 # Changelog
 
+## 3.0.0 2023-07-24
+
+### Features
+- Updates to the AWS Cryptographic Material Providers Library for Java,
+  a pivotal dependency of the this library,
+  introduce Thread Safe Cryptographic Materials Caches (CMCs):
+  - Storm Tracking Cache  
+    Safe for use in a multi threaded environment,  
+    tries to prevent redundant or overly parallel backend calls.  
+    See [Spec changes](https://github.com/awslabs/aws-encryption-sdk-specification/blob/ce9a4062124edc5085c66a4f10742e15aa039b34/changes/2023-06-19_thread_safe_cache/change.md) for details.  
+  - Multi Threaded Cache  
+    Safe for use in a multi threaded environment,  
+    but no extra functionality
+- Examples for using the Enhanced Client via Lombok Annotation and TableSchemaBuilder
+- Detection of ignored DynamoDB Encryption Configuration Tags due to Nested Data Models
+- Multi Threading Example
+
+### BREAKING CHANGES
+- Updates to the AWS Cryptographic Material Providers Library for Java,
+  a pivotal dependency of the this library,
+  introduce the following breaking changes:
+  - CMCs:  
+    - Original Cryptographic Materials Cache has been renamed to Single Threaded Cache  
+    - `CreateCryptographicMaterialsCacheInput` now ONLY accepts `CacheType`,  
+    which determines which, if any, of the three implemented CMCs will be returned.  
+    - The `DefaultCache` is `StormTrackingCache`  
+  - `CreateAwsKmsHierarchicalKeyringInput`:  
+    - no longer has a `maxCacheSize` field   
+    - now has an optional `cache` field for a `CacheType`  
+  - Hierarchical Keyring's Key Store:  
+    - The Hierarchical Keyring's Key Store's Data Structure has changed.  
+      As such, entries persisted in the Key Store with prior versions of this library are NOT compatible.  
+      Instead, we recommend Creating a new DynamoDB Table for this version of the Key Store.  
+    - The Key Store's `CreateKeyInput` now takes:  
+      - An Optional `String branchKeyIdentifier`  
+      - An Optional `EncryptionContext encryptionContext`  
+        - This `encryptionContext` will be added to the Encryption Context sent to KMS prefixed with `aws-crypto-ec:`  
+    - Creating a Key now also calls KMS:ReEncrypt  
+    - `CreateKeyStore` no longer creates a GSI  
+    - The Encryption Context used with KMS' `GenerateDataKeyWithoutPlaintext` no longer includes the discarded GSI's `status`.  
+    - More details about the Key Store's changes are available in our Specification:  
+      - [2023-07-12 Update Key Store](https://github.com/awslabs/aws-encryption-sdk-specification/tree/master/changes/2023_7_12_update-keystore-structure)
+      - [KeyStore Specification](https://github.com/awslabs/aws-encryption-sdk-specification/blob/master/framework/branch-key-store.md)
+
+### Fix
+- With the Enhanced Client, Identify Only Index attributes for Sign Only,
+  NOT all Key Attributes, such as Auto Generated Last Modified Time Stamp.
+
+### Maintenance
+- A variety of fixes to the libraries CI and testing
+
 ## 3.0.0-preview-2 2023-06-09
