James it looks like this merge went awry? Usually I just 'svn revert'
the CHANGES.txt files and add the line manually for these bugfix
branches.

> +----------------------
> +
> +* The Lucene index format has changed and as a result, once you upgrade,

> +  you attempt to set this configuration option at all. (see SOLR-1846)
> +
> +* The default logic for the 'mm' param of the 'dismax' QParser has
> +  been changed.  If no 'mm' param is specified (either in the query,
> +  or as a default in solrconfig.xml) then the effective value of the

> +  If q.op is effectively "OR" then mm=0%.  Users who wish to force the
> +  legacy behavior should set a default value for the 'mm' param in

> +
> +* The VelocityResponseWriter is no longer built into the core.  Its JAR and

> +
> +* The update request parameter to choose Update Request Processor Chain is

> +
> +* Two of the SolrServer subclasses in SolrJ were renamed/replaced.

> +* Due to low level changes to support SolrCloud, the uniqueKey field can no
> +  longer be populated via <copyField/> or <field default=...> in the
> +  schema.xml.  Users wishing to have Solr automatically generate a uniqueKey
> +  value when adding documents should instead use an instance of

> +  SOLR-2796 for more details.

> +Detailed Change List
> +----------------------
> +
> +New Features
> +----------------------
> +
> +* SOLR-3272: Solr filter factory for MorfologikFilter (Polish lemmatisation).
> +  (Rafał Kuć via Dawid Weiss, Steven Rowe, Uwe Schindler).
> +
> +* SOLR-571: The autowarmCount for LRUCaches (LRUCache and FastLRUCache) now
> +  supports "percentages" which get evaluated  relative the current size of
> +  the cache when warming happens.
> +  (Tomas Fernandez Lobbe and hossman)
> +
> +* SOLR-1932: New relevancy function queries: termfreq, tf, docfreq, idf
> +  norm, maxdoc, numdocs. (yonik)
> +
> +* SOLR-1665: Add debug component options for timings, results and query info only (gsingers, hossman, yonik)
> +
> +* SOLR-2112: Solrj API now supports streaming results. (ryan)
> +
> +* SOLR-792: Adding PivotFacetComponent for Hierarchical faceting
> +  (ehatcher, Jeremy Hinegardner, Thibaut Lassalle, ryan)
> +
> +* LUCENE-2507, SOLR-2571, SOLR-2576: Added DirectSolrSpellChecker, which uses Lucene's
> +  DirectSpellChecker to retrieve correction candidates directly from the term dictionary using
> +  levenshtein automata.  (James Dyer, rmuir)
> +
> +* SOLR-1873, SOLR-2358: SolrCloud - added shared/central config and core/shard management via zookeeper,
> +  built-in load balancing, and distributed indexing.
> +  (Jamie Johnson, Sami Siren, Ted Dunning, yonik, Mark Miller)
> +  Additional Work:
> +  - SOLR-2324: SolrCloud solr.xml parameters are not persisted by CoreContainer.
> +    (Massimo Schiavon, Mark Miller)
> +  - SOLR-2287: Allow users to query by multiple, compatible collections with SolrCloud.
> +    (Soheb Mahmood, Alex Cowell, Mark Miller)
> +  - SOLR-2622: ShowFileRequestHandler does not work in SolrCloud mode.
> +    (Stefan Matheis, Mark Miller)
> +  - SOLR-3108: Error in SolrCloud's replica lookup code when replica's are hosted in same Solr instance.
> +    (Bruno Dumon, Sami Siren, Mark Miller)
> +  - SOLR-3080: Remove shard info from zookeeper when SolrCore is explicitly unloaded.
> +    (yonik, Mark Miller, siren)
> +  - SOLR-3437: Recovery issues a spurious commit to the cluster. (Trym R. Møller via Mark Miller)
> +  - SOLR-2822: Skip update processors already run on other nodes (hossman)
> +
> +* SOLR-1566: Transforming documents in the ResponseWriters.  This will allow
> +  for more complex results in responses and open the door for function queries
> +  as results.
