+KNOWN BUGS IN RELEASE 0.4.0
+---------------------------
 
-If you experience a CRASH, then please run gdb on the core dump, do a back
-trace, and send it to me.
+Because the MIPS emulation mode has been completely rewritten, and I
+haven't had much time to debug it, there are some known (serious) bugs:
 
-Some of the known bugs are:
+	o)  Performance for non-R3000 MIPS emulation is very poor.
 
-  x)  Floating point coprocessor stuff is buggy. Writing a new (portable)
-      framework for fp emulation is in the TODO.
-
-  x)  Linux/DECstation (Debian) oopses extremely often unless -U is used at
-      run-time. I'm not sure yet why it bugs out. With -U, the risk is lower,
-      but not completely gone. _Maybe_ this is a bug in Linux. Why? Because the
-      oops message contains things like ANSI escape codes and characters in
-      registers (including the pc and return address register); this looks like
-      a buffer overflow in the serial driver. (Another thing that gives weight
-      to this theory is that the serial driver in Linux is still being
-      developed.)  But this is just a guess.
-
-  x)  Binary-translated 64-bit stuff checks to see if the top 32 bits are
-      all zeroes or all ones, and then uses 32-bit tables and such. This
-      is a bug. It should check the top 33 bits, not 32. (Alpha only, already
-      fixed for i386?)
-
-  x)  NetBSD/arc 2.0 uses the ASC controller in a way which GXemul cannot yet
-      handle. (NetBSD 1.6.2 works ok.) (Possibly a problem in NetBSD itself,
-      http://mail-index.netbsd.org/source-changes/2005/11/06/0024.html suggests
-      that.)
+	o)  Although the new MIPS emulation system is stable enough to
+	    let many guest operating systems install, it is not stable
+	    enough to let the emulator be compiled inside itself (in a
+	    guest OS) after an install, in all emulation modes.
+
+	o)  Ultrix 4.5 on R3000 in the emulator has problems with keyboard
+	    interrupts; Ultrix 4.2 works fine, though, and Ultrix 4.5 when
+	    run with -C R4400.
+
+These problems will hopefully be corrected in future releases.
