 ### New Features and Improvements
 
+- Updated Protocol Buffers from 3.24.0 to 4.33.0 for improved performance and latest features
+- Updated gRPC dependencies from 1.58.0 to 1.76.0 for enhanced stability and security
+- Updated SLF4J logging framework from 1.7.36 to 2.0.17 for modern logging capabilities
+
 ### Bug Fixes
 
 ### Documentation
 
+- Updated README.md with new dependency versions
+- Updated protoc compiler version recommendations
+- Updated Logback version compatibility for SLF4J 2.0
+
 ### Internal Changes
 
+- Updated maven-compiler-plugin from 3.11.0 to 3.14.1
+- All gRPC artifacts now consistently use version 1.76.0
+
 ### API Changes
+
+**Breaking Changes**
+
+- **Protocol Buffers 4.x Migration**: If you use the regular JAR (not the fat JAR), you must upgrade to protobuf-java 4.33.0 and regenerate any custom `.proto` files using protoc 4.x
+  - Download protoc 4.33.0 from: https://github.com/protocolbuffers/protobuf/releases/tag/v33.0
+  - Regenerate proto files: `protoc --java_out=src/main/java src/main/proto/record.proto`
+  - Protobuf 4.x is binary-compatible over the wire with 3.x, but generated Java code may differ
+
+- **SLF4J 2.0 Migration**: If you use a logging implementation, you may need to update it:
+  - `slf4j-simple`: Use version 2.0.17 or later
+  - `logback-classic`: Use version 1.4.14 or later (for SLF4J 2.0 compatibility)
+  - `log4j-slf4j-impl`: Use version 2.20.0 or later
+
+**Note**: If you use the fat JAR (`jar-with-dependencies`), all dependencies are bundled and no action is required.