> +  (ryan with patches from grant, noble, cmale, yonik, Jan Høydahl,
> +  Arul Kalaipandian, Luca Cavanna, hossman)
> +  - SOLR-2037: Thanks to SOLR-1566, documents boosted by the QueryElevationComponent
> +    can be marked as boosted.  (gsingers, ryan, yonik)
> +
> +* SOLR-2396: Add CollationField, which is much more efficient than
> +  the Solr 3.x CollationKeyFilterFactory, and also supports
> +  Locale-sensitive range queries. (rmuir)
> +
> +* SOLR-2338: Add support for using <similarity/> in a schema's fieldType,
> +  for customizing scoring on a per-field basis. (hossman, yonik, rmuir)
> +
> +* SOLR-2335: New 'field("...")' function syntax for referring to complex
> +  field names (containing whitespace or special characters) in functions.
> +
> +* SOLR-2383: /browse improvements: generalize range and date facet display
> +  (Jan Høydahl via yonik)
> +
> +* SOLR-2272: Pseudo-join queries / filters.  Examples:
> +  - To restrict to the set of parents with at least one blue-eyed child:
> +      fq={!join from=parent to=name}eyes:blue
> +  - To restrict to the set of children with at least one blue-eyed parent:
> +      fq={!join from=name to=parent}eyes:blue
> +  (yonik)
> +
> +* SOLR-1942: Added the ability to select postings format per fieldType in schema.xml
> +  as well as support custom Codecs in solrconfig.xml.
> +  (simonw via rmuir)
> +
> +* SOLR-2136: Boolean type added to function queries, along with
> +  new functions exists(), if(), and(), or(), xor(), not(), def(),
> +  and true and false constants. (yonik)
> +
> +* SOLR-2491: Add support for using spellcheck collation in conjunction
> +  with grouping. Note that the number of hits returned for collations
> +  is the number of ungrouped hits.  (James Dyer via rmuir)
> +
> +* SOLR-1298: Return FunctionQuery as pseudo field.  The solr 'fl' param
> +  now supports functions.  For example:  fl=id,sum(x,y) -- NOTE: only
> +  functions with fast random access are reccomended. (yonik, ryan)
> +
> +* SOLR-705: Optionally return shard info with each document in distributed
> +  search.  Use fl=id,[shard]  to return the shard url.  (ryan)
> +
> +* SOLR-2417: Add explain info directly to return documents using
> +  ?fl=id,[explain] (ryan)
> +
> +* SOLR-2533: Converted ValueSource.ValueSourceSortField over to new rewriteable Lucene
> +  SortFields.  ValueSourceSortField instances must be rewritten before they can be used.
> +  This is done by SolrIndexSearcher when necessary. (Chris Male).
> +
> +* SOLR-2193, SOLR-2565: You may now specify a 'soft' commit when committing. This will
> +  use Lucene's NRT feature to avoid guaranteeing documents are on stable storage in exchange
> +  for faster reopen times. There is also a new 'soft' autocommit tracker that can be
> +  configured. (Mark Miller, Robert Muir)
> +
> +* SOLR-2399: Updated Solr Admin interface.  New look and feel with per core administration
> +  and many new options.  (Stefan Matheis via ryan)
> +
> +* SOLR-1032: CSV handler now supports "literal.field_name=value" parameters.
