v3.1.5

What's new

• Fixed ConcurrentBidirectionalDictionary.Clear to release locks that were already acquired if lock acquisition fails.
• Fixed ConcurrentBidirectionalDictionary concurrencyLevel validation to reject values that would overflow internal lock array sizing.
• Fixed ReadOnlyBidirectionalDictionary non-generic enumerator bounds checks so Current, Entry, Key, and Value throw before enumeration starts or after it ends.
• Added nullable annotations for supported TryGetValue, Remove, and TryRemove out parameters.

v3.1.4

What's new:

• Fixed ICollection.CopyTo on Keys/Values of ReadOnlyBidirectionalDictionary, which assumed the underlying collection implemented non-generic ICollection

v3.1.3

What's new

• Value comparer usage is fixed for key-value pair contains and remove operations.
• Indexer assignment is fixed to preserve the stored key instance in the inverse dictionary.
• Concurrent dictionary value updates are fixed to keep inverse mappings consistent.

v2.0.2

What's new

• Value comparer usage is fixed for key-value pair contains and remove operations.
• Indexer assignment is fixed to preserve the stored key instance in the inverse dictionary.

v1.4.2

What's new

• Value comparer usage is fixed for key-value pair contains and remove operations.
• Indexer assignment is fixed to preserve the stored key instance in the inverse dictionary.

v3.1.2

What's new

• Added missing documentation
• Added debug symbols

v3.1.1

What's new

• Documentation fix

v3.1.0

What's new

• ConcurrentBidirectionalDictionary<TKey, TValue> — thread-safe variant of BidirectionalDictionary<TKey, TValue>.
  Thanks to @DarkRubin for proposition such variant!

v3.0.0

What's New

• Added non-generic IDictionary support.
• Improved enumeration performance.
• Added benchmarks.
• Expanded test coverage.

Breaking Changes

• Replaced public key and value collection types with custom collection types.
• Replaced mutable dictionary enumeration with a custom enumerator.
• Changed read-only dictionary enumeration to return generic key/value pair enumerators.
• Made the backing dictionary private, which may affect derived classes.

Fixes

• Fixed netstandard2.0-specific bug where the IEnumerable constructor overload with a custom key comparer does not preserve that comparer.
• Improved exception messages.
• Updated CI and docs.

v2.0.1

Fixed netstandard2.0-specific bug where the IEnumerable constructor overload with a custom key comparer does not preserve that comparer.
