 # Singulink Collections Version History
 
+## V3.0
+### Singulink.Collections
+- Breaking change: Deprecated `Singulink.Collections.Abstractions` package. Types have been merged into the main `Singulink.Collections` package.
+- Performance improvements to `ListDictionary<,>.ValueList` and `HashSetDictionary<,>.ValueSet`.
+- Minor documentation fixes.
+
 ## V2.0
 ### All packages
 - Removed support for end-of-life .NET and .NET Framework runtimes with a build warning if used on an unsupported runtime

 - `Map`: Collection of two types of values that map between each other in a bidirectional one-to-one relationship.
 - `ReadOnlyHashSet`: Fast read-only wrapper around a HashSet (instead of going through `ISet<>`).
 - `ReadOnlyList`: Fast read-only wrapper around a List (instead of going through `IList<>`).
-- A full set of interfaces for the new collections as well as an `IReadOnlySet<>` polyfill for .NET Standard.

 **Singulink.Collections.Weak** provides a set of collection classes that store weak references to values so that the garbage collector is free to reclaim the memory they use when they aren't being referenced anymore. The values returned by the collections will never be `null` - if the value was garbage collected then the collection behaves as if the value was removed from the collection.