> +  (Simon Rosenthal, ehatcher)
> +
> +* SOLR-2656: realtime-get, efficiently retrieves the latest stored fields for specified
> +  documents, even if they are not yet searchable (i.e. without reopening a searcher)
> +  (yonik)
> +
> +* SOLR-2703: Added support for Lucene's "surround" query parser. (Simon Rosenthal, ehatcher)
> +
> +* SOLR-2754: Added factories for several ranking algorithms:
> +    - BM25SimilarityFactory: Okapi BM25
> +    - DFRSimilarityFactory: Divergence from Randomness models
> +    - IBSimilarityFactory: Information-based models
> +    - LMDirichletSimilarity: LM with Dirichlet smoothing
> +    - LMJelinekMercerSimilarity: LM with Jelinek-Mercer smoothing
> +  (David Mark Nemeskey, Robert Muir)
> +
> +* SOLR-2134 Trie* fields should support sortMissingLast=true, and deprecate Sortable* Field Types
> +  (Ryan McKinley, Mike McCandless, Uwe Schindler, Erick Erickson)
> +
> +* SOLR-2438 added MultiTermAwareComponent to the various classes to allow automatic lowercasing
> +  for multiterm queries (wildcards, regex, prefix, range, etc). You can now optionally specify a
> +  "multiterm" analyzer in our schema.xml, but Solr should "do the right thing" if you don't
> +  specify <analyzer type="multiterm"> (Pete Sturge Erick Erickson, Mentoring from Seeley and Muir)
> +
> +* SOLR-2481: Add support for commitWithin in DataImportHandler (Sami Siren via yonik)
> +
> +* SOLR-2992: Add support for IndexWriter.prepareCommit() via prepareCommit=true
> +  on update URLs. (yonik)
> +
> +* SOLR-2906: Added LFU cache options to Solr. (Shawn Heisey via Erick Erickson)
> +
> +* SOLR-3069: Ability to add openSearcher=false to not open a searcher when doing
> +  a hard commit.  commitWithin now only invokes a softCommit. (yonik)
> +
> +* SOLR-2802: New FieldMutatingUpdateProcessor and Factory to simplify the
> +  development of UpdateProcessors that modify field values of documents as
> +  they are indexed. Also includes several useful new implementations:
> +    - RemoveBlankFieldUpdateProcessorFactory
> +    - TrimFieldUpdateProcessorFactory
> +    - HTMLStripFieldUpdateProcessorFactory
> +    - RegexReplaceProcessorFactory
> +    - FieldLengthUpdateProcessorFactory
> +    - ConcatFieldUpdateProcessorFactory
> +    - FirstFieldValueUpdateProcessorFactory
> +    - LastFieldValueUpdateProcessorFactory
> +    - MinFieldValueUpdateProcessorFactory
> +    - MaxFieldValueUpdateProcessorFactory
> +    - TruncateFieldUpdateProcessorFactory
> +    - IgnoreFieldUpdateProcessorFactory
> +  (hossman, janhoy)
> +
> +* SOLR-3120: Optional post filtering for spatial queries bbox and geofilt
> +  for LatLonType. (yonik)
> +
> +* SOLR-2459: Expose LogLevel selection with a RequestHandler rather then servlet
> +  (Stefan Matheis, Upayavira, ryan)
> +
> +* SOLR-3134: Include shard info in distributed response when shards.info=true
> +  (Russell Black, ryan)
> +
> +* SOLR-2898: Support grouped faceting. (Martijn van Groningen)
> +  Additional Work:
> +  - SOLR-3406: Extended grouped faceting support to facet.query and facet.range parameters.
> +               (David Boychuck, Martijn van Groningen)
> +
> +* SOLR-2949: QueryElevationComponent is now supported with distributed search.
> +  (Mark Miller, yonik)
> +
> +* SOLR-3221: Added the ability to directly configure aspects of the concurrency
> + and thread-pooling used within distributed search in solr. This allows for finer
> + grained controlled and can be tuned by end users to target their own specific
> + requirements. This builds on the work of the HttpCommComponent and uses the same configuration
> + block to configure the thread pool. The default configuration has
> + the same behaviour as solr 3.5, favouring throughput over latency. More
> + information can be found on the wiki (http://wiki.apache.org/solr/SolrConfigXml) (Greg Bowyer)
> +
> +* SOLR-3278: Negative boost support to the Extended Dismax Query Parser Boost Query (bq).
