+# Lucene.NET 4.8.0-beta00016 Release Notes
+
+---
+
+> This release contains several important bug fixes and performance enhancements.
+
+## Breaking Index Changes
+
+There are 2 breaking changes that may affect some users when reading indexes that were created from version 4.8.0-beta00015 and all prior 4.8.0 beta versions (not including 3.0.3).
+1. A bug was fixed in the generation of segment file names. This only affects users with more than 10 segments in their index.
+2. `Lucene.Net.Documents.DateTools` has been modified to return _milliseconds since Unix epoch_ (that is, since Jan 1, 1970 at 00:00:00 UTC) by *default* to match Java Lucene. This only affects users who explicitly use `Lucene.Net.Documents.DateTools` in their application and store the result (in .NET ticks) in their index.
+
+If you are affected by either of the above issues, it is recommended to regenerate your indexes during upgrading. However, if that is not feasible, we have provided the following workarounds.
+
+1. If you have a large index with more than 10 segments, see [#576](https://github.com/apache/lucenenet/pull/576) for details on how to enable legacy segment name support.
+2. If you are storing the result of `Lucene.Net.Documents.DateTools.StringToTime(string)` or `Lucene.Net.Documents.DateTools.Round(long)` (a `long`) in your index, you are storing .NET ticks. There are now optional parameters `inputRepresentation` and `outputRepresentation` on these methods to specify whether the `long` value represents .NET ticks, .NET ticks as milliseconds, or millisenonds since the Unix epoch. To exactly match version 4.8.0-beta00015 and prior (including prior major v [...]
+ - `Lucene.Net.Documents.DateTools.StringToTime(string, NumericRepresentation)` should specify `NumericRepresentation.TICKS` for `outputRepresentation`.
+ - `Lucene.Net.Documents.DateTools.Round(long, NumericRepresentation, NumericRepresentation)` should specify `NumericRepresentation.TICKS_AS_MILLISECONDS` for `inputRepresentation` and `NumericRepresentation.TICKS` for `outputRepresentation`.
+
+## .NET Framework Recommendations
+
+It is recommended that all .NET Framework users migrate as soon as possible.
+
+1. In cases where `Lucene.Net.Support.WeakDictionary<TKey, TValue>` was used in .NET Framework and .NET Standard 2.0 due to missing APIs, but there is now a better solution using `Prism.Core`'s weak events in combination with `ConditionalWeakTable<TKey, TValue>`, which means memory management is handled entirely by the GC in `Lucene.Net.Index.IndexReader`, `Lucene.Net.Search.FieldCacheImpl`, `Lucene.Net.Search.CachingWrappingFilter` and `Lucene.Net.Facet.Taxonomy.CachedOrdinalsReader`. S [...]
+2. All known issues with loss of floating-point precision on .NET Framework x86 have been fixed.
+
+## Change Log
+
+### Breaking Changes
+* [#547](https://github.com/apache/lucenenet/pull/547) - `Lucene.Net.Util.StringHelper.GOOD_FAST_HASH_SEED`: converted from a static field to a property and marked obsolete. Added a new property `GoodFastHashSeed`. Removed `SystemProperties` call to populate the value of the field, since NUnit only allows us to generate a seed per test, and we need a way to inject the seed value for repeatability.
+* [#547](https://github.com/apache/lucenenet/pull/547) - `Lucene.Net.TestFramework`: Added `LuceneSetUpFixtureBuilder` class to load either a subclass or our default instance of `LuceneTestFrameworkInitializer`. Also added `LuceneTestCase.SetUpFixture` to control initialization of `LuceneTestFrameworkInitializer` so it is only called on setup and teardown for the assembly. Added `Initialize()` method to `LuceneTestFrameworkInitializer` that *must be used* when setting factories during testing.
+* [#547](https://github.com/apache/lucenenet/pull/547) - `Lucene.Net.TestFramework.Util.LuceneTestCase`: Deprecated `GetClassType()` method and added `TestType` property
+* [#547](https://github.com/apache/lucenenet/pull/547) - `Lucene.Net.TestFramework.Util.AbstractBeforeAfterRule``: Removed `LuceneTestCase` parameter from `Before()` and `After()` methods.
