarily included bug fixes and corrections
to erratic behavior.  Below are only the most notable changes.

 * Reverted cmdName Tcl_ObjType change to allow extensions that poke
   into Tcl_Obj ptr internals to function again (TclBlend, e4graph, ...)

 * Stop eval of bytecode in a deleted interp

 * Mac OS X build system rewrite

 * Numerous doc improvements

 * Corrected segfault in invalid 'if' statement parsing

 * Enable -DTCL_UTF_MAX=6 during build to indicate UCS-4 mode.
   This is not the recommended build mode (UCS-2 remains the default).

 * 64-bit corrections in thread notifier

 * Safe base tests normalized paths

 * Improved cygwin path support (when building with cygwin libraries)

 * Improved MT-safety of VFS filesystem records

 * Recognize user:password in URL for http::geturl

   adjacent panedwindows
