# Changelog
All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [0.11.0](https://github.com/microsoft/regorus/compare/regorus-v0.10.1...regorus-v0.11.0) - 2026-07-21

### Added

- *(compiler)* support registered host-await builtins for natural function call syntax ([#667](https://github.com/microsoft/regorus/pull/667))
- *(value)* introduce Set storage abstraction ([#740](https://github.com/microsoft/regorus/pull/740))

### Fixed

- *(rvm)* assert every-quantifier results so failing cases don't pass ([#765](https://github.com/microsoft/regorus/pull/765))
- `Engine::add_data` now deep-merges nested data documents instead of only merging top-level keys. Adding `{ "a": { "x": 1 } }` followed by `{ "a": { "y": 2 } }` now yields `{ "a": { "x": 1, "y": 2 } }` (matching OPA's data-document merge). Nested sets under a shared key are unioned. Only genuine leaf conflicts (the same path holding two different values) are reported as errors. ([#760](https://github.com/microsoft/regorus/pull/760))
- A zero-arg function producing two different complete values (e.g. `f() := { "a": 1 }` and `f() := { "b": 2 }`) is now reported as a conflict, matching OPA's complete-rule semantics, instead of silently combining the outputs.

### Security

- `Engine::add_data` now rejects data nested beyond 128 levels instead of risking a stack overflow on adversarially deep input.

## [0.10.1](https://github.com/microsoft/regorus/compare/regorus-v0.10.0...regorus-v0.10.1) - 2026-05-22