+* [#551](https://github.com/apache/lucenenet/pull/551) - Changed constructors of `Lucene.Net.Util.NumberFormat` and `Lucene.Net.QueryParsers.Flexible.Standard.Config.NumberDateFormat` to accept `IFormatProvider` rather than `CultureInfo` and changed `Lucene.Net.Util.NumberFormat.Culture` property to `Lucene.Net.Util.NumberFormat.FormatProvider`.
+* [#554](https://github.com/apache/lucenenet/pull/554) - `Lucene.Net.Misc`: Made `DocFreqComparer` and `TotalTermFreqComparer` into static singletons, only accessible by the `Default` property.
+* [#428](https://github.com/apache/lucenenet/pull/428), [#429](https://github.com/apache/lucenenet/pull/429), [#570](https://github.com/apache/lucenenet/pull/570) - `Lucene.Net.Search.FieldComparer`: Redesigned implementation to use reference types for numerics (from J2N) to avoid boxing.
+* [#570](https://github.com/apache/lucenenet/pull/570) - `Lucene.Net.Search.FieldCache.IParser`: Renamed method from `TermsEnum()` to `GetTermsEnum()` to match other APIs
+* [#570](https://github.com/apache/lucenenet/pull/570) - `Lucene.Net.Queries`: `ObjectVal()` returns a `J2N.Numerics.Number`-derived type rather than a value type cast to object. Direct casts to `int`, `long`, `double`, `single`, etc. will no longer work without first casting to the `J2N.Numerics.Number`-derived type. Alternatively, use the corresponding `Convert.ToXXX()` method for the type you wish to retrieve from the object.
+* [#574](https://github.com/apache/lucenenet/pull/574) - `Lucene.Net.Suggest.Fst.FSTCompletionLookup/WFSTCompletionLookup`: Changed `Get()` to return `long?` instead of `object` to eliminate boxing/unboxing
+* [#574](https://github.com/apache/lucenenet/pull/574) - `Lucene.Net.Index.MergePolicy::FindForcedMerges()`: Removed unnecessary nullable from `FindForcedMerges()` and all `MergePolicy` subclasses
+* [#574](https://github.com/apache/lucenenet/pull/574) - `Lucene.Net.Replicator`: Changed callback signature from `Func<bool?>` to `Action`, since the return value had no semantic meaning
+* [#575](https://github.com/apache/lucenenet/pull/575) - `Lucene.Net.Index.DocValuesFieldUpdates`: Refactored so the subclasses will handle getting the values from `DocValuesFieldUpdatesIterator` or `DocValuesUpdate` via a cast rather than boxing the value. Also marked internal (as well as all members of `BufferedUpdates`), since this was not supposed to be part of the public API.
+* [#573](https://github.com/apache/lucenenet/pull/573), [#576](https://github.com/apache/lucenenet/pull/576) - Changed segment file names to match Lucene 4.8.0 and Lucene.NET 3.x
+* [#577](https://github.com/apache/lucenenet/pull/577) - `Lucene.Net.Index.SegmentInfos`: Changed `Info()` method to an indexer (.NET Convention)
+* [#580](https://github.com/apache/lucenenet/pull/580) - `Lucene.Net.Documents.DateTools` - Added `NumericRepresentation` enum to allow converting to/from long in the following formats:
+ - Unix Epoch (default): Milliseconds since Jan 1, 1970 12:00:00 AM UTC.
+ - Ticks: The raw ticks from `DateTime` or `DateTimeOffset`.
+ - Ticks as Milliseconds: This is for compatibility with prior versions of Lucene.NET (3.0.3 and 4.8.0-beta00001 - 4.8.0-beta00015). The conversion done on input values is `time * TimeSpan.TicksPerMillisecond` and the conversion to output values is `time / TimeSpan.TicksPerMillisecond`.
