 This changelog summarizes major changes between Truffle versions relevant to languages implementors building upon the Truffle framework. The main focus is on APIs exported by Truffle.
 
+## Version 26.0
+* GR-65048 Added support for Truffle using the fallback runtime (`-Dtruffle.UseFallbackRuntime=true`) on IBM system z by introducing `CPUArchitecture.S390X` and `OS.ZOS`.
+
 ## Version 25.0
 * GR-31495 Added ability to specify language and instrument specific options using `Source.Builder.option(String, String)`. Languages may describe available source options by implementing `TruffleLanguage.getSourceOptionDescriptors()` and `TruffleInstrument.getSourceOptionDescriptors()` respectively.
 * GR-61493 Added `RootNode.prepareForCall` which allows root nodes to prepare themselves for use as a call target (or to validate whether they can be used as a call target).
