# CHANGELOG

## master

## 1.1.0 (2021-03-08)

### Summary

Errors are now organized by `RBS::BaseError`, `RBS::ParsingError`, `RBS::LoadingError`, and `RBS::DefinitionError`.
The library users can rescue RBS related errors with `RBS::BaseError`, parsing errors with `RBS::ParsingError`, and other errors with `RBS::LoadingError` and `RBS::DefinitionErrors`.

Updating a part of environments are supported. Library users can remove declarations read from a set of files, adding new declarations, running name resolution related to the new decls, and deleting `DefinitionBuilder` caches related to the changes.
See `RBS::Environment#reject`, `RBS::Environment#resolve_type_names`, `RBS::AncestorGraph`, and `RBS::DefinitionBuilder#update`.

`RBS::DefinitionBuilder#build_singleton` now returns definitions containing `instance` type, which had returned resolved class instance types. This is a breaking change, but we consider it a bug fix because `RBS::DefinitionBuilder#build_instance` has returned `instance` types and `#build_singleton` has returned `class` type.
