Expiration of Service Pack Blocker Tool for Windows Vista & Windows XP

Brandon LeBlanc — Thu, 29 Jan 2009 18:44:15 GMT

I have some important information for those of you who have installed the Service Pack Blocker Tool for Windows XP or Windows Vista. The Service Pack Blocker Tool temporarily prevents the installation of a service pack through Windows Update, typically for one year after general availability of the service pack. We are announcing the upcoming expiration dates for the Service Pack Blocker Tool for Windows Vista SP1 and Windows XP SP3:

Windows Vista SP1: April 28, 2009
Windows XP SP3: May 19, 2009

After April 28th, Windows Vista SP1 will be delivered via Windows Update. And after May 19th, Windows XP SP3 will also be delivered via Windows Update.

For more information on the Service Pack Blocker Tool, please see this Q&A.

Windows Vista Service Pack 2 Beta

Mike Nash — Sat, 25 Oct 2008 04:13:00 GMT

Hi there, Mike Nash here.

As you know we are getting ready to talk about Windows 7 at the PDC next week. Before we do that, I thought I would give you an update on our latest work for Windows Vista.

We are committed to continually improving Windows, and we've been getting some questions about the timing of the next service pack for Windows Vista. Following the success of Windows Vista Service Pack 1 last spring, we have been working hard on Windows Vista Service Pack 2. As a part of the development and testing process, we're going to start by providing a small group of Technology Adoption Program customers with Windows Vista SP2 Beta for evaluation next Wednesday, October 29. The final release date for Windows Vista SP2 will be based on quality. So we'll track customer and partner feedback from the beta program before setting a final date for the release.

Windows Vista SP2 Beta contains previously released fixes focused on addressing specific reliability, performance, and compatibility issues. We expect Windows Vista SP2 will retain compatibility with applications that run on Windows Vista and Windows Vista SP1 and are written using public APIs.

Because we've adopted a single serviceability model, these improvements are integrated into a single service pack covering both Windows Vista (client) and Windows Server 2008 (server) versions. This should also minimize deployment and testing complexity for our customers.

In addition to previously released updates since the launch of Windows Vista SP1, Windows Vista SP2 contains changes focused on supporting new types of hardware and adding support for several emerging standards:

Windows Vista SP2 adds Windows Search 4.0 for faster and improved relevancy in searches.
Windows Vista SP2 contains the Bluetooth 2.1 Feature Pack supporting the most recent specification for Bluetooth Technology.
Ability to record data on to Blu-Ray media natively in Windows Vista.
Adds Windows Connect Now (WCN) to simplify Wi-Fi Configuration.
Windows Vista SP2 enables the exFAT file system to support UTC timestamps, which allows correct file synchronization across time zones.

One question I know that you will ask is "should I wait for SP2?" The reality is that Windows Vista SP1 is a great platform that is both available on new Windows PCs and available as a free download for systems that are running the "gold" release of Windows Vista. While we will recommend SP2 when it ships, your best bet today is Windows Vista SP1.

I look forward to sharing more about Windows Vista SP2 in the future - stay tuned!

Mojave: The Experiment Continues…

Chris Flores — Wed, 27 Aug 2008 02:08:00 GMT

I'm posting this on behalf of my colleague David Webster:

I'm David Webster --the guy "deep in the ranks" who dreamed up the Mojave Experiment. Today we updated the website with a few new videos, including sharing with you the fiercely debated demos that the participants were shown. We encourage everyone to take a look at the videos, ask questions or air concerns (or even compliments). First I wanted to provide some context and clarify a few things.

It's been a couple weeks since we launched the Mojave Experiment, and the reaction in the blogosphere has been fascinating to watch. You should see my inbox - some of you really liked how the experiment helped you say "I told you so" to haters who'd just jumped on the bandwagon without trying for themselves. Others thought it was interesting but were skeptical about the validity of the project's methodology, and others still questioned our sanity (not the first time) for doing the experiment in the first place. There were lots of questions - some wondered if we rigged the results, cherry picked videos or even brought in actors to pose as consumers. Fair enough. You should be skeptical. After all, the basic message of the Mojave Experiment is decide for yourself. In that spirit, don't take my word for it either. Go ahead and check out the new site for answers to the most frequent questions we got over the last few weeks.

