Zope 2.1.6 has been released - you can download it from Zope.org:

http://www.zope.org/Products/Zope/2.1.6/

This release fixes a few issues with Friday's 2.1.5 security update release:

• Some bits from the currently development branch got into the 2.1.x release branch, causing problems for folks using certain database adapters - this has been fixed.

• A fix to Acquisition that happened in 2.1.5 caused a problem with ZClasses, since some of the code in Factory.py previously worked around the problem and now no longer needed to. This has been fixed in 2.1.6.

Users of the SiteAccess product should note that the security changes in 2.1.5 necessarily require a change to the SiteAccess product - as he noted in a previous email to the zope list, Evan will be releasing an updated SiteAccess shortly.

Also, the XMLDocument product has a buglet that was made effective by a fix to a bug in Acquisition. Prior to 2.1.5, there were cases where acquisition-wrapped objects sometimes didn't have their full acquisition context. This was fixed in 2.1.5. Unfortunately, some applications may depend on the old incomplete wrapping. :(

Currently, when you add an XML document, you will get a WrongDocumentException. This can be fixed by changing:

if document and ownerDocument and document != ownerDocument:

to:

if (document and ownerDocument and getattr(document, aq_base, document) is not getattr(ownerDocument, aq_base, ownerDocument) ):

in the appendChild method in class Node in file Node.py. A new rev of XMLDocument containing this fix will be available soon.

Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.1.x site. These updates are available for those currently using the 2.1.x source release or the 2.1.x binary releases for either solaris or linux.

To apply a differential update to your site:

• download the appropriate .tgz file from zope.org
• shutdown your Zope process
• copy the .tgz to your Zope directory and extract it
• run w_pcgi or wo_pcgi if you are not using a binary release
• restart your process
