Steve, This is pretty longwinded and maybe just the first sentence will suffice 
with "see the wiki for more information."  All of this is documented there, 
more or less.  None of this will affect very many people.

----------
The DataImportHandler contrib module has some minor backwards-compatibility 
breaks in this release.

1. Both NumberFormatTransformer & DateFormatTransformer default to the "root" 
locale if none is specified.  Prior versions used the JVM default locale.  It 
is strongly advised that users always specify the locale when using this 
transformer. See https://issues.apache.org/jira/browse/SOLR-4095

2. Both FileDataSoruce and FieldReaderDataSource default to UTF-8 encoding if 
none is specified.  Prior versions used the JVM default.  See 
https://issues.apache.org/jira/browse/SOLR-4096 .  Also, the behavior of 
DataSource and encoding may change again in a subsequent release.  See 
https://issues.apache.org/jira/browse/SOLR-2347 .

3. The "formatDate" evaluator now defaults to using the "root" locale.  Prior 
versions used the JVM default.  Both the locale & timezone now can be specified 
using new optional parameters.  See 
https://issues.apache.org/jira/browse/SOLR-4086 & 
https://issues.apache.org/jira/browse/SOLR-2201 .

4. The "dataimport.properties" file, which holds the last indexed timestamp for 
use with delta imports, is now by default using the "root" locale.  This 
default can be overridden using the new <propertyWriter /> tag in 
data-config.xml.  Prior versions used the default JVM locale.  This is only of 
concern if your default locale uses different DataFormatSymbols than the "root" 
locale and if your installation depends on these alternate symbols (for 
instance if your RDMBS takes dates using your locale-specific date symbols). 
See https://issues.apache.org/jira/browse/SOLR-4051

5. The experimental DIHProperties interface has changed, and is now an abstract 
class.  This will require code changes for anyone who has a custom 
DIHProperties.  Also note that future API changes with this class are possible 
in subsequent releases.  See https://issues.apache.org/jira/browse/SOLR-4051

6. The Evaluator framework has received extensive refactoring.  Some custom 
evaluators may require code changes.  Specifically, public or protected methods 
from the EvaluatorBag class have been moved to the Evaluator abstract class 
that all Evalutators must extend.  See 
https://issues.apache.org/jira/browse/SOLR-4086

Subject: 4.1 release notes: please review

I took a crack at the Solr release note.

I added CommonTermsQuery to the Lucene release note that Robert has been 
maintaining - looks good to me otherwise.

Please help me whip these into shape.

Thanks,
