Our next cumulative update packages are available. The general information you can find in the Office 2010 cumulative update for April 2014. For SharePoint we are still suggesting to install a Full-Server package and that looks as follows.

MSF2010:
2878270 The full server package for Microsoft SharePoint Foundation 2010

Download link: http://support.microsoft.com/hotfix/KBHotfix.aspx?kbnum=2878270&kbln=en-us

SPS2010:
2878250 The full server package for SharePoint Server 2010 and contains also the MSF2010 fixes so you need only this one package.
http://support.microsoft.com/default.aspx?scid=kb;EN-US;2878250  not yet (09/Apr/2014) available

Important for all Server Applications listed above:
After applying the preceding updates, run the SharePoint Products and Technologies Configuration Wizard or “psconfig –cmd upgrade –inplace b2b -wait” in command line. This needs to be done on all servers in the farm with SharePoint installed. You can run psconfig in parallel on all SharePoint machines.
