This release contains some changes to some aspects of the API that are either legacy or de-facto internal (from before the Go toolchain had an explicit idea of that). Any external module using these will experience these as breaking changes, but we know of no such caller and so are admitting these without a major release in the interests of not creating churn for users of the main API.
encoding/gob support utilities removed: we added these as a concession to HashiCorp who wanted to try to send cty values over some legacy protocols/formats used by legacy versions of HashiCorp Terraform. In the end those efforts were not successful for other reasons and so no Terraform release ever relied on this functionality.
encoding/gob support has been burdensome due to how its unmarshaler interface is defined and so cty values and types are no longer automatically compatible with encoding/gob. Callers should instead use explicitly-implemented encodings, such as the built-in JSON and msgpack encodings or external libraries which use the public cty API to encode and decode.
cty now requires Go 1.18: although the main API is not yet making any use of type parameters, we've begun to adopt it in the hope of improving the maintainability of some internal details, starting with the backing implementation of set types.
Since type parameters are not supported by earlier versions of the Go compiler, callers must upgrade to Go 1.18 before using cty v1.11.0 or later.
Other changes in this release
cty: Improved performance when comparing nonzero numbers to zero, by performing a relatively-cheap sign check on both numbers before falling back on the more expensive general equality implementation. (#125)
cty: It's now possible to use capsule types in the elements of sets. Previously cty would panic if asked to construct a value of a set type whose element type either is or contains a capsule type, but there is now explicit support for storing encapsulated values in sets and optional (but recommended) support for a custom hashing function per type in order to improve performance for sets with a large number of elements.
convert: Unify will no longer panic when asked to find a common base type for a tuple type and a list of unknown element type, and will instead just signal that such a unification is not possible. (#126)
stdlib: FlattenFunc will no longer panic if it encounters a null value of a type that would normally be subject to flattening. Instead, it will treat it in the same way as a null value of any non-flattenable type. (#129)
