The Apache Fory team is pleased to announce the 1.0.0 release. This milestone release includes 84 PRs from 11 distinct contributors and turns the cross-language runtime into the default path across supported languages. See the Install page to get the libraries for your platform.

Highlights

Apache Fory 1.0.0 standardizes the cross-language serialization model. The unified xlang type system is now the default mode across languages, with compatible-mode reads, simplified field ordering, and better list/array compatibility. The release also adds decimal and bfloat16 support for xlang serialization.

The language runtimes continue to converge around the same schema and metadata model. Nested container and field codec support landed across Rust, C++, C#, Go, Dart, Python, and Swift. Kotlin gains xlang, KSP, and schema IDL support, while Scala adds schema IDL support and updated generated annotations.

This release also expands deployment coverage and performance work. Java gains Android serialization support, annotation processor support and nested type-use serialization metadata. Dart typed-container fast paths and generated struct optimizations improve throughput, alongside refreshed benchmark plots.