+
+ **The `long` return value from `Lucene.Net.Documents.DateTools.StringToTime(string, NumericRepresentation)` has been changed from `NumericRepresentation.TICKS` to `NumericRepresentation.UNIX_TIME_MILLISECONDS` by default.**
+
+ **The `long` input parameter provided to `Lucene.Net.Documents.DateTools.Round(long, NumericRepresentation, NumericRepresentation)` has been changed from `NumericRepresentation.TICKS_AS_MILLISECONDS` to `NumericRepresentation.UNIX_TIME_MILLISECONDS` by default.**
+
+ **The `long` return value from `Lucene.Net.Documents.DateTools.Round(long, NumericRepresentation, NumericRepresentation)` has changed from `NumericRepresentation.TICKS` to `NumericRepresentation.UNIX_TIME_MILLISECONDS` by default.**
+* [#580](https://github.com/apache/lucenenet/pull/580) - `Lucene.Net.Documents.DateTools` - De-nested `Resolution` enum and renamed `DateResolution`.
+* [#580](https://github.com/apache/lucenenet/pull/580) - `Lucene.Net.QueryParsers.Flexible.Standard`: Changed numeric nodes to accept and return `J2N.Numerics.Number`-derived types instead of `object`.
+* [#581](https://github.com/apache/lucenenet/pull/581) - **SWEEP:** `Lucene.Net.Util.Fst`: Changed API to use `J2N.Numerics.Int64` instead of `long?` for generic closing type as it was designed to use reference equality comparison.
+* [#581](https://github.com/apache/lucenenet/pull/581) - **SWEEP:** `Lucene.Net.Util.Fst`: Added class constraints to each generic FST type and reverted to reference equality comparisons.
+* [#581](https://github.com/apache/lucenenet/pull/581), [#279](https://github.com/apache/lucenenet/pull/279) - `Lucene.Net.Util.Fst.Int32sRefFSTEnum`: Added `MoveNext()` method and marked `Next()` method obsolete. This change had already been done to BytesRefFSTEnum, which made them inconsistent.
+* [#583](https://github.com/apache/lucenenet/pull/583) - `Lucene.Net.QueryParsers.Flexible`: Removed unnecessary nullable value types from `ConfigurationKeys` and configuration setters/getters in `StandardQueryParser`. Added `AbstractQueryConfig.TryGetValue()` method to allow retrieving value types so they can be defaulted properly.
+* [#583](https://github.com/apache/lucenenet/pull/583) - `Lucene.Net.Queries.Function.ValueSources.EnumFieldSource::ctor()` - changed `enumIntToStringMap` to accept `IDictionary<int, string>` instead of `IDictionary<int?, string>` (removed unnecessary nullable)
+* [#587](https://github.com/apache/lucenenet/pull/587) - `Lucene.Net.TestFramework.Store.MockDirectoryWrapper`: Renamed `AssertNoUnreferencedFilesOnClose` to `AssertNoUnreferencedFilesOnDispose`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial`: Upgraded to new Spatial4n NuGet package that unifies the types from Spatial4n.Core and Spatial4n.Core.NTS
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.Tree.Cell`: Renamed `m_outerInstance` > `m_spatialPrefixTree` and constructor parameter `outerInstance` > `spatialPrefixTree`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.AbstractPrefixTreeFilter.BaseTermsEnumTransverser`: renamed `m_outerInstance` > `m_filter`, constructor parameter `outerInstance` > `filter`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.AbstractPrefixTreeFilter`: De-nested `BaseTermsEnumTraverser`class
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.Tree.GeohashPrefixTree.Factory`: de-nested and renamed `GeohashPrefixTreeFactory`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.Tree.QuadPrefixTree.Factory`: de-nested and renamed `QuadPrefixTreeFactory`
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Prefix.AbstractVisitingPrefixTreeFilter`: De-nested `VisitorTemplate` class and changed protected field `m_prefixGridScanLevel` to a public property named `PrefixGridScanLevel`.