We've also heard from supporters loud and clear that we needed to do more marketing around Windows Vista to regular users, and that is exactly what we are doing with the Mojave Experiment. As we have discussed, we're working to get the Mojave message out to consumers through website updates, retail activities and ads on cable stations. However, I do want to stress that while the Mojave Experiment is part of Microsoft's broader effort to talk about the value of Windows Vista, it is separate from the Crispin, Porter & Bogusky campaign you may have heard about in recent weeks. Stay tuned for more details on that one...for now I'm just here to discuss Mojave.

Well, here's why we went ahead with Mojave in the first place.

It should surprise no one that we believe Windows Vista today is a great product; it may surprise some that most current Windows Vista customers agree. In fact, we researched satisfaction levels among existing Windows Vista customers - the survey found that nearly 9 of 10 (i.e. 89%) of customers are either satisfied or very satisfied with their Windows Vista experience. And, satisfaction is increasing over time - customer sat level is 92% satisfied/very satisfied among those who bought Windows Vista during the last 6 months. More than 180 million Windows Vista licenses have been sold (as of June 30, 2008), and, as analysts have reported, corporate adoption rates are consistent with Windows XP rates in similar timeframes. So looking strictly at customer satisfaction and sales data, things are going very well for Windows Vista.

At the same time, we recognize that noise in the market created by a vocal minority can discourage regular people from trying the product for themselves. We're confident these people would find a lot to like about Windows Vista if they spent even 5-10 minutes taking a closer look. We wanted to confirm that hypothesis and see what happens when people get a second chance to make a first impression.

This led to the idea that led to the test that turned into the Mojave Experiment. And the hypothesis was confirmed when across the board, participants concluded that they needed to take another look before simply accepting what they'd heard. In fact, we had plans for a fun section of the site that highlighted any test subjects who didn't change their minds about Windows Vista. But we didn't get any.

The Windows Vista operating system delivered big changes in security, performance and graphics capabilities. These were long-term changes designed to bring customers forward and they are paying off, but it's true they also created near-term pain for customers immediately following launch - notably, some applications and devices didn't work (or work well) on Windows Vista. The product has come a long way since then. We and our partners have worked extremely hard to fix incompatibilities and optimize drivers for increased performance and stability. We shipped SP1 and countless other Windows Updates that have significantly improved Windows Vista over the last 18 months.

Again, we know from lots of user and non-user data that the closer they look the more they will like it. We just needed to give them a reason to take another look.

Essential Tool for the Job - Microsoft Assessment and Planning Toolkit 3.1 for Windows Vista (RTM Announcement)

Baldwin Ng — Mon, 30 Jun 2008 14:53:00 GMT

RTM Announcement - Microsoft Assessment and Planning Toolkit 3.1

Hello,

It's been a few months since I last blogged about the Microsoft Assessment and Planning Toolkit 3.1 - formerly known as WVHA or Windows Vista Hardware Assessment. Today, I'd like to announce the RTM release of this tool with new capabilities including desktop security assessment, Hyper-V virtualization assessment, and more.

As you know, many of the IT pros out there like you are now spending a lot of time planning for Windows Vista deployments. But many question and challenges remain:

Are my existing PCs compatible to Windows Vista when it comes to Hardware and Device Compatibility?
Will my PCs have BIOS issues after the upgrade to Windows Vista?
Which of my PCs are ripe for an upgrade to Windows Vista? (e.g. CPU too old so it's time to replace them; or just add 512MB system memory and the PCs would be Windows Vista capable!)
What kind of software has been installed?
Are all of my PCs secure? Is Windows Security Center installed? Do they have Anti-Virus or Anti-Malware software installed? How about Windows Firewall settings?
What about application virtualization readiness?

The MAP Toolkit 3.1 is designed to address all of these desktop-side issues from a single tool! The MAP Toolkit is a platform of tools that combines the strength of agentless discovery and report generation capabilities from the previous generation (Windows Vista Hardware Assessment). The pie-chart below is part of an auto-generated readiness report from the MAP Toolkit and it illustrates the level of hardware readiness for Windows Vista upgrades across the desktop infrastructure.

As a matter of fact, if you view the latest MAP Team RTM blog post from yesterday, you will find that the MAP Toolkit 3.1 also havs many server-side and virtualization features including a Hyper-V virtualization candidates assessment and SQL Server discovery!!

