Karl Wettin updated LUCENE-1142:
--------------------------------

    Attachment: LUCENE-1142.txt

 * Fixed some conflicts against trunk
 * Backwards compatibility messages

This is what I did with README:
{noformat}
+IMPORTANT NOTICE ON BACKWARDS COMPATIBILITY!
+
+An index created using the Snowball module in Lucene 2.3.2 and below
+might not be compatible with the Snowball module in Lucene 2.4 or greater.
+
+For more information about this issue see:
+https://issues.apache.org/jira/browse/LUCENE-1142
{noformat}

I also added this text the the package javadocs.

About LUCENE-740, all changes in the patches of that issue originates from the Snowball repository and is thus also available in this patch.

Should I go ahead and commit this for 2.4?
