ZEO 0.2.1 is available

A new release of Zope Enterprise Objects (ZEO) is available at

ZEO turns the Zope object system into a distributed architecture, allowing multiple processors, machines, and networks to act as one website.

This release fixes two bugs in release 0.2:

  • ZEO clients didn't work properly (effectively at all) on Solaris or Windows NT.
  • An error in the handling of the distributed transaction lock could cause a client to stop writing and eventually hang if two clients tried to commit a transaction at the same time.
  • Extra (harmless) messages were sent from the server when invalidating objects during a commit.
  • New protocols (especially loadSerial), used for looking at DTML historical versions, were not implemented.