> +  (James Dyer)
> +
> +* SOLR-3255: OpenExchangeRates.Org Exchange Rate Provider for CurrencyField (janhoy)
> +
> +* SOLR-3358: Logging events are captured and available from the /admin/logging
> +  request handler. (ryan)
> +
> +* SOLR-1535: PreAnalyzedField type provides a functionality to index (and optionally store)
> +  field content that was already processed and split into tokens using some external processing
> +  chain. Serialization format is pluggable, and defaults to JSON. (ab)
> +
> +* SOLR-3363: Consolidated Exceptions in Analysis Factories so they only throw
> +  InitalizationExceptions (Chris Male)
> +
> +* SOLR-2690: New support for a "TZ" request param which overrides the TimeZone
> +  used when rounding Dates in DateMath expressions for the entire request
> +  (all date range queries and date faceting is affected).  The default TZ
> +  is still UTC.  (David Schlotfeldt, hossman)
> +
> +* SOLR-3402: Analysis Factories are now configured with their Lucene Version
> +  throw setLuceneMatchVersion, rather than through the Map passed to init.
> +  Parsing and simple error checking for the Version is now done inside
> +  the code that creates the Analysis Factories. (Chris Male)
> +
> +* SOLR-3178: Optimistic locking.  If a _version_ is provided with an update
> +  that does not match the version in the index, an HTTP 409 error (Conflict)
> +  will result.  (Per Steffensen, yonik)
> +
> +* SOLR-139: Updateable documents.  JSON Example:
> +  {"id":"mydoc", "f1":{"set":10}, "f2":{"add":20}}  will result in field "f1"
> +  being set to 10, "f2" having an additional value of 20 added, and all
> +  other existing fields unchanged.  All source fields must be stored for
> +  this feature to work correctly.  (Ryan McKinley, Erik Hatcher, yonik)
> +
> +* SOLR-2857: Support XML,CSV,JSON, and javabin in a single RequestHandler and
> +  choose the correct ContentStreamLoader based on Content-Type header.  This
> +  also deprecates the existing [Xml,JSON,CSV,Binary,Xslt]UpdateRequestHandler.
> +  (ryan)
> +
> +* SOLR-2585: Context-Sensitive Spelling Suggestions & Collations.  This adds support
> +  for the "spellcheck.alternativeTermCount" & "spellcheck.maxResultsForSuggest"
> +  parameters, letting users receive suggestions even when all the queried terms
> +  exist in the dictionary.  This differs from "spellcheck.onlyMorePopular" in
> +  that the suggestions need not consist entirely of terms with a greater document
> +  frequency than the queried terms. (James Dyer)
> +
> +* SOLR-2058: Edismax query parser to allow "phrase slop" to be specified per-field
> +  on the pf/pf2/pf3 parameters using optional "FieldName~slop^boost" syntax.  The
> +  prior "FieldName^boost" syntax is still accepted.  In such cases the value on the
> +  "ps" parameter serves as the default slop.  (Ron Mayer via James Dyer)
> +
> +* SOLR-3495: New UpdateProcessors have been added to create default values for
> +  configured fields.  These works similarly to the <field default="..."/>
> +  option in schema.xml, but are applied in the UpdateProcessorChain, so they
> +  may be used prior to other UpdateProcessors, or to generate a uniqueKey field
> +  value when using the DistributedUpdateProcessor (ie: SolrCloud)
> +    TimestampUpdateProcessorFactory
> +    UUIDUpdateProcessorFactory
> +    DefaultValueUpdateProcessorFactory
> +  (hossman)
> +
> +* SOLR-2993: Add WordBreakSolrSpellChecker to offer suggestions by combining adjacent
> +  query terms and/or breaking terms into multiple words.  This spellchecker can be
> +  configured with a traditional checker (ie: DirectSolrSpellChecker).  The results
> +  are combined and collations can contain a mix of corrections from both spellcheckers.
