+19 April 2007 - The Zope 3 development team announces the Zope 3.4.0a1 release
+
+This release introduces support for binary large objects in the ZODB, provides
+a new postprocessing hook for publishing results and makes all Zope packages
+available as Python eggs.
+
+Development release and feedback
+--------------------------------
+
+This is a development release with alpha quality. It is intended for developers
+to check their applications for compatibility with the new features.
+
+This release *is not intended to be used in production environments*.
+
+We'd love to hear about any bugs you encounter. Please use our bug tracker, the
+mailing lists, and the IRC channel to contact us in case you encounter any
+problems.
+
+This alpha release will be succeeded by a beta which is expected to be
+available by 3rd May 2007. 
+
+For status updates on our roadmap check: https://launchpad.net/zope3/3.4/+milestones
+
+
+What is Zope 3?
+---------------
+
+Zope 3 is a web application server that continues to build on the heritage of
+Zope.  It was rewritten from scratch based on the latest software design
+patterns and the experiences of Zope 2.
+
+The component architecture is the very core of Zope 3 that allows developers to
+create flexible and powerful web applications.
+
+
+Compatibility with Zope 2
+--------------------------
+
+We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2
+use more and more of the Zope 3 packages. But we're not there yet. **You can't
+run Zope 2 applications in Zope 3.**
+
+
+New features and important changes
+----------------------------------
+
+- Updated the shipped ZODB to version 3.8 and introduced optimized handling for
+  large files in  conjunction with ZODB Blob support. Most Blob operations can
+  be handled with O(1) effort now providing a scalable approach to handling
+  large files.
+
+- Introduced IResult hook for postprocessing of publishing results.  This
+  replaces a similar private IResult hook from previous releases.  It is a hook
+  point into which a variety of interesting policies, including in-Zope
+  pipelining, can be placed.  See zope/publisher/httpresults.txt for more
+  details, which itself points to the full details for IResult and
+  IHTTPResponse.setResult in zope/publisher/interfaces/http.py.
+
+- zope.app.testing.functional.ZCMLLayer supports in-process tearDown.  For
+  backwards compatibility, this feature is disabled by default.  You can enable
+  it by passing ``allow_teardown=True`` to ``ZCMLLayer()`` or to
+  ``defineLayer()``.
+
+- Removed unused and untested SFTP code from zope.app.twisted along with all
+  the SSH keys. Removed all the SSL keys also.
+
+- Added new Decimal field type to zope.schema (and DecimalWidget in
+  zope.app.form) and added security declarations for decimal.Decimal objects
+
+- Added new Time field type to zope.schema
+
+- Change the publication object to abort the current transaction if the
+  transaction was doomed. Related to:
+  http://www.zope.org/Collectors/Zope3-dev/655.
+
+There were many more features, restructurings and bugs fixed. Please consult
+the file `doc/CHANGES.txt` in the release for more information.
+
+
+Downloads

+
+Installation instructions for both Windows and Un*x/Linux are now available in
+the top level README.txt file of the distribution. The binary installer is
+recommended for Windows.
