+# Lucene.NET 4.8.0-beta00014 Release Notes
+
+---
+
+> This release contains bug fixes and minor performance improvements
+
+## Change Log
+
+### Breaking Changes
+* [#424](https://github.com/apache/lucenenet/pull/424) - Deprecated
`TaskMergeScheduler`, a merge scheduler that was added to support .NET Standard
1.x
+* [#424](https://github.com/apache/lucenenet/pull/424) -
`Lucene.Net.TestFramework`: Removed the public
`LuceneTestCase.ConcurrentMergeSchedulerFactories` class
+
+### Bugs
+* [#405](https://github.com/apache/lucenenet/pull/405),
[#415](https://github.com/apache/lucenenet/pull/415) -
`Lucene.Net.Index.DocTermOrds`: Fixed issue with enumerator
(`OrdWrappedTermsEnum`) incorrectly returning `true` when the value is `null`.
+* [#427](https://github.com/apache/lucenenet/pull/427) -
`Lucene.Net.Analysis.Common`: Fixed `TestRollingCharBuffer::Test()` to prevent
out of memory exceptions when running with `Verbose` enabled
+* [#434](https://github.com/apache/lucenenet/pull/434),
[#418](https://github.com/apache/lucenenet/pull/418) - Hunspell affixes' file
parsing corrupts some affixes' conditions
+* [#434](https://github.com/apache/lucenenet/pull/434),
[#419](https://github.com/apache/lucenenet/pull/419) - `HunspellStemFilter`
does not work with zero affix
+* [#439](https://github.com/apache/lucenenet/pull/439) -
`Lucene.Net.Facet.Taxonomy.CachedOrdinalsReader`: Fixed synchronization issue
between adding new items to the cache and reading `RamBytesUsed` method
+* [#439](https://github.com/apache/lucenenet/pull/439),
[#417](https://github.com/apache/lucenenet/pull/417),
[#319](https://github.com/apache/lucenenet/pull/319) -
`Lucene.Net.Spatial.Util.ShapeFieldCacheProvider`: Fixed atomicity issue with
loading the cache by using `Lazy<T>`.
+* [#441](https://github.com/apache/lucenenet/pull/441) - `
Lucene.Net.TestFramework.Support.Confguration.TestConfigurationFactory`: Use
`Lazy<T>` to ensure the `configurationCache.GetOrAdd()` factory is atomic.
+* [#441](https://github.com/apache/lucenenet/pull/441) -
`Lucene.Net.TestFramework.Search.ShardSearchingTestBase: Fixed possible
`KeyNotFoundException` when getting the value from `collectionStatisticsCache`
+* [#441](https://github.com/apache/lucenenet/pull/441),
[#417](https://github.com/apache/lucenenet/pull/417),
[#319](https://github.com/apache/lucenenet/pull/319) -
`Lucene.Net.Spatial.Prefix.PrefixTreeFactory`: Use `Lazy<T>` in
`ConcurrentDictionary` to make the `valueFactory` atomic.
+* [#443](https://github.com/apache/lucenenet/pull/443) -
`Lucene.Net.Benchmark.ByTask.Feeds.SpatialDocMaker: Since `Dictionary<TKey,
TValue>.this[key]` is not marked virtual in .NET, subclassing
`Dictionary<string, string>` is not a valid approach. So we implement
`IDictionary<string, string>` instead.
+* [#416](https://github.com/apache/lucenenet/pull/416) - CLI Documentation
issue - environment variable token not replaced.
+* [#450](https://github.com/apache/lucenenet/pull/450) - `Lucene.Net.Facet` -
Reverted locking in to the state it was in Lucene 4.8.1, however we are still
making use of `ReaderWriterLockSlim` to improve read performance of caches.
Also, removed the 1 second lock timeout from `Cl2oTaxonomyWriterCache`.
+

+* [#435](https://github.com/apache/lucenenet/pull/435),

`Lucene.Net.Tests.Expressions`
+* [#438](https://github.com/apache/lucenenet/pull/438) - Don't insert extra
newline in TFIDFSim's score explanation (this minor change had already been
done to Lucene 5.0, so we are back-porting it to 4.8.0)
+* [#439](https://github.com/apache/lucenenet/pull/439) -
`Lucene.Net.Util.VirtualMethod`: Removed unnecessary call to `Convert.ToInt32()`
+* [#439](https://github.com/apache/lucenenet/pull/439) -
`Lucene.Net.Util.AttributeSource`: Restored comment from Lucene indicating it
doesn't matter if multiple threads compete to populate the
`ConditionalWeakTable`.
