+ *** POTENTIAL INCOMPATIBILITY *** (tclInt.h and tclCompile.h)
+ Extensions that access internals defined in tclInt.h and/or
+ tclCompile.h may lose both binary and source compatibility. The
+ relevant changes are:
+ 1. 'struct Var' is completely changed, all acceses to its internals
+ (either direct or via the TclSetVar* and TclIsVar* macros) will
+ malfunction. Var flag values and semantics changed too.
+ 2. 'struct Bytecode' has an additional field that has to be
+ initialised to NULL
+ 3. 'struct Namespace' is larger, as the varTable is now one
+ pointer larger than a Tcl_HashTable. Direct access to its fields
+ will malfunction.
+ 4. 'struct CallFrame' grew one more field (the second such growth
+ with respect to Tcl8.4).
+ 5. api change for the functions TclFindCompiledLocal,
+ TclDeleteVars and many internal functions in tclVar.c
+
+ Additionally, direct access to variable hash tables via the
+ standard Tcl_Hash* interface is to be considered as deprecated. It
+ still works in the present version, but will be broken by further
+ specialisation of these hash tables. This concerns especially the
+ table of array elements in an array, as well as the varTable field
+ in the Namespace struct.
