<p>This page summarizes the changes between tagged releases of Go.
For full details, see the <a href="http://code.google.com/p/go/source/list">Mercurial change log</a>.</p>
+<h3 id="2011-02-01">2011-02-01</h3>
+
+<pre>
+This release includes significant changes to channel operations and minor
+changes to the log package. Your code will require modification if it uses
+channels in non-blocking communications or the log package's Exit functions.
+
+Non-blocking channel operations have been removed from the language.
+The equivalent operations have always been possible using a select statement
+with a default clause. If a default clause is present in a select, that clause
+will execute (only) if no other is ready, which allows one to avoid blocking on
+a communication.
+
+For example, the old non-blocking send operation,
+
+ if ch <- v {
+ // sent
+ } else {
+ // not sent
+ }
+
+should be rewritten as,
+
+ select {
+ case ch <- v:
+ // sent
+ default:
+ // not sent
+ }
+
+Similarly, this receive,
+
+ v, ok := <-ch
+ if ok {
+ // received
+ } else {
+ // not received
+ }
+
+should be rewritten as,
+
+ select {
+ case v := <-ch:
+ // received
+ default:
+ // not received
+ }
+
+This change is a prelude to redefining the 'comma-ok' syntax for a receive.
+In a later release, a receive expression will return the received value and an
+optional boolean indicating whether the channel has been closed. These changes
+are being made in two stages to prevent this semantic change from silently
+breaking code that uses 'comma-ok' with receives.
+There are no plans to have a boolean expression form for sends.
+
+Sends to a closed channel will panic immediately. Previously, an unspecified
+number of sends would fail silently before causing a panic.
+
+The log package's Exit, Exitf, and Exitln functions have been renamed Fatal,
+Fatalf, and Fatalln respectively. This brings them in line with the naming of
+the testing package.
+
+The port to the "tiny" operating system has been removed. It is unmaintained
+and untested. It was a toy to show that Go can run on raw hardware and it
+served its purpose. The source code will of course remain in the repository
+history, so it could be brought back if needed later.
+
+This release also changes some of the internal structure of the memory
+allocator in preparation for other garbage collector changes.
+If you run into problems, please let us know.
+There is one known issue that we are aware of but have not debugged yet:
+ http://code.google.com/p/go/issues/detail?id=1464&.

+ * with tiny frames, the stack is allowed to protrude
+ * StackSmall bytes below the stack guard. Functions
+ * with large frames don't bother with the check and
+ * always call morestack. The sequences are

+ *
+ * guard = g->stackguard
+ * frame = function's stack frame size
+ * argsize = size of function arguments (call + return)
+ *

+ * The bottom StackGuard - StackSmall bytes are important:
+ * there has to be enough room to execute functions that
+ * refuse to check for stack overflow, either because they
+ * need to be adjacent to the actual caller's frame (deferproc)
+ * or because they handle the imminent stack overflow (morestack).
+ *
+ * For example, deferproc might call malloc, which does one
+ * of the above checks (without allocating a full frame),
+ * which might trigger a call to morestack. This sequence
+ * needs to fit in the bottom section of the stack. On amd64,
+ * morestack's frame is 40 bytes, and deferproc's frame is 56 bytes.
+ * That fits well within the StackGuard - StackSmall = 128 bytes
+ * at the bottom. There may be other sequences lurking or yet to

-This directory contains a simple example of how one might
-start Go running on bare hardware. There is currently code
-for 386 and arm.
-
-
-386
-
-It is very primitive but can run go/test/sieve.go, the concurrent
-prime sieve, on a uniprocessor.
-
-To run, first build the tools by running all.bash with GOARCH=386
-and GOOS set to your normal GOOS (linux, darwin). Then:
-
- export GOOS=tiny
- cd $GOROOT/src/pkg/runtime
- make clean
- make install
- cd tiny
- 8g $GOROOT/test/sieve.go
- 8l sieve.8
- 8l -a sieve.8 >sieve.asm # can consult sieve.asm for debugging
- dd if=/dev/zero of=disk count=10000
- cat bootblock 8.out | dd of=disk conv=notrunc
-
-Use the built-in print(text string) function to print to the
-console.
-
-
-BOCHS
-
-You may have to tweak the .bochsrc depending on your system,
-and you may need to install the Bochs emulator.
-
- $ cp dot-bochsrc .bochsrc
- $ $EDITOR .bochsrc # tweak it if required
- $ bochs
-
-
-ORACLE xVM VIRTUALBOX
-
-Install VirtualBox. Then:
-
- Build 'disk' (described above under '386').
-
- $ VBoxManage convertfromraw disk go-tiny.vdi
- $ VirtualBox
- create a new VM; as disk use the go-tiny.vdi image.
- start the vm.
-
-
-QEMU / KVM
-
-This should work the same for qemu and kvm (really: qemu-kvm).
-
- Build 'disk' (described above under '386').
-
- $ qemu -hda disk
-
-
-ARM
-
-First build the toolchain using GOARCH=arm and GOOS=linux. When
-you build your embedded code set GOARCH=tiny.
-
- export GOOS=tiny
- cd $GOROOT/src/pkg/runtime
- make clean
- make install
-
-On arm the tiny runtime doesn't define a low level write function. You can either
-define a stub if you don't need debug output, or more usefully, define it to
-print to some debug serial port. Here is a sample function that prints to
-the DBGU on an at91sam7s:
-
-#define DBGU_CSR ((uint32*) 0xFFFFF214) // (DBGU) Channel Status Register
-#define US_TXRDY ((uint32) 0x1 << 1) // (DBGU) TXRDY Interrupt
-#define DBGU_THR ((uint32*) 0xFFFFF21C) // (DBGU) Transmitter Holding Register
-
-int32
-write(int32 fd, void* b, int32 n)
-{
- uint32 i;
- uint8* s = (uint8*)b;
-
- for (i = 0; i < n; i++) {
- while ((*DBGU_CSR & US_TXRDY) == 0) {
- }
- *DBGU_THR = *s;
- s++;
- }
- return n;