Download Microsoft Assessment and Planning Toolkit 3.1 RTM Version
Read documentation about MAP operations on TechNet
Learn tips and see video demos on MAP Team Blog
Join MAP Fan Clubs on TechNet Forum or Facebook
Very importantly, download other Windows Vista Solution Accelerators like the MDT Toolkit, Windows Vista Security Guide and more as well!

Cheers!

Communicating Windows 7

Chris Flores — Tue, 27 May 2008 12:09:00 GMT

Typically when Microsoft ships a new OS (like Windows Vista), we immediately start talking about the next version-which begs two questions: 1) is Microsoft working on a new version of Windows, and if so, 2) why aren't you talking about it?

I thought I would spend a minute giving you an update on where we are. First, yes, we are working on a new version of Windows. As you likely know, it's called Windows 7.We are always looking for new ways to deliver great experiences for our customers. This is especially true of Windows - where we're constantly examining trends in hardware, software and services to ensure that we continue to drive the innovation that has both made Windows the world's most popular operating system and has provided a foundation on which our partners built great products and businesses. When we shipped Windows 2000, we were already working on Windows XP and we started working on Windows Vista even before we released Windows XP. So naturally, we've been thinking about the investments we made in Windows Vista and how we can build on these for the next version of Windows.

What is a little different today is when and how we are talking about the next version of Windows. So, why the change in approach? We know that when we talk about our plans for the next release of Windows, people take action. As a result, we can significantly impact our partners and our customers if we broadly share information that later changes. With Windows 7, we're trying to more carefully plan how we share information with our customers and partners. This means sharing the right level of information at the right time depending on the needs of the audience. For instance, several months ago we began privately sharing our preliminary plans for Windows 7 with software and hardware partners who build on the Windows platform. This gave them an opportunity to give us feedback and gave us the opportunity to incorporate their input into our plans. As the product becomes more complete, we will have the opportunity to share our plans more broadly. Steven Sinofsky, Windows and Windows Live Engineering SVP, talks more about this in his interview with CNET's Ina Fried, published today: http://news.cnet.com/8301-13860_3-9951638-56.html.

We know that this is a change in our approach, but we are confident that it will help us not only to build even better products, but also to be more predictable in the delivery of our products. We also know that this change has led to some confusion, so we would like to share information today that will hopefully clear up some of this.

Before we talk about what's ahead, we should take a look at where we are today with Windows Vista. From a quality perspective, both Windows Vista SP1 and the ecosystem have delivered measurable progress in the six dimensions of quality we track -- device compatibility, application compatibility, reliability, performance, battery life and security. The business results speak for themselves. As of March 31, we had sold more than 140 million Windows Vista licenses, and analyst firm forecasts indicate that Windows Vista adoption among businesses is on a similar pace as Windows XP in similar timeframes. Millions of enterprise users are already running Windows Vista, and we invite you to read their stories published in more than 100 case studies. The benefits they are experiencing range from energy conservation, lower TCO for mobile users, and greater security. Our job is not done, but we've worked hard with our ecosystem to improve the quality of Windows Vista and we're pleased with the customer response.

Another question we often get asked is whether Windows 7 is a major release. The answer is "yes" -- it's hard to describe any product that is used by millions of people and worked on by thousands of engineers as anything else. That said, the long-term architectural investments we introduced in Windows Vista and then refined for Windows Vista SP1 and Windows Server 2008 will carry forward in Windows 7. Windows Vista established a very solid foundation, particularly on subsystems such as graphics, audio, and storage. Windows Server 2008 was built on that foundation and Windows 7 will be as well. Contrary to some speculation, Microsoft is not creating a new kernel for Windows 7. Rather, we are refining the kernel architecture and componentization model introduced in Windows Vista. While these changes will increase our engineering agility, they will not impact the user experience or reduce application or hardware compatibility. In fact, one of our design goals for Windows 7 is that it will run on the recommended hardware we specified for Windows Vista and that the applications and devices that work with Windows Vista will be compatible with Windows 7.

We are well into the development process of Windows 7, and we're happy to report that we're still on track to ship approximately three years after the general availability of Windows Vista. As always, we will be releasing early builds of Windows 7 prior to its general availability as a means to gain feedback, but we're not yet ready to discuss timing and specific plans for any Beta releases. In the meantime, customers can confidently continue with their Windows Vista deployment plans.