> +  (James Dyer)
> +
> +* SOLR-3508: Simplify JSON update format for deletes as well as allow
> +  version specification for optimistic locking.  Examples:
> +    - {"delete":"myid"}
> +    - {"delete":["id1","id2","id3"]}
> +    - {"delete":{"id":"myid", "_version_":123456789}}
> +  (yonik)
> +
> +* SOLR-3211:  Allow parameter overrides in conjunction with "spellcheck.maxCollationTries".
> +  To do so, use parameters starting with "spellcheck.collateParam."  For instance, to
> +  override the "mm" parameter, specify "spellcheck.collateParam.mm".  This is helpful
> +  in cases where testing spellcheck collations for result counts should use different
> +  parameters from the main query (James Dyer)
> +
> +* SOLR-2599: CloneFieldUpdateProcessorFactory provides similar functionality
> +  to schema.xml's <copyField/> declaration but as an update processor that can
> +  be combined with other processors in any order. (Jan Høydahl & hossman)
> +
> +* SOLR-3351: eDismax: ps2 and ps3 params (janhoy)
> +
> +* SOLR-3542: Add WeightedFragListBuilder for FVH and set it to default fragListBuilder
> +  in example solrconfig.xml. (Sebastian Lutze, koji)
> +
> +* SOLR-2396: Add ICUCollationField to contrib/analysis-extras, which is much
> +  more efficient than the Solr 3.x ICUCollationKeyFilterFactory, and also
> +  supports Locale-sensitive range queries.  (rmuir)
> +
> +
> +Optimizations
> +----------------------
> +
> +* SOLR-1875: Per-segment field faceting for single valued string fields.
> +  Enable with facet.method=fcs, control the number of threads used with
> +  the "threads" local param on the facet.field param.  This algorithm will
> +  only be faster in the presence of rapid index changes.  (yonik)
> +
> +* SOLR-1904: When facet.enum.cache.minDf > 0 and the base doc set is a
> +  SortedIntSet, convert to HashDocSet for better performance. (yonik)
> +
> +* SOLR-2092: Speed up single-valued and multi-valued "fc" faceting. Typical
> +  improvement is 5%, but can be much greater (up to 10x faster) when facet.offset
> +  is very large (deep paging). (yonik)
> +
> +* SOLR-2193, SOLR-2565: The default Solr update handler has been improved so
> +  that it uses fewer locks, keeps the IndexWriter open rather than closing it
> +  on each commit (ie commits no longer wait for background merges to complete),
> +  works with SolrCore to provide faster 'soft' commits, and has an improved API
> +  that requires less instanceof special casing. (Mark Miller, Robert Muir)
> +  Additional Work:
> +  - SOLR-2697: commit and autocommit operations don't reset
> +    DirectUpdateHandler2.numDocsPending stats attribute.
> +    (Alexey Serba, Mark Miller)
> +
> +* SOLR-2950: The QueryElevationComponent now avoids using the FieldCache and looking up
> +  every document id (gsingers, yonik)
> +
> +Bug Fixes
> +----------------------
> +* SOLR-3139: Make ConcurrentUpdateSolrServer send UpdateRequest.getParams()
> +  as HTTP request params (siren)
> +
> +* SOLR-3165: Cannot use DIH in Solrcloud + Zookeeper (Alexey Serba,
> +  Mark Miller, siren)
> +
> +* SOLR-3068: Occasional NPE in ThreadDumpHandler (siren)
> +
> +* SOLR-2762: FSTLookup could return duplicate results or one results less
> +  than requested. (David Smiley, Dawid Weiss)
> +
> +* SOLR-2741: Bugs in facet range display in trunk (janhoy)
> +
> +* SOLR-1908: Fixed SignatureUpdateProcessor to fail to initialize on
> +  invalid config.  Specifically: a signatureField that does not exist,
> +  or overwriteDupes=true with a signatureField that is not indexed.
