<div>packages. Please visit</div><div><br></div><div> <a href="http://pkgs.racket-lang.org/">http://pkgs.racket-lang.org/</a></div><div><br></div><div>for an overview.</div><div><br></div><div>Recent releases included the "beta" versions of the package system.</div>
<div>Racket version 6.0 incorporates many improvements suggested by these</div><div>preliminary experiences:</div><div><br></div><div> * A package is treated as a single collection by default, so it is even</div><div> easier to use a Github repository as a package. Get started quickly:</div>
<div> <a href="http://docs.racket-lang.org/pkg/getting-started.html">http://docs.racket-lang.org/pkg/getting-started.html</a></div><div><br></div><div> * DrRacket includes a new package manager GUI, which is also available</div>
<div> as a stand-alone program via the "gui-pkg-manager" package.</div><div><br></div><div> * The main Racket distribution has been broken into about 200 packages. An</div><div> installation starts with Minimal Racket and then adds these bundled packages.</div>
<div><br></div><div> Alternatively, you may now install a Minimal Racket distribution ---</div><div> which is about 1/10 the size of the main distribution --- and add only</div><div> those packages that you need.</div>
<div><br></div><div> * Package installation supports pre-built packages that include</div><div> compiled byte code and rendered documentation, meaning packages can be</div><div> installed quickly when built versions are a available. All packages in</div>
<div> the main distribution are available in pre-built form.</div><div><br></div><div>Further improvements are in the works, including package documentation on</div><div>the package-catalog web site.</div><div><br></div>
<div>COMPATIBILITY NOTE: PLaneT will remain in place for the foreseeable future,</div><div>but we expect all package work to shift to the new system.</div><div><br></div><div>Beyond the package system, this release brings a number of other changes:</div>
<div><br></div><div> * Racket's HTML documentation has a new and improved look, thanks to</div><div> Matthew Butterick.</div><div><br></div><div> * Racket's JIT compiler supports the ARM architecture.</div><div>
<br></div><div> * Racket supports the Mac's Retina display mode.</div><div><br></div><div> * The profiler provides a new mode that uses the errortrace library to</div><div> produce fine-grained profiles.</div><div><br>
</div><div> * A new contract profiler reports how much time programs spend checking</div><div> contracts, and which contracts are most expensive.</div><div><br></div><div> * The math/flonum library exports fast 105-bit precision operations.</div>
<div><br></div><div> * Check Syntax handles generated identifiers, especially those</div><div> introduced by struct (e.g. field selectors) and Redex (e.g., e_1, e_2)</div><div><br></div><div> * 2htdp/batch-io includes functions for dealing with html/xml in files and</div>
<div> web sites as X-expressions plus conveniences for web-based graph traversals.</div></div><div><br></div></div>