Automatic distribution of Windows Vista SP1 begins today

Chris Flores — Wed, 23 Apr 2008 19:55:00 GMT

We're excited about the progress we've made with Windows Vista Service Pack 1. On March 18th, Windows Vista SP1 was made available for customers who chose to manually download and install it from the Microsoft Download Center or Windows Update in English, French, German, Spanish, and Japanese. Last week, we made the remaining languages available - giving WU users the ability to download and install Windows Vista Service Pack in any of 36 supported languages. Today, we're happy to announce that we are beginning automatic distribution of SP1 in English, French, German, Spanish, and Japanese.

So what does this mean? Over the next few months Microsoft will automatically distribute Windows Vista SP1 to PCs that have automatic updates turned on (Learn how to turn on automatic updating) and running English, French, German, Spanish, or Japanese via Windows Update. Automatic distribution will only occur, according to user settings, on PCs ready for SP1. After Windows Vista SP1 downloads, WU will let you know that "new updates are available." You'll then be asked to make a few clicks before the installation of SP1 will begin.

While we're beginning automatic distribution today, you might not see it right away since the distribution process is very gradual. As I called out on April 7th, we'll be distributing the service pack slowly so that we can help Windows users have a good experience.

As I posted above, we made the remaining languages of SP1 available for manual install on the Microsoft Download Center and Windows Update last week. We'd like to let those of you running one of those languages that we'll plan to start automatic distribution of those languages sometime in mid-May.

We hope you enjoy the many improvements that have been made in Windows Vista Service Pack 1 and are excited to start automatic distribution so more of you can begin experiencing the benefits.

Releasing Windows Vista SP1 for more languages

Chris Flores — Tue, 15 Apr 2008 19:00:00 GMT

It has been almost a month since we released Windows Vista SP1 to Windows Update in 5 languages. To date: millions of people have successfully installed Windows Vista SP1 on their PCs. So we're happy to announce the next step for Windows Vista SP1 availability.

We are excited to report that today we are making Windows Vista SP1 available to folks running Windows Vista in any of the supported languages. Starting today, users will be able to choose to manually install Windows Vista SP1 via Windows Update or download the standalone installer from the Microsoft Download Center (x86 and x64) for any of the 36 supported languages, not just English, Spanish, German, French, and Japanese. For now, it is available for users who visit Windows Update or the Microsoft Download Center. We encourage most users to get Windows Vista SP1 via Windows Update-which will provide the best update experience.

Now, Windows Vista PCs of any supported language can update to SP1. You may be aware we also make DVD images of Windows Vista with SP1 available to certain groups like TechNet Plus subscribers, MSDN subscribers, and Volume License (VL) customers. TechNet Plus and MSDN subscribers can download these DVD images in some languages today. The remaining languages will be made available in 2 additional groups over the next few weeks.

For your questions regarding Windows Vista SP1, Brandon has developed a Windows Vista SP1 FAQ designed to help answer many of these basic questions.

Windows Vista SP1 will bring some great improvements to PCs running Windows Vista especially in the areas of security, reliability, and performance. For more details on notable changes in Windows Vista SP1, click here.

Windows Vista SP1 Update

Chris Flores — Mon, 07 Apr 2008 18:32:00 GMT

I have a quick update for you about Windows Vista SP1. The Microsoft Update Blog contains some important information about updates to the SP1 prerequisite distribution plan. Starting tomorrow, we are resuming the automatic update and installation of the Servicing Stack Update.

In mid-April, we will begin distributing SP1 (in the first 5 languages) using the Automatic Update system. We have a lot of Windows users, so not everyone will get it on the same day. In fact, it will go to a small percentage of Windows Vista users each day. The exact timing of when you will receive it depends on when your PC is ready for Windows Vista SP1.

In addition to starting the automatic delivery of the first 5 languages, I wanted to take this opportunity to tell you that also we're on track for the initial release of SP1 in the remaining languages in mid-April.

Language Packs and Windows Vista SP1

Nick White — Mon, 03 Mar 2008 22:24:00 GMT

[Updated 6 Mar 3:01pm PST] Apparently this post has created some confusion, which was the opposite of my intent. Windows Vista SP1 is not delayed. I repeat, aside from our having accelerated SP1 availability to MSDN/TechNet subscribers and volume licensing customers, there has been no change in the release plan Mike outlined in his post announcing SP1.

