Added a very substantial (3-5X) RAM reduction required to hold the terms index on opening an IndexReader. (LUCENE-2205)
Added SearcherManager to manage sharing and reopening IndexSearchers across multiple search threads. Underlying IndexReader instances are safely closed if not referenced anymore. (LUCENE-3445, LUCENE-3558)
Added SearcherLifetimeManager which safely provides a consistent view of the index across multiple requests (e.g. paging/drilldown). (LUCENE-3558, LUCENE-3486)
Added NGramPhraseQuery that speeds up phrase queries 30-50% when n-gram analysis is used. (LUCENE-3426)
Improvements to vector highlighting: support for more queries such as wildcards and boundary analysis for generated snippets. (LUCENE-1824, LUCENE-1889)

Highlights of the Solr release include:

Bug fixes and improvements from Apache Lucene 3.5.0, including a very substantial (3-5X) RAM reduction required to hold the terms index on opening an IndexReader. (LUCENE-2205)
Added support for distributed result grouping. (SOLR-2066, SOLR-2776)
Added support for Hunspell stemmer TokenFilter supporting stemming for 99 languages. (SOLR-2769)
A new contrib module "langid" adds language identification capabilities as an Update Processor, using Tika's LanguageIdentifier or Cybozu language-detection library (SOLR-1979)
Numeric types including Trie and date types now support sortMissingFirst/Last. (SOLR-2881)
Added hl.q parameter. It is optional and if it is specified, it overrides q parameter in Highlighter. (SOLR-1926)
Several minor bugfixes like date parsing for years from 0001-1000, ignored configurations when using QueryAnalyzer with SpellCheckComponent and many more. See CHANGES.txt entries for full details.