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Query`: Renamed `UnsupportedSpatialOperation` > `UnsupportedSpatialOperationException` to match .NET conventions
+
+### Bugs
+* [#363](https://github.com/apache/lucenenet/pull/363), [#534](https://github.com/apache/lucenenet/pull/534) - `Lucene.Net.Replicator.Http.HttpReplicatorTest::TestBasic()`. This was failing intermittently due to the Timeout value being set to 1 second instead of the 60 second value that was used in Java. It has been increased to the .NET default of 100 seconds.
+* [#363](https://github.com/apache/lucenenet/pull/363), [#534](https://github.com/apache/lucenenet/pull/534) - `Lucene.Net.Replicator.IndexAndTaxonomyReplicationClientTest::TestConsistencyOnExceptions()` and `Lucene.Net.Replicator.IndexReplicationClientTest::TestConsistencyOnExceptions()` were failing due to to exceptions being raised on the worker thread and missing locks, which have both been addressed.
+* [#535](https://github.com/apache/lucenenet/pull/535) - Added `[SuppressCodecs]` attribute where required for custom Lucene.NET tests
+* [#536](https://github.com/apache/lucenenet/pull/536) - Modified all `TermsEnum.MoveNext()` methods to return a check for `null` rather than returning `true`
+* [#537](https://github.com/apache/lucenenet/pull/537) - `Lucene.Net.TestFramework.Index.BasePostingsFormatTestCase`: Removed `IndexOptions.NONE` from the list of available options, since it is not a valid test option
+* [#539](https://github.com/apache/lucenenet/pull/539) - `Lucene.Net.Grouping.Term.TermAllGroupHeadsCollector`: Use `NumericUtils.SingleToSortableInt32()` to compare floating point numbers (Fixes `AllGroupHeadCollectorTest.TestRandom()` on .NET Framework x86).
+* [#540](https://github.com/apache/lucenenet/pull/540) - `Lucene.Net.Tests.Util.TestPriorityQueue`: Fixed issues with comparers after introducing `J2N.Randomizer`, which produces negative random numbers.
+* [#541](https://github.com/apache/lucenenet/pull/541) - `Lucene.Net.Codecs.SimpleText.SimpleTextFieldsReader::NextDoc()`: Fixed assert that was throwing on `BytesRef.Utf8ToString()`

+* [#551](https://github.com/apache/lucenenet/pull/551) - `Lucene.Net.QueryParser.Flexible.Standard`: Fixed calendar handling on .NET Core
+* [#552](https://github.com/apache/lucenenet/pull/552) - `Lucene.Net.Suggest.Jaspell.JaspellTernarySearchTree`: Fixed random number generator so it produces random numbers
+* [#553](https://github.com/apache/lucenenet/pull/553), [#609](https://github.com/apache/lucenenet/pull/609) - `Lucene.Net.TestFramework.Util.TestUtil::RandomAnalysisString()`: Fixed `ArgumentOutOfRangeException` when passed a `maxLength` of 0.

+* [#545](https://github.com/apache/lucenenet/pull/545), [#565](https://github.com/apache/lucenenet/pull/565) - `Lucene.Net.Index.TestDuelingCodecs::TestEquals()`: There was a missing ! in `Lucene.Net.Codecs.BlockTreeTermsReader.IntersectEnum.Frame::Load()` that was inverting the logic, causing this test to fail intermittently.
+* [#549](https://github.com/apache/lucenenet/pull/549), [#566](https://github.com/apache/lucenenet/pull/566) - `Lucene.Net.Search.TestJoinUtil::TestMultiValueRandomJoin()`: Fixed x86 floating point precision issue on .NET Framework
+* [#568](https://github.com/apache/lucenenet/pull/568) - `Lucene.Net.Search.Spell.TestSpellChecker::TestConcurrentAccess()`: Fixed issues that were causing the test to hang due to concurrency problems.
+* [#513](https://github.com/apache/lucenenet/pull/513), [#572](https://github.com/apache/lucenenet/pull/572) - Updated `ControlledRealTimeReopenThread` to correctly handle timing (thanks @rclabo)
+* `Lucene.Net.Support.Collections.ReverseComparer<T>`: Replaced `CaseInsensitiveComparer` with `J2N.Collections.Generic.Comparer<T>`. This only affects tests.

