[0.9.0] - 2020-05-25

This version requires Unity 2019.3.12f1+

Added

  • Added RemoveAt and RemoveRange to list containers in collections. These methods remove elements in a list container while preserving the order of the list. These methods are slower than Remove*SwapBack methods and as shuch, you should use Remove*SwapBack if you don't want to preserve the order inside \*List container.

Changed

  • Updated package com.unity.burst to version 1.3.0-preview.12.

    Removed

  • Removed expired APIs for UnsafeHashMap.Length
  • Removed expired APIs for NativeHashMap.Length

Fixed

  • Moved NativeMultiHashMap.Remove<TValueEQ>(TKey key, TValueEq value) into an extension method and made it Burst compatible
  • Fixed a bug in *HashMap.Remove to not throw when removing from empty hash map.

[0.8.0] - 2020-04-24

Added

  • Added Native/UnsafeBitArray.Copy for copying or shifting bits inside array.
  • Added UnsafeAtomicCounter32/64 providing helper interface for atomic counter functionality.
  • Added NativeBitArray providing arbitrary sized bit array functionality with safety mechanism.

Changed

  • Bumped Burst version to improve compile time and fix multiple bugs.

Deprecated

  • Deprecated IJobNativeMultiHashMapMergedSharedKeyIndices, JobNativeMultiHashMapUniqueHashExtensions, IJobNativeMultiHashMapVisitKeyValue, JobNativeMultiHashMapVisitKeyValue, IJobNativeMultiHashMapVisitKeyMutableValue, JobNativeMultiHashMapVisitKeyMutableValue, and introduced NativeHashMap.GetUnsafeBucketData and NativeMultiHashMap.GetUnsafeBucketData to obtain internals to implement deprecated functionality inside user code. If this functionality is used, the best is to copy deprecated code into user code.

Removed

  • Removed expired API class TerminatesProgramAttribute

[0.7.1] - 2020-04-08

Deprecated

  • Deprecated Length property from NativeHashMap, UnsafeHashMap, NativeMultiHashMap, UnsafeMultiHashMap, NativeQueue, and replaced it with Count() to reflect that there is computation being done.

Fixed

  • Fixed an issue where FixedListDebugView<T> only existed for IComparable types, which lead to a crash while debugging other types.
  • Removed code that made NativeStream incompatible with Burst.

[0.7.0] - 2020-03-13

Added

  • Added ability to dispose NativeKeyValueArrays from job (DisposeJob).

Changed

  • Upgraded Burst to fix multiple issues and introduced a native debugging feature.

Deprecated

  • Deprecated Length property from NativeHashMap, UnsafeHashMap, NativeMultiHashMap, UnsafeMultiHashMap, NativeQueue, and replaced it with Count() to reflect that there is computation being done.

Removed

  • Removed expired API CollectionHelper.CeilPow2()
  • Removed expired API CollectionHelper.lzcnt()
  • Removed expired API struct ResizableArray64Byte<T>

Fixed

  • Removed code that made NativeStream incompatible with Burst.

Added

  • Added ability to dispose UnsafeAppendBuffer from a DisposeJob.

Changed

[0.5.1] - 2020-01-28

Changed

  • Updated dependencies of this package.

[0.5.0] - 2020-01-16

Added

  • Added UnsafeRingQueue<T> providing fixed-size circular buffer functionality.
  • Added missing IDisposable constraint to UnsafeList and UnsafeBitArray.
  • Added ReadNextArray<T> to access a raw array (pointer and length) from an UnsafeAppendBuffer.Reader.
  • Added FixedString types, guaranteed binary-layout identical to NativeString types, which they are intended to replace.
  • Added FixedList<T> generic self-contained List struct
  • Added BitArray.SetBits with arbitrary ulong value.
  • Added BitArray.GetBits to retrieve bits as ulong value.

Changed

  • Changed UnsafeBitArray memory initialization option default to NativeArrayOptions.ClearMemory.
  • Changed FixedList structs to pad to natural alignment of item held in list

Deprecated

  • BlobAssetComputationContext.AssociateBlobAssetWithGameObject(int, GameObject) replaced by its UnityEngine.Object counterpart BlobAssetComputationContext.AssociateBlobAssetWithUnityObject(int, UnityEngine.Object) to allow association of BlobAsset with any kind of UnityEngine.Object derived types.
  • Adding removal dates to the API that have been deprecated but did not have the date set.

