Cassandra Targett commented on SOLR-5036:
-----------------------------------------
The section Upgrading from Solr 4.3.0
----------------------
* TieredMergePolicy and the various subtypes of LogMergePolicy no longer have
an explicit "setUseCompoundFile" method. Instead the behavior of new
segments is determined by the IndexWriter configuration, and the MergePolicy
is only consulted to determine if merge segements should use the compound
file format (based on the value of "setNoCFSRatio"). If you have explicitly
configured one of these classes using <mergePolicy> and include an init arg
like this...
<bool name="useCompoundFile">true</bool>
...this will now be treated as if you specified...
<useCompoundFile>true</useCompoundFile>
...directly on the <indexConfig> (overriding any value already set using that
syntax) and a warning will be logged to updated your configuration. Users
with an explicitly declared <mergePolicy> are encouraged to review the
current javadocs for their MergePolicy subclass and review their configured
options carefully. See SOLR-4941, SOLR-4934 and LUCENE-5038 for more
information.

* SOLR-4778: The signature of LogWatcher.registerListener has changed, from
(ListenerConfig, CoreContainer) to (ListenerConfig). Users implementing their
own LogWatcher classes will need to change their code accordingly.
CT: Add to any upgrade notes.
* LUCENE-5063: ByteField and ShortField have been deprecated and will be removed
in 5.0. If you are still using these field types, you should migrate your
fields to TrieIntField.

> Solr Ref Guide updates for Solr 4.4
> -----------------------------------

> Key: SOLR-5036

> Project: Solr
> Issue Type: Improvement
> Components: documentation
> Reporter: Cassandra Targett
> Fix For: 4.4

>
> In response to Hoss' email about updating the Solr Ref Guide, I thought it
> would be helpful if I went through the CHANGES.txt file and noted what I
> think might need an update (or a new page) and what pages should be reviewed
> for each change. I hope this helps those who aren't yet fully versed with the
> way it's organized.
> I commented on every item in CHANGES.txt, so I'll post my suggestions in a
> couple of comments. Many items (like bug fixes) don't really need updates,
> but more eyes on that would be helpful.
