The October CU for SharePoint 2010 is now available for download. Continuing the theme started by the August CU for 2010, the October CU for SharePoint 2010 also consolidates the update packages depending on what products you have installed, you will only need to install 1 patch. Similar to how things were done with the August updates, here are your patches for SharePoint 2010 and related products:

Microsoft SharePoint Foundation (MSF) October CU Server-Package(Article is not Live yet for the MSF Package):
http://support.microsoft.com/default.aspx?scid=kb;EN-US;2394323

Microsoft SharePoint Server 2010 (MSS) October CU Server-Package:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;2394320

Microsoft SharePoint Server 2010 + Project Server 2010 October CU Server-Package:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;2394322

Though the SharePoint Foundation KB Article is not live yet, the Server-Packages for MSS and MSS + Project include the Foundation Server-Package. Again, similar to the August updates, if you have SharePoint 2010 Server, you only need to install the SharePoint Server 2010 Server-Package as it includes all the Foundation updates as well. The same applies for the MSS + Project Server-Package, it includes all the Project, SharePoint Server and SharePoint Foundation packages. So you should only need to download and install one package.