> +  (hossman)
> +
> +* SOLR-1824: IndexSchema will now fail to initialize if there is a
> +  problem initializing one of the fields or field types. (hossman)
> +
> +* SOLR-1928: TermsComponent didn't correctly break ties for non-text
> +  fields sorted by count. (yonik)
> +
> +* SOLR-2107: MoreLikeThisHandler doesn't work with alternate qparsers. (yonik)
> +
> +* SOLR-2108: Fixed false positives when using wildcard queries on fields with reversed
> +  wildcard support. For example, a query of *zemog* would match documents that contain
> +  'gomez'.  (Landon Kuhn via Robert Muir)
> +
> +* SOLR-1962: SolrCore#initIndex should not use a mix of indexPath and newIndexPath (Mark Miller)
> +
> +* SOLR-2275: fix DisMax 'mm' parsing to be tolerant of whitespace
> +  (Erick Erickson via hossman)
> +
> +* SOLR-2193, SOLR-2565, SOLR-2651: SolrCores now properly share IndexWriters across SolrCore reloads.
> +  (Mark Miller, Robert Muir)
> +  Additional Work:
> +  - SOLR-2705: On reload, IndexWriterProvider holds onto the initial SolrCore it was created with.
> +    (Yury Kats, Mark Miller)
> +
> +* SOLR-2682: Remove addException() in SimpleFacet. FacetComponent no longer catches and embeds
> +  exceptions occurred during facet processing, it throws HTTP 400 or 500 exceptions instead. (koji)
> +
> +* SOLR-2654: Directorys used by a SolrCore are now closed when they are no longer used.
> +  (Mark Miller)
> +
> +* SOLR-2854: Now load URL content stream data (via stream.url) when called for during request handling,
> +  rather than loading URL content streams automatically regardless of use.
> +  (David Smiley and Ryan McKinley via ehatcher)
> +
> +* SOLR-2829: Fix problem with false-positives due to incorrect
> +  equals methods. (Yonik Seeley, Hossman, Erick Erickson.
> +  Marc Tinnemeyer caught the bug)
> +
> +* SOLR-2848: Removed 'instanceof AbstractLuceneSpellChecker' hacks from distributed spellchecking code,
> +  and added a merge() method to SolrSpellChecker instead. Previously if you extended SolrSpellChecker
> +  your spellchecker would not work in distributed fashion.  (James Dyer via rmuir)
> +
> +* SOLR-2509: StringIndexOutOfBoundsException in the spellchecker collate when the term contains
> +  a hyphen. (Thomas Gambier caught the bug, Steffen Godskesen did the patch, via Erick Erickson)
> +
> +* SOLR-1730: Made it clearer when a core failed to load as well as better logging when the
> +  QueryElevationComponent fails to properly initialize (gsingers)
> +
> +* SOLR-1520: QueryElevationComponent now supports non-string ids (gsingers)
> +
> +* SOLR-3037: When using binary format in solrj the codec screws up parameters
> +  (Sami Siren, Jörg Maier  via yonik)
> +
> +* SOLR-3062: A join in the main query was not respecting any filters pushed
> +  down to it via acceptDocs since LUCENE-1536. (Mike Hugo, yonik)
> +
> +* SOLR-3214: If you use multiple fl entries rather than a comma separated list, all but the first
> +  entry can be ignored if you are using distributed search. (Tomas Fernandez Lobbe via Mark Miller)
> +
> +* SOLR-3352: eDismax: pf2 should kick in for a query with 2 terms (janhoy)
> +
> +* SOLR-3361: ReplicationHandler "maxNumberOfBackups" doesn't work if backups are triggered on commit
> +  (James Dyer, Tomas Fernandez Lobbe)
> +
> +* SOLR-2605: fixed tracking of the 'defaultCoreName' in CoreContainer so that
> +  CoreAdminHandler could return consistent information regardless of wether
> +  there is a a default core name or not. (steffkes, hossman)
> +
> +* SOLR-3370: fixed CSVResponseWriter to respect globs in the 'fl' param
> +  (Keith Fligg via hossman)
> +
> +* SOLR-3436: Group count incorrect when not all shards are queried in the second
> +  pass. (Francois Perron, Martijn van Groningen)
> +
> +* SOLR-3454: Exception when using result grouping with main=true and using
> +  wt=javabin. (Ludovic Boutros, Martijn van Groningen)
> +
> +* SOLR-3446: Better errors when PatternTokenizerFactory is configured with
> +  an invalid pattern, and include the 'name' whenever possible in plugin init
> +  error messages. (hossman)
> +
> +* LUCENE-4075: Cleaner path usage in TestXPathEntityProcessor
> +  (Greg Bowyer via hossman)
> +
> +* SOLR-2923: IllegalArgumentException when using useFilterForSortedQuery on an
> +  empty index. (Adrien Grand via Mark Miller)
> +
> +* SOLR-2352: Fixed TermVectorComponent so that it will not fail if the fl
> +  param contains globs or psuedo-fields (hossman)
> +
> +* SOLR-3541: add missing solrj dependencies to binary packages.