Removed

  • Removed IEquatable constraint from UnsafeList<T>.

Fixed

  • Fixed BitArray.SetBits.

[0.4.0] - 2019-12-16

This version requires Unity 2019.3.0f1+

New Features

  • Adding FixedListTN as a non-generic replacement for ResizableArrayN<T>.
  • Added UnsafeBitArray providing arbitrary sized bit array functionality.

Fixes

  • Updated performance package dependency to 1.3.2 which fixes an obsoletion warning
  • Adding [NativeDisableUnsafePtrRestriction] to UnsafeList to allow burst compilation.

[0.3.0] - 2019-12-03

New Features

  • Added fixed-size BitField32 and BitField64 bit array.

Changes

Removed the following deprecated API as announced in/before 0.1.1-preview:

  • Removed struct Concurrent and ToConcurrent() for NativeHashMap, NativeMultiHashMap and NativeQueue (replaced by the ParallelWriter API).
  • From NativeStream.cs: struct NativeStreamReader and struct NativeStreamWriter, replaced by struct NativeStream.Reader and struct NativeStream.Writer.
  • From NativeList.cs: ToDeferredJobArray() (replaced by AsDeferredJobArray() API).

[0.2.0] - 2019-11-22

This version requires Unity 2019.3 0b11+

New Features

  • Added fixed-size UTF-8 NativeString in sizes of 32, 64, 128, 512, and 4096 bytes.
  • Added HPC# functions for float-to-string and string-to-float.
  • Added HPC# functions for int-to-string and string-to-int.
  • Added HPC# functions for UTF16-to-UTF8 and UTF8-to-UTF16.
  • New Native(Multi)HashMap.GetKeyValueArrays that will query keys and values at the same time into parallel arrays.
  • Added UnsafeStream, UnsafeHashMap, and UnsafeMultiHashMap, providing functionality of NativeStream container but without any safety mechanism (intended for advanced users only).
  • Added AddNoResize methods to NativeList. When it's known ahead of time that list won't grow, these methods won't try to resize. Rather exception will be thrown if capacity is insufficient.
  • Added ParallelWriter support for UnsafeList.
  • Added UnsafeList.TrimExcess to set capacity to actual number of elements in the container.
  • Added convenience blittable UnsafeList<T> managed container with unmanaged T constraint.

Changes

  • UnsafeList.Resize now doesn't resize to lower capacity. User must call UnsafeList.SetCapacity to lower capacity of the list. This applies to all other containers based on UnsafeList.
  • Updated dependencies for this package.

Fixes

  • Fixed NativeQueue pool leak.

[0.1.1] - 2019-08-06

Fixes

  • NativeHashMap.Remove(TKey key, TValueEQ value) is now supported in bursted code.
  • Adding deprecated NativeList.ToDeferredJobArray() back in - Use AsDeferredJobArray() instead. The deprecated function will be removed in 3 months. This can not be auto-upgraded prior to Unity 2019.3.
  • Fixing bug where TryDequeue on an empty NativeQueue that previously had enqueued elements could leave it in an invalid state where Enqueue would fail silently afterwards.

Changes

  • Updated dependencies for this package.

[0.1.0] - 2019-07-30

New Features

  • NativeMultiHashMap.Remove(key, value) has been addded. It lets you remove all key & value pairs from the hashmap.
  • Added ability to dispose containers from job (DisposeJob).
  • Added UnsafeList.AddNoResize, and UnsafeList.AddRangeNoResize.
  • BlobString for storing string data in a blob

Upgrade guide

  • Native*.Concurrent is renamed to Native*.ParallelWriter.
  • Native*.ToConcurrent() function is renamed to Native*.AsParallelWriter().
  • NativeStreamReader/Writer structs are subclassed and renamed to NativeStream.Reader/Writer (note: changelot entry added retroactively).

Changes

  • Deprecated ToConcurrent, added AsParallelWriter instead.
  • Allocator is not an optional argument anymore, user must always specify the allocator.
  • Added Allocator to Unsafe*List container, and removed per method allocator argument.
  • Introduced memory intialization (NativeArrayOptions) argument to Unsafe*List constructor and Resize.

Fixes

  • Fixed UnsafeList.RemoveRangeSwapBack when removing elements near the end of UnsafeList.
  • Fixed safety handle use in NativeList.AddRange.

  • Imporoved documentation for NativeList
  • Added CollectionHelper.WriteLayout debug utility