For clarity's sake, I'll reiterate our release schedule:

For the initial five first wave languages (English, Spanish, German, French, and Japanese):

We will release SP1 to Windows Update and the download center on microsoft.com in mid-March. Customers running Windows Vista with any of these first languages installed can choose to install SP1 by visiting Windows Update. If your PC has a language installed other than one of the 5 listed above, SP1 will not be offered. Additionally, any system that Windows Update determines has a driver Microsoft knows to not update successfully will not be offered SP1.
In mid-April, we will begin delivering Windows Vista SP1 to Windows Vista customers using Automatic Update. In other words, we will begin automatic downloads of SP1 for customers who have chosen to have updates downloaded automatically. Note that, as Mike stated, Windows Update will *not* automatically download SP1 to any system it determines has a driver known to not update successfully. (As updates for the problematic drivers become available, they will be installed automatically by Windows Update so that the result is that more and more systems will automatically get SP1, but only when we are confident they will have a good experience.)
MSDN/TechNet Plus subscribers and volume licensing customers have already been provided access to SP1 in first wave languages, as Mike stated in his follow-on post.

The remaining languages will be released to manufacturing (RTM) in April and availability to customers will follow.

We have some information we'd like to share in regards to Windows Vista SP1 and folks running Language Packs. Some of you may have noticed that after installing Windows Vista SP1 on Windows Vista Ultimate - the Language Packs fail to appear on Windows Update (KB947875).

We will be releasing Windows Vista SP1 in two "waves". The first wave will only provide Windows Vista SP1 to Windows Vista Ultimate PCs running the following 5 Languages: English, French, German, Japanese and Spanish. The second wave will follow shortly after - supporting all 36 languages.

For Windows Update, PCs running the 5 initial languages from the first wave only will be provided with Windows Vista SP1. PCs running Windows Vista Ultimate with any of the other Language Packs installed will not be offered Windows Vista SP1 through Windows Update until they are released. Once the Language Packs are released, Windows Vista SP1 will then be offered for installation.

When installing Windows Vista SP1 from the standalone installer, the standalone installer will only install on Windows Vista Ultimate running any of the 5 languages from the first wave. When installing Windows Vista SP1 on Windows Vista Ultimate with a Language Pack that is not one of the 5 initial Language Packs supported - you will get the following error (KB947876) when attempting to install Windows Vista with the standalone installer:

Windows Vista Service Pack 1 cannot be installed on your computer because the language of Windows Vista you have installed is not supported or you have installed a language pack that is not supported.

Windows Vista Service pack 1 can only be installed on computers running the English, French, German, Japanese and Spanish versions of Windows Vista or computers running only those language packs.

This means if you are running a Language Pack that is not one of the 5 initial Language Packs you will not be able to install Windows Vista SP1 until the other Language Packs are released.

But not to worry - the Language Packs are on their way. We will have more information on exactly when very shortly so stay tuned!

Principled Technologies Tests Windows Vista SP1

Nick White — Tue, 26 Feb 2008 23:25:00 GMT

When Windows Vista was originally released just over a year ago Microsoft commissioned Principled Technologies to compare the overall responsiveness of Windows Vista to Windows XP SP 2 for some common business and home tasks. With the release of Windows Vista Service Pack 1 (SP1) Principled has updated their results. Principled Technologies concluded the following when comparing business scenarios:

Overall, Windows Vista SP1 and Windows XP performed comparably on most test operations. Performance differences between the two operating systems were typically less than a half second. Significant differences of over a second occurred on only nine of 128 measures; Windows Vista SP1 led on eight of those.
Windows Vista SP1 was noticeably more responsive after rebooting than Windows XP on several common business operations.
Overall, Windows Vista SP1 was more responsive than Windows Vista on most comparisons. Performance differences between the two operating systems were typically less than a quarter second.

Principled Technologies also concluded the following when comparing home scenarios:

Overall, Windows Vista SP1 and Windows XP performed comparably on most test operations. Differences were typically less than a half second.
Windows Vista SP1 was noticeably more responsive after rebooting than Windows XP on several common home operations.
Overall, Windows Vista SP1 and Windows Vista performed comparably on most test operations, with differences typically less than a half second.

