VTP Version 2: If you use VTP in your network, you must decide whether
to use version 1 or version 2. By default, VTP operates in version 1.
VTP version 2 supports these features not supported in version 1:
*Token Ring support-VTP version 2 supports Token Ring Bridge Relay
Function (TrBRF) and Token Ring Concentrator Relay Function (TrCRF)
VLANs. For more information about Token Ring VLANs, see the "Configuring
Normal-Range VLANs" section on page 11-4.
*Unrecognized Type-Length-Value (TLV) support-A VTP server or client
propagates configuration changes to its other trunks, even for TLVs it
is not able to parse. The unrecognized TLV is saved in NVRAM when the
switch is operating in VTP server mode.
*Version-Dependent Transparent Mode-In VTP version 1, a VTP transparent
switch inspects VTP messages for the domain name and version and
forwards a message only if the version and domain name match. Because
VTP version 2 supports only one domain, it forwards VTP messages in
transparent mode without inspecting the version and domain name.
*Consistency Checks-In VTP version 2, VLAN consistency checks (such as
VLAN names and values) are performed only when you enter new information
through the CLI, the Cluster Management Software (CMS), or SNMP.
Consistency checks are not performed when new information is obtained
from a VTP message or when information is read from NVRAM. If the MD5
digest on a received VTP message is correct, its information is
accepted.

Does anyone know of any enhancements in VTP version 2 (other than
token
ring support)?
I believe this is the only enhancement from VTP version 1.
