 ## [Unreleased]
 
 ### Added
 
+- Trivial recovery strategy to generate model elements for unresolved proxy objects
+- Parser: `TextBlock`s are converted to `TextBockReference`s so that model elements are generated for text blocks
+
 ### Changed
 
+- Minimum required Java version: Java 17
+- Supported Eclipse version: 2022-12
+- Third variant: bindings of parameters and local variables are also resolved

 ### Security
 
+## [5.1.0] - 2022-01-21
+
+From here, independent development by the Institute of Information Security and Dependability (KASTEL) at the Karlsruher Institute of Technology (KIT) resulting in the following changes.
+
+### Added
+
+- Meta-model support for features of Java 7-15:
+    - Java 7
+        - Diamond in class instance creation expressions
+        - `try`-with-resources statements
+        - Multi-`catch`
+        - Binary integer literals
+    - Java 8
+        - Lambda expressions
+        - Method reference expressions
+        - Receiver parameters
+        - Default interface methods
+        - Further positions of annotations
+    - Java 9
+        - Modules
+    - Java 10/11
+        - `var` as local variable type
+    - Java 14
+        - Switch expressions
+    - Java 15
+        - Text blocks
+- Meta-model extensions:
+    - `origin` field in the `JavaRoot` to represent the source (source file, class file, file from an archive, binding) of a Java model
+    - `Reference`s include an optional list of `TypeReference`s to store concrete types and type arguments in contexts in which the types are usually inferred
+- Manual printer implementation
+- Parser implementation based on Eclipse JDT which converts the AST to a model
+- First variant for the reference resolution: Eclipse JDT bindings are used to directly set references
+- Third variant for the reference resolution (as combination of first and second one): proxy objects which are set for references can be resolved after the parsing (based on the Eclipse JDT bindings) or on demand
+
+### Changed
+
+- Minimum required Java version: Java 11
+- Supported Eclipse version: 2021-12
+- Update to Apache Commons Byte Code Engineering Library 6.5.0
+- Meta-model: `TypeReference` inherits from `ArrayTypeable` so that a type can store information about array dimensions and if it is an array
+- Turned the extended reference resolution mechanism from the original version into the second variant for the reference resolution: proxy objects which are set for references are resolved on demand
+- Standalone version is based on the first variant
+
+### Removed
+
+- Java syntax definition in CS specification language and the generated parser and printer
+
+### Known Issues
+
+- First variant: ends in `StackOverflowException` because of an endless loop, also affects standalone version
+
+## Original JaMoPP Version - before 2019
+
+Originally, developed by DevBoost GmbH and Software Technology Group, Dresden University of Technology. It consists of the development up to version [1.4.0] and the [development after 1.4.0] resulting in the following features.
+
+- Ecore-based meta-model for the Java programming language covering the syntax up to and including Java 6
+- Definition of Java syntax in CS specification language of EMFText to generate a parser (Java source code -> Java model) and printer (Java model -> Java source code)
+- Loader for class files which generates Java models from class files (based on Apache Commons Byte Code Engineering Library 6.2.0)
+- Extended reference resolution mechanisms of generated EMFText code to connect Java models by language-specific links
+- Integration into the Eclipse IDE
+- Tests for the parsing (checks if generated model contains the expected elements)
+- Tests for the parsing and printing (checks if printed code is equal to parsed code by parsing both source codes with Eclipse JDT and comparing the resulting ASTs)
