To use Go on these systems you must +[[http://golang.org/doc/install/source][install from source]]. + +Changes to the runtime have improved the +[[http://golang.org/doc/go1.3#performance][performance]] of Go binaries, +with an improved garbage collector, a new +[[http://golang.org/s/contigstacks]["contiguous" goroutine stack management strategy]], +a faster race detector, and improvements to the regular expression engine. + +As part of the general [[http://golang.org/s/go13linker][overhaul]] of the Go +linker, the compilers and linkers have been refactored. The instruction +selection phase that was part of the linker has been moved to the compiler. +This can speed up incremental builds for large projects. + +The [[http://golang.org/doc/go1.3#garbage_collector][garbage collector]] is now +precise when examining stacks (collection of the heap has been precise since Go +1.1), meaning that a non-pointer value such as an integer will never be +mistaken for a pointer and prevent unused memory from being reclaimed. This +change affects code that uses package unsafe; if you have unsafe code you +should read the [[http://golang.org/doc/go1.3#garbage_collector][release notes]] +carefully to see if your code needs updating. + +We would like to thank the many people who contributed to this release; +it would not have been possible without your help. + +So, what are you waiting for? +Head on over to the [[http://golang.org/dl/][downloads page]] and start hacking. -- cgit v1.2.3
