Dear Wiki user,

The "ReleaseNote41" page has been changed by SteveRowe:
http://wiki.apache.org/solr/ReleaseNote41?action=diff&rev1=1&rev2=2

  
  Solr 4.1 Release Highlights:
  
-  * TODO
+ SolrCloud enhancements (see http://wiki.apache.org/solr/SolrCloud):
+ * Collection specific document routing:
+   - The "compositeId" router is the default for collections with hash
+     based routing (i.e. when numShards=N is specified on collection
+     creation).
+   - Documents with ids sharing the same domain/prefix, e.g.
+     'customerB!', will be routed to the same shard, allowing for
+     efficient querying.  At query time, one can specify a "shard.keys"
+     parameter that lists what shards the query should cover.
+   - Collections that do not specify numShards at collection creation
+     time use custom sharding and default to the "implicit" router.
+     Document updates received by a shard will be indexed to that shard,
+     unless a "_shard_" parameter or document field names a different
+     shard.
+ * Allow creating more than one shard per instance with the Collection
+   API.
+ * Allow access to the collections API through CloudSolrServer without
+   referencing an existing collection.
+ * Collection API: Support for specifying a list of Solr addresses to
+   spread a new collection across.
+ * New and imroved auto host detection strategy.
+ 
+ New features:
+ * The majority of Solr's features, including replication, now work with
+   custom Directory and DirectoryFactory implementations.
+ * Indexed term offsets, specifiable via a 'storeOffsetsWithPositions'
+   flag on field definitions in the schema.  Useful for highlighters.
+ * Solr QParsers may now be directly invoked in the lucene query syntax
+   without the _query_ magic field hack.
+   Example: foo AND {!term f=myfield v=$qq}
+ * Directory IO rate limiting based on the IO context.
+ * Distributed search support for MoreLikeThis.
+ * Multi-core: On-demand core loading and LRU-based core unloading after
+   reaching a user-specified maximum number.
+ * The new Solr 4 spatial fields now work with the {!geofilt} and {!bbox}
+   query parsers. The score local-param works too.
+ * Extra statistics to RequestHandlers - 5 & 15-minute reqs/sec rolling
+   averages; median, 75th, 95th, 99th, 99.9th percentile request times.
+ * PostingsHighlighter support (see
+   http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html) 
+ 
+ Admin UI improvements:
+ * Deleted documents are calculated/displayed.
+ * Admin Cores UI now redirects to newly created core details
+ * Replication Icon on Dashboard now reflects Master-/Slave- State 
+ * Core creation and deletion now updates the main/left list of cores 
+ * Enhanced readability of XML query response display in Query UI 
+ * Many improvements to DataImportHandler UI 
+ * Allow multiple Items to stay open on Plugins-Page 
+ 
+ Solr 4.1 also includes numerous optimizations and bugfixes.
