 ==============  RELEASE 0.4.6  ==============
 
+20070616	Implementing the MIPS32/64 revision 2 "ror" instruction.
+20070617	Adding a struct for each physpage which keeps track of which
+		ranges within that page (base offset, length) that are
+		continuously translatable. When running with native code
+		generation enabled (-b), a range is added after each read-
+		ahead loop.
+		Experimenting with using the physical program counter sample
+		data (implemented 20070608) together with the "translatable
+		range" information, to figure out which physical address ranges
+		would be worth translating to native code (if the number of
+		samples falling within a range is above a certain threshold).
+20070618	Adding automagic building of .index comment files for
+		src/file/, src/promemul/, src src/useremul/ as well.
+		Adding a "has been translated" bit to the ranges, so that only
+		not-yet-translated ranges will be sampled.
+20070619	Moving src/cpu.c and src/memory_rw.c into src/cpus/,
+		src/device.c into src/devices/, and src/machine.c into
+		src/machines/.
+		Creating a skeleton cc/ld native backend module; beginning on
+		the function which will detect cc command line, etc.
+20070620	Continuing on the native code generation infrastructure.
+20070621	Moving src/x11.c and src/console.c into a new src/console/
+		subdir (for everything that is console or framebuffer related).
+		Moving src/symbol*.c into a new src/symbol/, which should
+		contain anything that is symbol handling related.
+20070624	Making the program counter sampling threshold a "settings
+		variable" (sampling_threshold), i.e. it can now be changed
+		during runtime.
+		Switching the RELEASE notes format from plain text to HTML.
+		If the TMPDIR environment variable is set, it is used instead
+		of "/tmp" for temporary files.
+		Continuing on the cc/ld backend: simple .c code is generated,
+		the compiler and linker are called, etc.
+		Adding detection of host architecture to the configure script
+		(again), and adding icache invalidation support (only
+		implemented for Alpha hosts so far).
+20070625	Simplifying the program counter sampling mechanism.
+20070626	Removing the cc/ld native code generation stuff, program
+		counter sampling, etc; it would not have worked well in the
+		general case.
+20070627	Removing everything related to native code generation.
+20070629	Removing the (practically unusable) support for multiple
+		emulations. (The single emulation allowed now still supports
+		multiple simultaneous machines, as before.)
+		Beginning on PCCTWO and M88K interrupts.
+20070723	Adding a dummy skeleton for emulation of M32R processors.
+20070901	Fixing a warning found by "gcc version 4.3.0 20070817
+		(experimental)" on amd64.
+20070905	Removing some more traces of the old "multiple emulations"
+		code.
+		Also looking in /usr/local/include and /usr/local/lib for
+		X11 libs, when running configure.
+20070909	Minor updates to the guest OS install instructions, in
+		preparation for the NetBSD 4.0 release.
+20070918	More testing of NetBSD 4.0 RC1.
