As I'm sure most people know by now, we've made an updated build of Windows "Longhorn" (build 4074) available. My colleague Mike Taulty pointed to a webcast from Dave Massy that highlights the progress that's been made since the bits we handed out at the PDC. Of course many people (myself included) hate webcasts: they're just too slow and it's hard to pick out the salient points. So I've taken the liberty of posting the notes I took whilst watching this webcast, to give you the choice between watching or skim-reading...
This week we've released a Longhorn Community Technical Preview - the first update to the Longhorn bits distributed to PDC attendees. The updated bits were distributed to WinHEC attendees and are also available to MSDN subscribers. There are 32-bit and 64-bit (both Itanium and 64-bit extensions) images in both debug and retail versions. The SDK has been updated, and a DDK has also been released.
Longhorn has not yet reached beta; this is an interim release that will demonstrate progress, but also regressions. An updated version of Visual Studio is not included, but MSBuild (the new build tool) is included as part of the operating system. It's also imporant to note that this build is not recommended for use as a primary machine for work, since it's not yet stable and hasn't been through the standard security audit. A progress report on the four major pillars of Longhorn:
FundamentalsBase operating system services. Ongoing work in stability, performance and infrastructure, but no specific feature enhancements to draw attention to in this release.
IndigoProvides developers an integrated communications infrastructure - secure and reliable for inter- or even intra-machine communications. No new bits in this release, but expecting significant changes in a future release.
WinFSNot just a storage engine, but also making it easy to find related data quickly. Improvements in stability and performance; infrastructural work will be made available soon.
AvalonBrand new presentation subsystem. Stability and performance improvements checked in, plus a number of new features checked in that were talked about at the PDC, as well as incremental changes to existing features:
