+The Scanner type in the
+bufio package
+has had a bug fixed that may require changes to custom
+split functions.
+The bug made it impossible to generate an empty token at EOF; the fix
+changes the end conditions seen by the split function.
+Previously, scanning stopped at EOF if there was no more data.
+As of 1.4, the split function will be called once at EOF after input is exhausted,
+so the split function can generate a final empty token
+as the documentation already promised.
-bufio: handling of empty tokens at EOF changed, may require scanner change (CL 145390043) -syscall: now frozen (CL 129820043); go.sys subrepo created: http://golang.org/s/go1.4-syscall -+
+Updating: Custom split functions may need to be modified to +handle empty tokens at EOF as desired. +
+ +
+The syscall package is now frozen except
+for changes needed to maintain the core repository.
+In particular, it will no longer be extended to support new or different system calls
+that are not used by the core.
+The reasons are described at length in a
+separate document.
+
+A new subrepository, go.sys, +has been created to serve as the location for new developments to support system +calls on all kernels. +It has a nicer structure, with three packages that each hold the implementation of +system calls for one of +Unix, +Windows and +Plan 9. +These packages will be curated more generously, accepting all reasonable changes +that reflect kernel interfaces in those operating systems. +See the documentation and the article mentioned above for more information. +
+ +
+Updating: Existing programs are not affected as the syscall
+package is largely unchanged from the 1.3 release.
+Future development that requires system calls not in the syscall package
+should build on go.sys instead.

&map[string]int{"one": 1} now prints
&map[one: 1] rather than as a hexadecimal pointer value.
