 ==============  RELEASE 0.4.0.1  ==============
 
+20060626	Continuing on SPARC emulation (beginning on the 'save'
+		instruction, register windows, etc).
+20060629	Planning statistics gathering (new -s command line option),
+		and renaming speed_tricks to allow_instruction_combinations.
+20060630	Some minor manual page updates.
+		Various cleanups.
+		Implementing the -s command line option.
+20060701	FINALLY found the bug which prevented Linux and Ultrix from
+		running without the ugly hack in the R2000/R3000 cache isol
+		code; it was the phystranslation hint array which was buggy.
+		Removing the phystranslation hint code completely, for now.
+20060702	Minor dyntrans cleanups; invalidation of physpages now only
+		invalidate those parts of a page that have actually been
+		translated. (32 parts per page.)
+		Some MIPS non-R3000 speed fixes.
+		Experimenting with MIPS instruction combination for some
+		addiu+bne+sw loops, and sw+sw+sw.
+		Adding support (again) for larger-than-4KB pages in MIPS tlbw*.
+		Continuing on SPARC emulation: adding load/store instructions.
+20060704	Fixing a virtual vs physical page shift bug in the new tlbw*
+		implementation. Problem noticed by Jakub Jermar. (Many thanks.)
+		Moving rfe and eret to cpu_mips_instr.c, since that is the
+		only place that uses them nowadays.
+20060705	Removing the BSD license from the "testmachine" include files,
+		placing them in the public domain instead; this enables the
+		testmachine stuff to be used from projects which are
+		incompatible with the BSD license for some reason.
+20060707	Adding instruction combinations for the R2000/R3000 L1
+		I-cache invalidation code used by NetBSD/pmax 3.0, lui+addiu,
+		various branches followed by addiu or nop, and jr ra followed
+		by addiu. The time it takes to perform a full NetBSD/pmax R3000
+		install on the laptop has dropped from 573 seconds to 539. :-)
+20060708	Adding a framebuffer controller device (dev_fbctrl), which so
+		far can be used to change the fb resolution during runtime, but
+		in the future will also be useful for accelerated block fill/
+		copy, and possibly also simplified character output.
+		Adding an instruction combination for NetBSD/pmax' strlen.
+20060709	Minor fixes: reading raw files in src/file.c wasn't memblock
+		aligned, removing buggy multi_sw MIPS instruction combination,
+		etc.
+20060711	Adding a machine_qemu.c, which contains a "qemu_mips" machine.
+		(It mimics QEMU's MIPS machine mode, so that a test kernel
+		made for QEMU_MIPS also can run in GXemul... at least to some
+		extent.)  Adding a short section about how to run this mode to
+		doc/guestoses.html.
+20060714	Misc. minor code cleanups.
+20060715	Applying a patch which adds getchar() to promemul/yamon.c
+		(from Oleksandr Tymoshenko).
+		Adding yamon.h from NetBSD, and rewriting yamon.c to use it
+		(instead of ugly hardcoded numbers) + some cleanup.
+20060716	Found and fixed the bug which broke single-stepping of 64-bit
+		programs between 0.4.0 and 0.4.0.1 (caused by too quick
+		refactoring and no testing). Hopefully this fix will not
+		break too many other things.
+20060718	Continuing on the 8253 PIT; it now works with Linux/QEMU_MIPS.
+		Re-adding the sw+sw+sw instr comb (the problem was that I had
+		ignored endian issues); however, it doesn't seem to give any
+		big performance gain.
+20060720	Adding a dummy Transputer mode (T414, T800 etc) skeleton (only
+		the 'j' and 'ldc' instructions are implemented so far). :-}
+20060721	Adding gtreg.h from NetBSD, updating dev_gt.c to use it, plus
+		misc. other updates to get Linux 2.6 for evbmips/malta working
+		(thanks to Alec Voropay for the details).
+		FINALLY found and fixed the bug which made tlbw* for non-R3000
+		buggy; it was a reference count problem in the dyntrans core.
+20060722	Testing stuff; things seem stable enough for a new release.
