There are some interesting and important bug fixes included. Here are some highlights:

Issues fixed in ESXi 5.1 Build 1157734

• When connecting a client device CD-ROM to a VM using the vSphere Client the VM would freeze if the network connection to the client broke.
• The new vmx parameter ethernetx.checkMACAddress (when set to false) allows VMs to be powered on even if their manually defined MAC address is not in the allowed range
• Random disconnects of ESXi 5.1 hosts from vCenter due to problems with the heartbeat thread
• CIM sfcbd going out of service when the HP SMX CIM provider is installed
• VMware Tools fix for compiling the vmci driver on Linux kernel 3.8
• Driver updates: net-e1000 and scsi-hpsa
• A security fix that resolves a stability issue (uh?)

I have updated my ESXi Patch Matrix to include the new build.
