-# EFX Toolkit 1.3.0 Release Notes
+# EFX Toolkit 2.0.0-alpha.1 Release Notes
 
 _The EFX Toolkit for Java developers is a library that enables the transpilation of [EFX](https://docs.ted.europa.eu/eforms/latest/efx) expressions and templates to different target languages. It also includes an implementation of an EFX-to-XPath transpiler._
 
 ---
 ## In this release:
 
-- Updated the XPath 2.0 parser, XPathContextualizer and XPathScriptGenerator to correctly translate sequences. 
-- Improved numeric formatting. The EfxTranslator API now includes overloaded methods that permit control of numeric formatting. The existing API has been preserved.
-- Improved handling of multilingual text fields by adding automatic selection of the visualisation language.
+This release:
+- Improves translation of EFX-1.
+- Adds support for translating EFX-2 expressions and templates. 
+- Removes support of the obsolete EFX versions included in pre-release versions of the SDK (SDK 0.x.x).
+- Introduces some breaking changes in the interfaces that need to be implemented by new translators (SymbolResolver, ScriptGenerator, MarkupGenerator).
+
+## EFX-1 Support
+
+Although this is a pre-release version of the EFX Toolkit, it provides production-level support for EFX-1 transpilation. 
+EFX-1 is the current version of EFX released with SDK 1. Transpilation of EFX-1 to XPath is on par with the EFX Toolkit 1.3.0. 
+
+## EFX-2 Support
+
+The new version of EFX is still under development and will be released with SDK 2.0.0. For more information of EFX-2 see the release notes of the eForms SDK 2.0.0-alpha.1.
+
+## Breaking changes
+
+For users of the Toolkit that have implemented custom transpilers, this release contains a few breaking changes. 
+More specifically:
+- Some additional methods have been added to the SymbolResolver, ScriptGenerator and MarkupGenerator API. As a guide for your implementations please look a the implementations included in the EFX Toolkit for use by the EFX-to-XPath transpilation.
+- Some deprecated methods were removed.
+- An extensive refactoring in the type management system has rearranged the package structure. As a result some import statements i your code will need to be updated.
+
+Users of the Toolkit that only use the included EFX-to-XPath transpiler will not be affected by the above changes.
+
+## Future development
+
+Further alpha and beta releases of SDK 2 and EFX Toolkit 2 will be issued. While in "alpha" development stage, further braking changes may be introduced. SDK 2 and EFX 2 are expected to continue to be under development util late 2023.
