Today I will once again talk about the updates to SharePoint 2013 and this for two reasons:
First, a new update was released this month and then because the links I gave last time is not working anymore.
Here is the link to the article by Todd Klindt in which he lists all the version numbers and give the links for downloading various cumulative update: http://www.toddklindt.com/blog/Lists/Posts/Post.aspx?ID=346
As a bonus, if you do not pay attention to the whole post, know that it has a link to a very useful script to greatly reduce the installation time of the cumulative update! : http://blogs.msdn.com/b/russmax/archive/2013/04/01/why-sharepoint-2013-cumulative-update-takes-5-hours-to-install.aspx
Thanks Todd for those informations!
