This release enables the new evalv3 evaluator by default, and introduces initial support for absolute packages.
Changes which may break some users are marked below with: ⚠️
Evaluator
⚠️ The new evaluator is now enabled by default, given that the majority of our test suite and projects in Unity are now working. While a few regressions remain, dozens of bugs are fixed by the new evaluator, and it already shows better performance by orders of magnitude on many projects.
The old evaluator is still accessible via CUE_EXPERIMENT=evalv3=0. If you encounter any errors or other problems, please file an issue with details.
For more information, see our new guide on upgrading from evalv2 to evalv3.
Closedness in evalv3 has been revisited to match the semantics of evalv2 much more closely, while at the same time reducing its overhead for larger configurations. This fixes most "field not allowed" regressions and improves the performance of some configurations by up to 2-5x.
cmd/cue
Initial support for absolute packages is introduced, which allow specifying a remote package at a particular version such as cue export foo.com/data@v1.2.3 or cue vet foo.com/schema@v1.2.3 -d '#schema' data.yaml.
cue get go no longer fails on Go strings containing certain character escape sequences or non-UTF8 bytes.
Encodings
Empty YAML files are now decoded as *null | _ rather than null, allowing them to be unified with struct schemas as if they were an empty struct.
