 * Version
 
+###:
+    Abstracted powf() to an osdepend wrapper. (Needed for Windows.)
+    Fixed a @ceil bug, for some C math libraries.
+
+0.4.6:
+    Added floating-point math feature.
+    Updated winstart.c. (Thanks David Kinder.)
+    Fixed @random even more, on Windows.
+    @verify works right on game files with extended memory.
+    @getiosys works right when the two store operands are different
+    variable types. (E.g., one local and one global.)
+
+0.4.5:
+    VERIFY_MEMORY_ACCESS now detects writes to the ROM section of memory.
+    Fixed off-by-eight bug in @astorebit and @aloadbit with negative bit
+    numbers.
+    Fixed an obscure bug with division and modulo of $80000000. (Thanks 
+    Evin Robertson.)
+    Fixed an extremely obscure problem with changing I/O mode in the middle
+    of printing a number.
+    Glk array/string operations are now checked for memory overflows
+    (though not for ROM writing). This generates a warning at present;
+    in the future, it will be a fatal error.
+    Better fix for the @random bug.
+
 0.4.4:
     Added profiling code, which is turned off by default. To compile it 
     in, define VM_PROFILING in Makefile or in glulxe.h.
