Newton Internet Enabler: MP130 update 2.0 (526167)

I came across this new system update (526167) while downloading the newest version of the Newton Internet Enabler. I checked my Newton 130 and it is 2.0 (526060). Is this update newer than the one which shipped with the 130 and what is it for?
The newest Newton system update for the MessagePad 130 (version 526167) is used to correct problems with applications that allocate large chunks of store memory, such as the Newton Internet Enabler (NIE).

Developers of products which use the NIE may also be distributing this update. This update will not be part of any official system update offered to MessagePad owners at this time.

This update is designed for the NIE developers and for customers who purchase a product that uses the NIE software. The update can be found on the Apple Developer Services web site.

For developers, questions on NIE v1.0 will be addressed through the usual channel of support.

Any particular NIE connectivity issues must be addressed with your Internet Service Provider.