+* [#606](https://github.com/apache/lucenenet/pull/606) - `Lucene.Net.Search.FieldCacheImpl.Cache<TKey, TValue>::Put()`: Logic was inverted on `innerCache` field so the value was being updated if exists, when it should not be updated in this case
+* [#606](https://github.com/apache/lucenenet/pull/606) - `Lucene.Net.Search.FieldCacheImpl::Cache<TKey, TValue> (Put + Get)`: Fixed issue with `InitReader()` being called prior to adding the item to the cache when it should be called after
+* [#619](https://github.com/apache/lucenenet/pull/619) - `Lucene.Net.Spatial.Query.SpatialArgs::ctor()`: Set `operation` and `shape` fields rather than calling the virtual properties to set them (which can cause initialization issues for subclasses)
+
+### Improvements
+* [#538](https://github.com/apache/lucenenet/pull/538) - `Lucene.Net.TestFramework.Search.CheckHits::CheckHitCollector()`: Removed unnecessary call to `Convert.ToInt32()` and simplified collection initialization.

+ * Low-level holder types (such as BytesRef, CharsRef, etc.)
+ * Stateless `IComparer<T>` implementations that are publicly exposed directly or through collections
+* [#568](https://github.com/apache/lucenenet/pull/568) - `Lucene.Net.TestFramework.Util.LuceneTestCase::NewSearcher()`: Added missing event handler to shut down `LimitedConcurrencyLevelTaskScheduler` to prevent it from accepting new work when we are attempting to end the background process.
+* [#568](https://github.com/apache/lucenenet/pull/568) - `Lucene.Net.Support`: Factored out `ICallable<V>` and `ICompletionService<V>` interfaces, as they are not needed
+* [#570](https://github.com/apache/lucenenet/pull/570) - **PERFORMANCE:** `Lucene.Net.Search.NumericRangeQuery`: Eliminated boxing when converting from T to the numeric type and when comparing equality
+* [#570](https://github.com/apache/lucenenet/pull/570) - **PERFORMANCE:** `Lucene.Net.Suggest.Jaspell`: Use J2N numeric types to eliminate boxing

+* [#570](https://github.com/apache/lucenenet/pull/570) - **PERFORMANCE:** `Lucene.Net.Classification.Utils.DatasetSplitter`: Removed duplicate calls to field methods and stored values in local variables. Use default round-trip format from J2N.
+* [#570](https://github.com/apache/lucenenet/pull/570) - **PERFORMANCE:** `Lucene.Net.Search.FieldCacheRangeFilter`: Use `HasValue` and `Value` for nullable value types rather casting and comparing to null
+* [#574](https://github.com/apache/lucenenet/pull/574), [#583](https://github.com/apache/lucenenet/pull/583) - **SWEEP:** - Removed unnecessary nullable value types

+* [#580](https://github.com/apache/lucenenet/pull/580) - `Lucene.Net.QueryParsers.Classic.QueryParserBase`: Use `TryParse()` instead of `Parse()` to parse numeric values. Use the current culture, but fall back to invariant culture.
+* [#582](https://github.com/apache/lucenenet/pull/582) - **PERFORAMANCE:** `Lucene.Net.Search.FieldCacheRangeFilter`: Eliminated boxing in `Equals()` check
+* [#584](https://github.com/apache/lucenenet/pull/584) - `Lucene.Net.Expressions.SimpleBindings`: Added collection initializer support. Updated `DistanceFacetsExample` and `ExpressionAggregationFacetsExample` to demonstrate usage.

+### New Features
+* [#288](https://github.com/apache/lucenenet/pull/288), [#547](https://github.com/apache/lucenenet/pull/547) - `Lucene.Net.TestFramework`: Fixed random seed functionality so it is repeatable, so random tests can be more easily debugged. The random seed and how to configure a test assembly to repeat the same result is appended to the output message of the test (which becomes visible upon failure). The `J2N.Randomizer` class was used to provide random numbers, which uses the same implement [...]
