ArcGIS 10.0 Service Pack 4 (SP4) for English, is now available to our users for download via the ArcGIS Resource Center. This Service Pack contains performance improvements and maintenance fixes. Here are links to the downloads:
Release Note: ArcGIS 10.0 Service Pack 4 for the other five languages (French, German, Japanese, Simplified Chinese and Spanish) will be released in the next two weeks. A follow up blog entry will be posted to announce the availability once they are ready.

That’s a hefty download; 439 Mb for the ArcGIS Desktop Service Pack. Why doesn’t ESRI provide a checksum/hashcode so that users can verify the integrity of the downloaded Service Pack prior to installation? I know from the past that many people have had problems with installed Service Packs because there was some corruption in the downloaded file.
Thank you. This is a very good idea. We will look into implementing the use of the file checksum for the 10 SP5 release.
I agree with jvondrackek. I submitted this as an “idea” to the ideas.esri.com website.. link: https://c.na1.visual.force.com/apex/ideaView?id=08730000000bvKVAAY if anyone wants to vote it up.
Also in case anyone is interested, the MD5 checksum calculated using the File Checksum Integrity Verifier from MS is:

Thanks for submitting your idea, Chris! Hope it gets lots of votes of support.
When will a list of bug fixes & improvements be available? Perhaps I’m not looking in the right location?
Issues addressed with 10.0 Service Pack 4
We’ve encountered some serious bugs with ArcGIS Service Pack 4 related to spatial joins where records are reverted to null at random in the output. We submitted a bug incident request with ESRI Canada and suggested that staff not install the Service Pack at this time. You might want to check this on one of your machines before rolling out this upgrade to your users as well.
Tested this myself – got the same problem. In fact, most records came out null.
This would be a good thing to contact Esri Technical Support about — here is a link to their site: http://support.esri.com/en
Just an update that Redlands have confirmed that this is a bug introduced with SP4. It has been logged under NIM079126 here: http://support.esri.com/en/bugs/nimbus/TklNMDc5MTI2
Thanks for the update, Ryan!
The notes on NIM079126 seem to indicate that it was “declined”. If you are experiencing this issue, I would suggest that you do contact tech support, reference the bug# , and give them specific details how to reproduce the problem. Otherwise, it may never get fixed.

I’ve posted about this.
I think it’s failing when you have a point outside the join polys

I am having problems with ArcMap 10 SP4. When I drag floating tool bars to pin them to the main tool bar, arcmap hangs and crashes. Also sometimes when I select print, arcmap hangs and crashes. Anyone else having the same problem or know its cause. ArcMap10 was pretty stable until I installed SP4. Thanks!
This is something that you would probably do best to contact Esri Technical Support about — here is a link to their site: http://support.esri.com/en
I am having this same problem too.
This is also a documented bug that has been around for a while (NIM072258). It’s an Internet Explorer 9 compatibility issue in Window 7 (and possibly other operating systems?). The culprit is having the Search Window pinned while trying to move toolbars. Unpin/hide the search window, and your docking/undocking should work fine. Or perhaps you can roll back to IE8.