> +  (Thijs Vonk via siren)
> +
> +* SOLR-3522: fixed parsing of the 'literal()' function (hossman)
> +
> +* SOLR-3548: Fixed a bug in the cachability of queries using the {!join}
> +  parser or the strdist() function, as well as some minor improvements to
> +  the hashCode implementation of {!bbox} and {!geofilt} queries.
> +  (hossman)
> +
> +* SOLR-3470: contrib/clustering: custom Carrot2 tokenizer and stemmer factories
> +  are respected now (Stanislaw Osinski, Dawid Weiss)
> +
> +* SOLR-3430: Added a new DIH test against a real SQL database.  Fixed problems
> +  revealed by this new test related to  the expanded cache support added to
> +  3.6/SOLR-2382 (James Dyer)
> +
> +* SOLR-1958: When using the MailEntityProcessor, import would fail if
> +  fetchMailsSince was not specified. (Max Lynch via James Dyer)
> +
> +
> +Other Changes
> +----------------------
> +
> +* SOLR-1846: Eliminate support for the abortOnConfigurationError
> +  option.  It has never worked very well, and in recent versions of
> +  Solr hasn't worked at all.  (hossman)
> +
> +* SOLR-1889: The default logic for the 'mm' param of DismaxQParser and
> +  ExtendedDismaxQParser has been changed to be determined based on the
> +  effective value of the 'q.op' param (hossman)
> +
> +* SOLR-1946: Misc improvements to the SystemInfoHandler: /admin/system
> +  (hossman)
> +
> +* SOLR-2289: Tweak spatial coords for example docs so they are a bit
> +  more spread out (Erick Erickson via hossman)
> +
> +* SOLR-2288: Small tweaks to eliminate compiler warnings.  primarily
> +  using Generics where applicable in method/object declatations, and
> +  adding @SuppressWarnings("unchecked") when appropriate (hossman)
> +
> +* SOLR-2375: Suggester Lookup implementations now store trie data
> +  and load it back on init. This means that large tries don't have to be
> +  rebuilt on every commit or core reload. (ab)
> +
> +* SOLR-2413: Support for returning multi-valued fields w/o <arr> tag
> +  in the XMLResponseWriter was removed.  XMLResponseWriter only
> +  no longer work with values less then 2.2 (ryan)
> +
> +* SOLR-2423: FieldType argument changed from String to Object
> +  Conversion from SolrInputDocument > Object > Fieldable is now managed
> +  by FieldType rather then DocumentBuilder.  (ryan)
> +
> +* SOLR-2461: QuerySenderListener and AbstractSolrEventListener are
> +  now public (hossman)
> +
> +* LUCENE-2995: Moved some spellchecker and suggest APIs to modules/suggest:
> +  HighFrequencyDictionary, SortedIterator, TermFreqIterator, and the
> +  suggester APIs and implementations. (rmuir)
> +
> +* SOLR-2576: Remove deprecated SpellingResult.add(Token, int).
> +  (James Dyer via rmuir)
> +
> +* LUCENE-3232: Moved MutableValue classes to new 'common' module. (Chris Male)
