++The birthday release includes a new Search capability inside the sort package. +It takes an unusual but very general and easy-to-use approach to searching +arbitrary indexable sorted data. See the documentation for details: + http://golang.org/pkg/sort/#Search + +The ARM port now uses the hardware floating point unit (VFP). It still has a +few bugs, mostly around conversions between unsigned integer and floating-point +values, but it's stabilizing. + +In addition, there have been many smaller fixes and updates: + +* 6l: generate dwarf variable names with disambiguating suffix. +* container/list: make Remove return Value of removed element. + makes it easier to remove first or last item. +* crypto: add cast5 (default PGP cipher), + switch block cipher methods to be destination first. +* crypto/tls: use pool building for certificate checking +* go/ast: change embedded token.Position fields to named fields + (preparation for a different position representation) +* net: provide public access to file descriptors (thanks Keith Rarick) +* os: add Expand function to evaluate environment variables. +* path: add Glob (thanks Benny Siegert) +* runtime: memequal optimization (thanks Graham Miller) + prefix all external symbols with "runtime·" to avoid + conflicts linking with external C libraries. ++