Update on Windows Vista SP1 Prerequisite KB937287

Nick White — Wed, 20 Feb 2008 00:41:00 GMT

UPDATE 2/21: When calling 1-866-PC-Safety - be sure to let the support agent know you are calling in reference to a Windows Update issue. Also: Microsoft has released KB949358 containing information regarding the issues related to KB937287.

We've heard a few reports about problems customers may be experiencing as a result of KB937287, the servicing stack update I blogged about last week, and I wanted to provide a quick update for you. Immediately after receiving reports of this error, we made the decision to temporarily suspend automatic distribution of the update to avoid further customer impact while we investigate possible causes.

So far, we've been able to determine that this problem only affects a small number of customers in unique circumstances. We are working to identify possible solutions and will make the update available again shortly after we address the issue.

Customers who may be experiencing this issue can use system restore to correct it or contact 1-866-PC-Safety for help troubleshooting. Additional guidance will be available via Microsoft's free Update Support Center soon.

Announcing Windows Vista SP1 Release Candidate (RC)

Nick White — Wed, 05 Dec 2007 20:06:00 GMT

Today we're making available the release candidate (RC) of Windows Vista SP1 via Microsoft Connect, and tomorrow subscribers to TechNet and MDSN will have access to those RC bits too. In addition, the RC will be available to the public next week via Microsoft's Download Center. The release candidate phase of beta software is typically the final phase before the RTM (release-to-manufacturing) of a product and indicates that the code has attained a significant level of performance and stability.

Let me call out several changes made since the Beta release of Service Pack 1 -- many of which came about as a result of direct feedback from our Beta-testing community (thank you!):

The size of the standalone installers have decreased significantly. For example, the standalone installer packages consisting of all 36 languages (x86 and x64 chip architectures) are smaller by over 50%. The standalone installer packages consisting of just the 5 languages (again, x86 and x64) slated for initial release are more than 30% smaller in size.
The required amount of disc space for SP1 installation has also decreased significantly. Furthermore, with the RC, if more space is required to install SP1, an error message will now display exactly how much space is needed to complete the installation.
Previous SP1 versions left behind a directory of files that wasn't needed after installation and occupied about 1GB of space; the RC includes automatic disk clean-up to remove this directory.
Installation reliability has been improved based on bug reports and error codes reported from Windows Update (thanks, Beta testers!). Testing shows that these improvements have significantly increased the proportion of successful installations of the RC.
We've improved the user experience of installing SP1 via Windows Update. During the Beta release, users installed without much guidance from Windows Update. The RC now contains a series of screens with detailed information on SP1.

We also have information to share with IT professionals and system administrators regarding final plans for SP1: we're on track to complete and release SP1 in the first quarter of 2008. When SP1 is complete and we reach our release to manufacturing (RTM) milestone, then shortly after the standalone installer will be released to the Web in two waves. The first wave will consist of the standalone installer (x86 and x64) for the 5 initial languages -- English, French, Spanish, German and Japanese. These languages will be deployed shortly after the RTM milestone. The second wave will launch 8-12 weeks after the first and will consist of all remaining languages, for both chip architectures (x86 and x64).

For administrators managing Windows Vista PCs configured to use Windows Update but not wishing to deploy SP1 upon its release, we have a "blocker patch" that will prevent installation of SP1. Information on the blocker patch can be found here starting tomorrow: http://technet.microsoft.com/windowsvista/bb927794.

If you're not familiar with SP1, you can find more information in this whitepaper. We built Windows Vista SP1 to address specific reliability and performance issues and also to support new types of hardware and several emerging standards. Further, SP1 is designed to make it easier for IT administrators to deploy and manage Windows Vista. Of course, those of you familiar with SP1 already know that some of SP1's improvements are already available via Windows Update.

A reminder to anyone installing the SP1 RC bits: you will need to uninstall the release candidate of SP1 before you can install a later version.

Also, Windows Server 2008 RC1 was made available today for testing; find the download here: http://www.microsoft.com/ws08eval. And, we announced two updates to the WGA program yesterday: the first addresses two exploits to the activation process while the second adjusts how Windows differentiates between the genuine and non-genuine Windows Vista experience. More information can be found here: http://www.microsoft.com/presspass/features/2007/dec07/12-03wga.mspx.

And last, thanks once more to our Beta testing team for their diligence and devotion, as you've made a big impact on this RC release!