+* [#440](https://github.com/apache/lucenenet/pull/440) - **SWEEP**: Reviewed
catch blocks and made improvements to preserve stack details.
+* [#441](https://github.com/apache/lucenenet/pull/441),
[#417](https://github.com/apache/lucenenet/pull/417) -
`Lucene.Net.Analysis.OpenNLP.Tools.OpenNLPOpsFactory`: Simplified logic by
using `GetOrAdd()` instead of `TryGetValue`.
+* [#441](https://github.com/apache/lucenenet/pull/441) - `
Lucene.Net.TestFramework.Util` (`LuceneTestCase` + `TestUtil`): Refactored the
`CleanupTemporaryFiles()` method to be more in line with the original Java
implementation, including not allowing new files/directories to be added to the
queue concurrently with the deletion process.
+* [#441](https://github.com/apache/lucenenet/pull/441) - **PERFORMANCE:** `
Lucene.Net.Join.ToParentBlockJoinCollector`: Changed from `ConcurrentQueue<T>`
to `Queue<T>` because we are dealing with a collection declared within the same
method so there is no reason for the extra overhead.
+* [#441](https://github.com/apache/lucenenet/pull/441) - **PERFORMANCE:** `
Lucene.Net.Tests.Suggest.Spell.TestSpellChecker`: Replaced `ConcurrentBag<T>`
with ConcurrentQueue<T> because we need to be sure the underlying
implementation guarantees order and the extra call to `Reverse()` was just
slowing things down.
+* [#441](https://github.com/apache/lucenenet/pull/441) - `
Lucene.Net.TestFramework.Search.ShardSearchingTestBase`: Display the contents
of the collection to the console using `Collections.ToString()`.
+* [#441](https://github.com/apache/lucenenet/pull/441) - `
Lucene.Net.Search.SearcherLifetimeManager: Added comment to indicate the reason
we use `Lazy<T>` is to make the create operation atomic.
+* [#441](https://github.com/apache/lucenenet/pull/441) - `
Directory.Build.Targets`: Added `FEATURE_DICTIONARY_REMOVE_CONTINUEENUMERATION`
so we can support this feature in .NET 5.x + when we add a target.
+* [#442](https://github.com/apache/lucenenet/pull/442) - **PERFORMANCE:**
`Lucene.Net.Search.Suggest.Fst.FSTCompletion`: Use `Stack<T>` rather than
`List<T>.Reverse()`. Also, removed unnecessary lock in
`CheckExistingAndReorder()`, as it is only used in a single thread at a time.
+* [#442](https://github.com/apache/lucenenet/pull/442) - **PERFORMANCE:**
`Lucene.Net.Search.Suggest.SortedInputEnumerator`: Removed unnecessary call to
`Reverse()` and allocation of `HashSet<T>`
+* [#444](https://github.com/apache/lucenenet/pull/444),
[#272](https://github.com/apache/lucenenet/pull/272) - **PERFORMANCE:**
`Lucene.Net.Search.FieldCacheImpl`: Reverted locking back to the state of
Lucene 4.8.0.
+* [#445](https://github.com/apache/lucenenet/pull/445) - Removed
`FEATURE_THREAD_INTERRUPT` since all supported targets now support thread
interrupts. Note also that Lucene *depends* on thread interrupts to function
properly, so disabling this feature would be invalid.
+* [#448](https://github.com/apache/lucenenet/pull/448) - **DOCS:** Added
migration guide for users migrating from Lucene.NET 3.0.3 to Lucene.NET 4.8.0.
+* [#396](https://github.com/apache/lucenenet/pull/396) - **DOCS:** Create
branching scheme to track changes in docuentation between different Lucene
versions and removed the `JavaDocToMarkdownConverter` tool from the normal
build workflow of the API docs. This frees us up to update the "namespace"
documentation with .NET-specific information and code examples.
+* Upgraded J2N NuGet package dependency to 2.0.0-beta-0012
+* Upgraded ICU4N NuGet package dependency to 60.1.0-alpha.254
+* Upgraded Morfologik.Stemming package dependency to 2.1.7-beta-0002
+
+### New Features
+* [#385](https://github.com/apache/lucenenet/pull/385),
[#362](https://github.com/apache/lucenenet/pull/362) -
`Lucene.Net.Documents.Document`: Added culture-sensitive overloads of
`GetValues()`, `Get()` and `GetStringValue()` that accept `format` and
`IFormatProvider` and implemented `IFormattable` on `Document` and
`LazyDocument`.
+* [#404](https://github.com/apache/lucenenet/pull/404) - Added `Commit()`
method to `AnalyzingInfixSuggester` (from
[LUCENE-5889](https://issues.apache.org/jira/browse/LUCENE-5889))
