[ZODB-Dev] ZODB 3.8.0b1 is released

[Jim Fulton]

The ZODB 3.8.0b1 release is available at:

   http://www.python.org/pypi/ZODB3/3.8.0b1

The major changes since 3.8.0a1 are in Blobs.  Blobs have been re- 
factored a fair bit.

Some backward incompatible changes include:

- The Blob class is now imported from ZODB.blob.

- The Blob openDetached method has bee replaced by the committed  
method.  It is now possible to get a blob file name that can be  
handed to external programs for reading.

- Text-mode blobs are no-longer supported.  All blobs are implicitly  
in binary mode.  There is no need to specify this in the blob open  
method.  The valid modes, 'r', 'w', 'a', and 'r+' are all implicitly  
binary.

- Calling consumeFile with an open file is no-longer supported.

I've also made a 3.8 release branch.  Any bug fixes should be applied  
to the branch, the trunk and earlier branches as appropriate.  Work  
toward 3.9 can proceed on the trunk.
