+Changes in 1.01 (09 Apr 2000)
+  * win32/pe: fixed an uncompression problem in DLLs with empty
+    fixup sections

+    PE header was set incorrectly
+
+Changes in 1.00 (26 Mar 2000)
+  * documentation updates
+  * watcom/le: do not duplicate the non-resident name table

+    results in program exit (instead of crash ;-)
+  * win32/pe: new option: `--compress-resources=0'
+  * win32/pe: reduced memory requirement during uncompression, some
+    files might even require LESS memory when they're compressed

+  * win32/pe: improved relocation handling, 16-bit relocations should work
+  * win32/pe: new option `--strip-relocs' (only if you know what you are doing)

+  * improved compression ratio
+  * improved compression speed
